eXo Platform 3.5

## Chapter 3. eXo Core

The eXo Core is a set of common services, such as Authentication and Security, Organization, Database, Logging, JNDI, LDAP, Document reader, and other services, that are used by eXo products and modules. It also can be used in the business logic.

## 3.1. Database Creator

Database creator`DBCreator` is responsible for execution DDL script in runtime. A DDL script may contain templates for database name, user name and password which will be replaced by real values at execution time.

Three templates supported:

- `${database}` for database name;

- `${username}` for user name;

- `${password}` for user's password;

### 3.1.1. API

Service provide method for execute script for new database creation. Database name which are passed as parameter will be substituted in DDL script instead of `${database}` template. Returns `DBConnectionInfo` object (with all neccesary information of new database's connection) or throws `DBCreatorException` exception if any errors occurs in other case.

    public DBConnectionInfo createDatabase(String dbName) throws DBCreatorException;

For MSSQL and Sybase servers, use autocommit mode to set true for connection. It's due to after execution "create database" command newly created database not available for "use" command and therefore you can't create new user inside database per one script.

    public DBConnectionInfo getDBConnectionInfo(String dbName) throws DBCreatorException;

Return database connection information without database creation.

`db-connection` properties section contains parameters needed for connection to database server

There is four reserved and mandatory properties driverClassName, url, username and password. But db-connection may contain additonal properties.

For example, next additional proprites allows reconnect to MySQL database when connection was refused:

             <properties-param>

                <name>db-connection</name>

                ...

                <property name="validationQuery" value="select 1"/>

    GRANT "CONNECT" TO "${username}";
    GRANT "RESOURCE" TO "${username}";

## 3.2. Security Service

The purpose is to make a simple, unified way for the authentication and the storing/propagation of user sessions through all the eXo components and J2EE containers. JAAS is supposed to be the primary login mechanism but the Security Service framework should not prevent other (custom or standard) mechanisms from being used. You can learn more about JAAS in the Java Tutorial

### 3.2.1. Framework

The central point of this framework is the ConversationState object which stores all information about the state of the current user (very similar to the Session concept). The same ConversationState also stores acquired attributes of an Identity which is a set of principals to identify a user.

The ConversationState has definite lifetime. This object should be created when the user's identity becomes known by eXo (login procedure) and destroyed when the user leaves an eXo based application (logout procedure). Using JAAS it should happen in LoginModule's login() and logout() methods respectively.

#### ConversationState and ConversationRegistry

The ConversationState can be stored

- In a static local thread variable, or

- As a key-value pair in the ConversationRegistry component.

One or the other, or both methods can be used to set/retrieve the state at runtime. The most important thing is that they should be complementary, i.e. make sure that the conversation state is set before you try to use it.

Local Thread Variable: Storing the ConversationState in a static local thread variable makes it possible to represent it as a context (current user's state).

    ConversationState.setCurrent(conversationState);

    ....

    ConversationState.getCurrent();

Key-Value way

If you store the ConversationState inside the ConversationRegistry component as a set of key-value pairs, the session key is an arbitrary String (user name, ticket id, httpSessionId etc).

    conversationRegistry.register("key", conversationState);

    ...

    conversationRegistry.getState("key");

ConversationRegistry The ConversationRegistry is a mandatory component deployed into eXo Container as following:

    <component>

        <type>org.exoplatform.services.security.ConversationRegistry</type>

    </component>

#### Authenticator

An Authenticator is responsible for Identity creation, it consists of two methods:

- validateUser() accepts an array of credentials and returns the userId (which can be something different from the username).

- createIdentity() accepts the userId and returns a newly created Identity object.

    public interface Authenticator {

      /**

       * Authenticate user and return userId which can be different to username.

       * @param credentials - list of users credentials (such as name/password, X509 certificate etc)

       * @return userId

       * @throws LoginException

       * @throws Exception

       */

      String validateUser(Credential[] credentials) throws LoginException, Exception;

      /**

       * @param credentials - userId.

       * @return Identity

       * @throws Exception

       */

      Identity createIdentity(String userId) throws Exception;

    }

It is up to the application developer (and deployer) whether to use the Authenticator component(s) and how many implementations of this components should be deployed in eXo container. The developer is free to create an Identity object using a different way, but the Authenticator component is the highly recommended way from architectural considerations.

Typical functionality of the validateUser(Credential\[] credentials) method is the comparison of incoming credentials (username/password, digest etc) with those credentials that are stored in an implementation specific database. Then, validateUser(Credential\[] credentials) returns back the userId or throws a LoginException in a case of wrong credentials.

Default Authenticator implementation is org.exoplatform.services.organization.auth.OrganizationAuthenticatorImpl which compares incoming username/password credentials with the ones stored in OrganizationService. Configuration example:

    <component>

      <key>org.exoplatform.services.security.Authenticator</key>

      <type>org.exoplatform.services.organization.auth.OrganizationAuthenticatorImpl</type>

    </component>

### 3.2.2. Usage

#### JAAS login module

The framework described is not coupled with any authentication mechanism but the most logical and implemented by default is the JAAS Login module. The typical sequence looks as follows (see org.exoplatform.services.security.jaas.DefaultLoginModule):

- LoginModule.login() creates a list of credentials using standard JAAS Callbacks features, obtains an Authenticator instance, and creates an Identity object calling Authenticator.authenticate(..) method

    Authenticator authenticator = (Authenticator) container()

              .getComponentInstanceOfType(Authenticator.class);

    // RolesExtractor can be null

    RolesExtractor rolesExtractor = (RolesExtractor) container().

    getComponentInstanceOfType(RolesExtractor.class);

    Credential[] credentials = new Credential[] {new UsernameCredential(username), new PasswordCredential(password) };

    String userId = authenticator.validateUser(credentials);

    identity = authenticator.createIdentity(userId);

- LoginModule.commit() obtains the IdentityRegistry object, and register the identity using userId as a key.

When initializing the login module, you can set the option parameter "singleLogin". With this option you can disallow the same Identity to login for a second time.

By default singleLogin is disabled, so the same identity can be registered more than one time. Parameter can be passed in this form singleLogin=yes or singleLogin=true.

    IdentityRegistry identityRegistry = (IdentityRegistry) getContainer().getComponentInstanceOfType(IdentityRegistry.class);

    if (singleLogin && identityRegistry.getIdentity(identity.getUserId()) != null)

      throw new LoginException("User " + identity.getUserId() + " already logined.");

    identity.setSubject(subject);

    identityRegistry.register(identity);

In the case of using several LoginModules, JAAS allows to place the login() and commit() methods in different REQUIRED modules.

After that, the web application must use SetCurrentIdentityFilter. This filter obtains the ConversationRegistry object and tries to get the ConversationState by sessionId (HttpSession). If there is no ConversationState, then SetCurrentIdentityFilter will create a new one, register it and set it as current one using ConversationState.setCurrent(state).

- LoginModule.logout() can be called by JAASConversationStateListener, it extends ConversationStateListener.

This listener must be configured in web.xml. The method sessionDestroyed(HttpSessionEvent) is called by the ServletContainer. This method removes the ConversationState from the ConversationRegistry ConversationRegistry.unregister(sesionId) and calls the method LoginModule.logout().

    ConversationRegistry conversationRegistry = (ConversationRegistry) getContainer().getComponentInstanceOfType(ConversationRegistry.class);

    ConversationState conversationState = conversationRegistry.unregister(sesionId);

    if (conversationState != null) {

      log.info("Remove conversation state " + sesionId);

      if (conversationState.getAttribute(ConversationState.SUBJECT) != null) {

        Subject subject = (Subject) conversationState.getAttribute(ConversationState.SUBJECT);

        LoginContext ctx = new LoginContext("exo-domain",  subject);

        ctx.logout();

    } else {

      log.warn("Subject was not found in ConversationState attributes.");

    }

#### Predefinded JAAS login modules

There are several JAAS Login modules included in eXo Platform sources:

org.exoplatform.services.security.jaas.DefaultLoginModule which provides both authentication (using eXo Authenticator based mechanism) and authorization, filling Conversation Registry as it described in previous section. There are also several per-Application Server extensions of this login module which can be found in org.exoplatform.services.security.jaas package, which can be used in appropriate AS. In particular, we have dedicated Login modules for Tomcat, JBoss, Jonas and WebSphere.

Besides that, for the case when third party authentication mechanism required, we have org.exoplatform.services.security.jaas.IdentitySetLoginModule, which catches a login identity from third party "authenticating" login module and preforms eXo specific authorization job. In this case third party login module has to put login (user) name to the shared state map under "javax.security.auth.login.name" key and third party LM has to be configured before IdentitySetLoginModule like:

    exo {
       com.third.party.LoginModuleImpl required;
       org.exoplatform.services.security.jaas.IdentitySetLoginModule required;
    };

#### J2EE container authentication

As you know, when a user in JAAS is authenticated, a Subject is created as a result. This Subject represents the authenticated user. It is important to know and follow the rules regarding Subject filling which are specific for each J2EE server, where eXo Platform is deployed.

To make it workable for the particular J2EE server, it is necessary to add specific Principals/Credentials to the Subject to be propagated into the specific J2EE container implementation. We extended the DefaultLoginModule by overloading its commit() method with a dedicated logic, presently available for Tomcat, JBOSS and JONAS application servers.

Furthermore, you can use the optional RolesExtractor which is responsible for mapping primary Subject's principals (userId and a set of groups) to J2EE Roles:

    public interface RolesExtractor {

      Set <String> extractRoles(String userId, Set<MembershipEntry> memberships);

    }

This component may be used by Authenticator to create the Identity with a particular set of Roles.

## 3.3. Organization Service

OrganizationService is the service that allows to access the Organization model. This model is composed of:

- Users

- Groups

- Memberships

It is the basis of eXo personalization and authorizations in eXo and is used to all over the platform. The model is abstract and does not rely on any specific storage. Multiple implementations exist in eXo:

- Hibernate: for storage into a RDBMS

- Jndi: for storage into a directory such as an LDAP or MS Active Directory

- Jcr: for storage inside a Java Content Repository

### 3.3.1. Organizational Model

#### User

- Username used as the identified

- Profile (identity and preferences)

#### Group

Gather a set of users

- Applicative or business

- Tree structure

- No inheritance

- Expressed as /group/subgroup/subsubgroup

#### Membership

- Qualifies the group belonging

- "Member of group as XXX"

- Expressed as : manager:/organization/hr, *:/partners

### 3.3.2. Custom Organization Service implementation instructions

To create a custom organization service you need to implement a several interfaces and extend some classes which will be listed below.

#### Basic entities implementation

First of all you need to create classes implementing the following interfaces (each of which represent a basic unit of organization service):

- org.exoplatform.services.organization.User

  This is the interface for a User data model. The OrganizationService implementor can use the different strategy to implement this class, he can use the native field for each get method or use a Map to hold the user data.

- org.exoplatform.services.organization.UserProfile

  This is the interface for a UserProfile data model. The implementor should have an user map info in the implementation. The map should only accept the java.lang.String for the key and the value.

- org.exoplatform.services.organization.Group

  This is the interface for the group data model.

- org.exoplatform.services.organization.Membership

  This is the interface for the membership data model.

- org.exoplatform.services.organization.MembershipType

  This is the interface for the membership type data model.

### Note

After each set method is called the developer must call UserHandler.saveUser (GroupHandler.saveGroup, MembershipHandler.saveMembership etc.) method to persist the changes.

You can find examples of the mentioned above implementations at subversion server:

- UserImpl

- UserProfileImpl

- GroupImpl

- MembershipImpl

- MembershipTypeImpl

#### Unit handlers implementation

After you created basic organization service unit instances you need to create classess to handle them e.g. to persist changes, to add listener etc. For that purpose you need to implement a several interfaces correspondingly:

- User handler

  - org.exoplatform.services.organization.UserHandler

    This class is acted as a sub component of the organization service. It is used to manage the user account and broadcast the user event to all the registered listener in the organization service. The user event can be: new user event, update user event and delete user event. Each event should have 2 phases: pre event and post event. The method createUser , saveUser and removeUser broadcast the event at each phase so the listeners can handle the event properly.

  - org.exoplatform.services.organization.ExtendedUserHandler

    Optional. Implement it if you want to be able to use Digest access authentication i.e. you need a one way password encyption for authentication.

  - org.exoplatform.services.organization.UserEventListenerHandler

    Optional. Provides the ability to get the list of org.exoplatform.services.organization.UserEventListener. List should be unmodifiable to prevent modification outside of org.exoplatform.services.organization.UserHandler.

- User profile handler

  - org.exoplatform.services.organization.UserProfileHandler

    This interface is acted as a sub interface of the organization service. It is used to manage the the UserProfile record, the extra information of an user such address, phone... The interface should allow the developer create, delete and update a UserProfile. and broadcast the event to the user profile event listeners.

  - org.exoplatform.services.organization.UserProfileEventListenerHandler

    Optional. Provides the ability to get the list of org.exoplatform.services.organization.UserProfileEventListener. List should be unmodifiable to prevent modification outside of org.exoplatform.services.organization.UserProfileHandler.

- Group handler

  - org.exoplatform.services.organization.GroupHandler

    This class is acted as a sub component of the organization service. It is used to manage the group and broadcast the group event to all the registered listener in the organization service. The group event can be: new group event, update group event and delete group event. Each event should have 2 phases: pre event and post event. The methods createGroup, saveGroup and removeGroup broadcast the event at each phase so the listeners can handle the event properly.

  - org.exoplatform.services.organization.GroupEventListenerHandler

    Optional. Provides the ability to get the of org.exoplatform.services.organization.GroupEventListener. List should be unmodifiable to prevent modification outside of org.exoplatform.services.organization.GroupHandler.

- Membership handler

  - org.exoplatform.services.organization.MembershipHandler

    This class is acted as a sub component of the organization service. It is used to manage the membership - the relation of user , group, and membership type - and broadcast the membership event to all the registered listener in the organization service. The membership event can be: new linked membership and delete the membership type event. Each event should have 2 phases: pre event and post event. The method linkMembership and removeMembership broadcast the event at each phase so the listeners can handle the event properly.

  - org.exoplatform.services.organization.MembershipEventListenerHandler

    Optional. Provides the ability to get the of org.exoplatform.services.organization.MembershipEventListener. List should be unmodifiable to prevent modification outside of org.exoplatform.services.organization.MembershipHandler.

- Membership type handler

  - org.exoplatform.services.organization.MembershipTypeHandler

    This class is acted as a sub component of the organization service. It is used to manage the membership - the relation of user , group, and membership type - and broadcast the membership event to all the registered listener in the organization service. The membership event can be: new linked membership and delete the membership type event. Each event should have 2 phases: pre event and post event. The method linkMembership and removeMembership broadcast the event at each phase so the listeners can handle the event properly.

  - org.exoplatform.services.organization.MembershipTypeEventListenerHandler

    Optional. Provides the ability to get the list of org.exoplatform.services.organization.MembershipTypeEventListener. List should be unmodifiable to prevent modification outside of org.exoplatform.services.organization.MembershipTypeHandler.

You can find examples of the mentioned above implementations at subversion server:

- UserHandlerImpl

- UserProfileHandlerImpl

- GroupHandlerImpl

- MembershipHandlerImpl

- MembershipTypeHandlerImpl

#### Extending BaseOrganizationService class

Finally you need to create your main custom organization service class. It must extend org.exoplatform.services.organization.BaseOrganizationService. BaseOrganizationService class contains organization service unit handlers as protected fields, so you can initialize them in accordance to your purposes. It also has org.exoplatform.services.organization.OrganizationService interface methods' implementations. This is the class you need to mention in the configuration file if you want to use your custom organization service.

You can find example of such class at subversion server: JCROrganizationServiceImpl.

#### Verification of compliance

Make sure that your custom organization service implementation is fully compliant with Organization Service TCK tests. Tests are available as maven artifact:

groupId - org.exoplatform.core

artifactId - exo.core.component.organization.tests

You can find TCK tests package source code here

### Note

In order to be able to run unit tests you may need to configure the following maven plugins:

- maven-dependency-plugin

- build-helper-maven-plugin

- maven-surefire-plugin

Check pom.xml file to find out one of the ways to configure maven project object model. More detailed description you can find in the dedicated section called "Organization Service TCK tests configuration"

                          <string>Root</string>

                        </field>

                        <field name="email">

                          <string>root@localhost</string>

                        </field>

                        <field name="groups">

Params for membership type:

- type: The membership type's name.

- description: The membership type's description.

Params for group:

- name: The group's name

- parentId: The id of the parent group. If the parent id is null, it means that the group is at the first level. The parentId should have the form: /ancestor/parent

- description: The group's description

- label: The group's label

Params for user:

- userName: The user's name

- password: The user's password

- firstName: The user's first name

- lastName: The user's last name

- email: The user's email

- groups: The user's membership types and groups in which he consist.

## 3.5. Organization Listener

The Organization Service provides a mechanism to receive notifications when:

- A User is created, deleted or modified.

- A Group is created, deleted or modified.

- A Membership is created or removed.

This mechanism is very useful to cascade some actions when the organization model is modified. For example, it is currently used to :

- Initialize the personal portal pages.

- Initialize the personal calendars, address books and mail accounts in CS.

- Create drives and personal areas in ECM.

### 3.5.1. Writing your own listeners

To implement your own listener, you just need to write extend some existing listener classes. These classes define hooks that are invoked before or after operations are performed on organization model.

#### UserEventListener

To listen to user changes, you need to extend <>org.exoplatform.services.organization.UserEventListener</> :

    public class MyUserListener extends UserEventListener {

      public void preSave(User user, boolean isNew) throws Exception {

        System.out.println("Before " + (isNew?"creating":"updating") + " user " + user.getUserName());

      }

      public void postSave(User user, boolean isNew) throws Exception {

        System.out.println("After user " + user.getUserName() + (isNew?" created":" updated"));

      }

      public void preDelete(User user) throws Exception {

        System.out.println("Before deleting user " + user.getUserName());

      }

      public void preDelete(User user) throws Exception {

        System.out.println("After deleting user " + user.getUserName());

      }

    }

#### GroupEventListener

To listen group changes, you need to extend org.exoplatform.services.organization.GroupEventListener :

    public class MyGroupListener extends GroupEventListener {

      public void preSave(Group group, boolean isNew) throws Exception {

        System.out.println("Before " + (isNew?"creating":"updating") + " group " + group.getName());

      }

      public void postSave(Group group, boolean isNew) throws Exception {

        System.out.println("After group " + group.getName() + (isNew?" created":" updated"));

      }

      public void preDelete(Group group) throws Exception {

        System.out.println("Before deleting group " + group.getName());

      }

      public void preDelete(Group group) throws Exception {

        System.out.println("After deleting group " + group.getName());

      }

    }

#### MembershipEventListener

To listen to membership changes, you need to extend org.exoplatform.services.organization.MembershipEventListener :

    public class MyMembershipListener extends MembershipEventListener {

      public void preSave(Membership membership, boolean isNew) throws Exception {

        System.out.println("Before " + (isNew?"creating":"updating") + " membership.");

      }

      public void postSave(Membership membership, boolean isNew) throws Exception {

        System.out.println("After membership " + (isNew?" created":" updated"));

      }

      public void preDelete(Membership membership) throws Exception {

        System.out.println("Before deleting membership");

      }

      public void preDelete(Membership membership) throws Exception {

        System.out.println("After deleting membership");

      }

    }

### 3.5.2. Registering your listeners

Registering the listeners is then achieved by using the ExoContainer plugin mechanism. Learn more about it on the Service Configuration for Beginners article.

To effectively register organization service's listeners you simply need to use the addListenerPlugin seer injector.

So, the easiest way to register your listeners is to pack them into a .jar and create a configuration file into it under mylisteners.jar!/conf/portal/configuration.xml

    <?xml version="1.0" encoding="ISO-8859-1"?>

    <configuration>

     <external-component-plugins>

      <target-component>org.exoplatform.services.organization.OrganizationService</target-component>

       <component-plugin>

        <name>myuserplugin</name>

        <set-method>addListenerPlugin</set-method>

        <type>org.example.MyUserListener</type>

        <description></description>

       </component-plugin>

       <component-plugin>

        <name>mygroupplugin</name>

        <set-method>addListenerPlugin</set-method>

        <type>org.example.MyGroupListener</type>

        <description></description>

       </component-plugin>

       <component-plugin>

        <name>mymembershipplugin</name>

        <set-method>addListenerPlugin</set-method>

        <type>org.example.MyMembershipListener</type>

        <description></description>

       </component-plugin>

      </external-component-plugins>

    <configuration>

Now, simply deploy the jar under $TOMCAT_HOME/lib and your listeners are ready!

### Note

Be aware that you need to set proper RuntimePermission to be able to add or remove Listeners. To do that you need to grant the following permission for your code

    permission java.lang.RuntimePermission "manageListeners"

## 3.6. Update ConversationState when user's Membership changed

When a user logged in portal in ConversationRegistry added ConversationSate for this user. ConversationState keeps user's Identity that is actual for logged in time. In this case even user's Membership updated in OrganizationService ConversationState still keeps old (not actual Identity). User must logged out and loggin in again to update Identity. To fix this issue, need add special listener in configuration of OrganizationServicer. This listener is extended MembershipEventListener.

Example of configuration.

    <?xml version="1.0" encoding="ISO-8859-1"?>

    <configuration

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

       xsi:schemaLocation="http://www.exoplatform.org/xml/ns/kernel_1_2.xsd http://www.exoplatform.org/xml/ns/kernel_1_2.xsd"

       xmlns="http://www.exoplatform.org/xml/ns/kernel_1_2.xsd">

      <external-component-plugins>

        <target-component>org.exoplatform.services.organization.OrganizationService</target-component>

    .....

    .....

        <component-plugin>

          <name>MembershipUpdateListener</name>

          <set-method>addListenerPlugin</set-method>

          <type>org.exoplatform.services.organization.impl.MembershipUpdateListener</type>

        </component-plugin>

       <external-component-plugins>

    </configuration>

## 3.7. DB Schema creator service (JDBC implementation)

DB Schema Creator is responsible for creating database schema, using a DDL script inside service configuration or in an external file, calling:

      org.exoplatform.services.database.jdbc.DBSchemaCreator.createTables(String dsName, String script)

via

    org.exoplatform.services.database.jdbc.CreateDBSchemaPlugin component plugin

A configuration example:

    <component>

       <key>org.exoplatform.services.database.jdbc.DBSchemaCreator</key>

       <type>org.exoplatform.services.database.jdbc.DBSchemaCreator</type>

       <component-plugins>

          <component-plugin>

             <name>jcr.dbschema</name>

             <set-method>addPlugin</set-method>

             <type>org.exoplatform.services.database.jdbc.CreateDBSchemaPlugin</type>

             <init-params>

                <value-param>

                   <name>data-source</name>

                   <value>jdbcjcr</value>

                </value-param>

                <value-param>

                   <name>script-file</name>

                   <value>conf/storage/jcr-mjdbc.sql</value>

                </value-param>

             </init-params>

          </component-plugin>

      ........

An example of a DDL script:

    CREATE TABLE JCR_MITEM(
            ID VARCHAR(255) NOT NULL PRIMARY KEY,
            VERSION INTEGER NOT NULL,
            PATH VARCHAR(1024) NOT NULL
            );
    CREATE INDEX JCR_IDX_MITEM_PATH ON JCR_MITEM(PATH);

## 3.8. Database Configuration for Hibernate

As usual, it is quite simple to use our configuration XML syntax to configure and parametrize different Databases for eXo tables but also for your own use.

### 3.8.1. Generic configuration

The default DB configuration uses HSQLDB, a Java Database quite useful for demonstrations.

    <component>

       <key>org.exoplatform.services.database.HibernateService</key>

       <jmx-name>exo-service:type=HibernateService</jmx-name>

       <type>org.exoplatform.services.database.impl.HibernateServiceImpl</type>

       <init-params>

          <properties-param>

             <name>hibernate.properties</name>

             <description>Default Hibernate Service</description>

             <property name="hibernate.show_sql" value="false"/>

             <property name="hibernate.cglib.use_reflection_optimizer" value="true"/>

             <property name="hibernate.connection.url" value="jdbc:hsqldb:file:../temp/data/portal"/>

             <property name="hibernate.connection.driver_class" value="org.hsqldb.jdbcDriver"/>

             <property name="hibernate.connection.autocommit" value="true"/>

             <property name="hibernate.connection.username" value="sa"/>

             <property name="hibernate.connection.password" value=""/>

             <property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/>

             <property name="hibernate.c3p0.min_size" value="5"/>

             <property name="hibernate.c3p0.max_size" value="20"/>

             <property name="hibernate.c3p0.timeout" value="1800"/>

             <property name="hibernate.c3p0.max_statements" value="50"/>

          </properties-param>

       </init-params>

    </component>

In the init parameter section, we define the default hibernate properties including the DB URL, the driver and the credentials in use.

For any portals that configuration can be overridden, depending on the needs of your environment.

Several databases have been tested and can be used in production....which is not the case of HSQLDB, HSQLDB can only be used for development environments and for demonstrations.

### 3.8.2. Example DB configuration

For MySQL

    <component>

       <key>org.exoplatform.services.database.HibernateService</key>

       <jmx-name>database:type=HibernateService</jmx-name>

       <type>org.exoplatform.services.database.impl.HibernateServiceImpl</type>

       <init-params>

          <properties-param>

             <name>hibernate.properties</name>

             <description>Default Hibernate Service</description>

             <property name="hibernate.show_sql" value="false"/>

             <property name="hibernate.cglib.use_reflection_optimizer" value="true"/>

             <property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/exodb?relaxAutoCommit=true&amp;amp;autoReconnect=true&amp;amp;useUnicode=true&amp;amp;characterEncoding=utf8"/>

             <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/>

             <property name="hibernate.connection.autocommit" value="true"/>

             <property name="hibernate.connection.username" value="exo"/>

             <property name="hibernate.connection.password" value="exo"/>

             <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>

             <property name="hibernate.c3p0.min_size" value="5"/>

             <property name="hibernate.c3p0.max_size" value="20"/>

             <property name="hibernate.c3p0.timeout" value="1800"/>

             <property name="hibernate.c3p0.max_statements" value="50"/>

           </properties-param>

       </init-params>

    </component>

### 3.8.3. Registering custom Hibernate XML files into the service

It is possible to use the eXo hibernate service and register your hibernate hbm.xml files to leverage some add-on features of the service such as the table automatic creation as well as the cache of the hibernate session in a ThreadLocal object during all the request lifecycle. To do so, you just have to add a plugin and indicate the location of your files.

    <?xml version="1.0" encoding="ISO-8859-1"?>

    <configuration>

      <external-component-plugins>

        <target-component>org.exoplatform.services.database.HibernateService</target-component>

        <component-plugin>

          <name>add.hibernate.mapping</name>

          <set-method>addPlugin</set-method>

          <type>org.exoplatform.services.database.impl.AddHibernateMappingPlugin</type>

          <init-params>

            <values-param>

              <name>hibernate.mapping</name>

              <value>org/exoplatform/services/organization/impl/UserImpl.hbm.xml</value>

              <value>org/exoplatform/services/organization/impl/MembershipImpl.hbm.xml</value>

              <value>org/exoplatform/services/organization/impl/GroupImpl.hbm.xml</value>

              <value>org/exoplatform/services/organization/impl/MembershipTypeImpl.hbm.xml</value>

              <value>org/exoplatform/services/organization/impl/UserProfileData.hbm.xml</value>

            </values-param>

          </init-params>

        </component-plugin>

      </external-component-plugins>

    </configuration>

## 3.9. LDAP Configuration

You may decide to make eXo users to be mapped to an existing directory. eXo provides a flexible implementation of its OrganizationService on top of LDAP. It can be used on any LDAP compliant directory and even Active Directory. This page will guide you how to configure eXo Platform to work with your directory.

### 3.9.1. Quickstart

If you just want to have a look at how eXo works with ldap. eXo comes with a predefined ldap configuration. You just need to activate it and eXo will create all it needs to work at startup.

You need to have a working LDAP server and a user with write permissions.

- Open exo-tomcat/webapps/portal/WEB-INF/conf/configuration.xml and replace:

    <import>war:/conf/organization/hibernate-configuration.xml</import>

With

    <import>war:/conf/organization/ldap-configuration.xml</import>

- 0pen ldap-configuration.xml and update the providerURL, rootdn and password settings according to your environment

    <field name="providerURL"><string>ldap://127.0.0.1:389</string></field>

    <field name="rootdn"><string>CN=Manager,DC=MyCompany,DC=com</string></field>

    <field name="password"><string>secret</string></field>

- Delete exo-tomcat/temp/* to have a clean database and then start tomcat.

eXo starts and autocreates its organization model in your directory tree. Finally, the structure of the default LDAP schema looks like:

That's it! Now eXo uses your LDAP directory as its org model storage. Users, groups and memberships are now stored and retrieved from there. We suggest that you complete some guideline functions with eXo user management portlet and see what it changes in your directory tree.

### 3.9.2. Configuration

If you have an existing LDAP server, the eXo predefined settings will likely not match your directory structure. eXo LDAP organization service implementation was written with flexibility in mind and can certainly be configured to meet your requirements.

The configuration is done in ldap-configuration.xml file, and this section will explain the numerous parameters it contains.

#### Connection Settings

Firstly, start by connection settings which will tell eXo how to connect to your directory server. These settings are very close to JNDI API context parameters. This configuration is activated by the init-param ldap.config of service LDAPServiceImpl.

    <component>

      <key>org.exoplatform.services.ldap.LDAPService</key>

      <type>org.exoplatform.services.ldap.impl.LDAPServiceImpl</type>

      <init-params>

        <object-param>

          <name>ldap.config</name>

          <description>Default ldap config</description>

          <object type="org.exoplatform.services.ldap.impl.LDAPConnectionConfig">

            <field name="providerURL"><string>ldap://127.0.0.1:389,10.0.0.1:389</string></field>

            <field name="rootdn"><string>CN=Manager,DC=exoplatform,DC=org</string></field>

            <field name="password"><string>secret</string></field>

            <!-- field  name="authenticationType"><string>simple</string></field-->

            <field name="version"><string>3</string></field>

            <field  name="referralMode"><string>follow</string></field>

            <!-- field  name="serverName"><string>active.directory</string></field-->

            <field name="minConnection"><int>5</int></field>

            <field name="maxConnection"><int>10</int></field>

            <field name="timeout"><int>50000</int></field>

          </object>

        </object-param>

      </init-params>

    </component>

- providerURL: LDAP server URL (see PROVIDER_URL). For multiple ldap servers, use comma separated list of host:port (Ex. ldap://127.0.0.1:389,10.0.0.1:389).

- rootdn: dn of user that will be used by the service to authenticate on the server (see SECURITY_PRINCIPAL).

- password: password for user rootdn (see SECURITY_CREDENTIALS).

- authenticationType: type of authentication to be used (see SECURITY_AUTHENTICATION). Use one of none, simple, strong. Default is simple.

- version: LDAP protocol version (see java.naming.ldap.version). Set to 3 if your server supports LDAP V3.

- referalMode: one of follow, ignore,throw (see REFERRAL).

- serverName: you will need to set this to active.directory in order to work with Active Directory servers. Any other value will be ignore and the service will act as on a standard LDAP.

- maxConnection: the maximum number of connections per connection identity that can be maintained concurrently.

- minConnection: the number of connections per connection identity to create when initially creating a connection for the identity.

- timeout: the number of milliseconds that an idle connection may remain in the pool without being closed and removed from the pool.

#### Organization Service Configuration

Next, you need to configure the eXo OrganizationService to tell him how the directory is structured and how to interact with it. This is managed by a couple of of init-params : ldap.userDN.key and ldap.attribute.mapping in file ldap-configuration.xml (by default located at portal.war/WEB-INF/conf/organization)

    <component>

      <key>org.exoplatform.services.organization.OrganizationService</key>

      <type>org.exoplatform.services.organization.ldap.OrganizationServiceImpl</type>

      [...]

      <init-params>

        <value-param>

          <name>ldap.userDN.key</name>

          <description>The key used to compose user DN</description>

          <value>cn</value>

        </value-param>

        <object-param>

          <name>ldap.attribute.mapping</name>

          <description>ldap attribute mapping</description>

          <object type="org.exoplatform.services.organization.ldap.LDAPAttributeMapping">

          [...]

        </object-param>

      </init-params>

      [...]

    </component>

ldap.attribute.mapping maps your ldap to eXo. At first there are two main parameters to configure in it:

    <field name="baseURL"><string>dc=exoplatform,dc=org</string></field>

    <field name="ldapDescriptionAttr"><string>description</string></field>

- baseURL: root dn for eXo organizational entities. This entry can't be created by eXo and must preexist in directory.

- ldapDescriptionAttr (since core 2.2+) : Name of a common attribute that will be used as description for groups and membership types.

### Note

(since core 2.2+) : Name of a common attribute that will be used as description for groups and membership types.

Other parameters are discussed in the following sections.

##### Users

###### Main parameters

Here are the main parameters to map eXo users to your directory :

    <field name="userURL"><string>ou=users,ou=portal,dc=exoplatform,dc=org</string></field>

    <field name="userObjectClassFilter"><string>objectClass=person</string></field>

    <field name="userLDAPClasses"><string>top,person,organizationalPerson,inetOrgPerson</string></field>

- userURL : base dn for users. Users are created in a flat structure under this base with a dn of the form: ldap.userDN.key=username,userURL

Example :

    uid=john,cn=People,o=MyCompany,c=com

However, if users exist deeply under userURL, eXo will be able to retrieve them.

Example :

    uid=tom,ou=France,ou=EMEA,cn=People,o=MyCompany,c=com

- userObjectClassFilter: Filter used under userURL branch to distinguish eXo user entries from others.

Example : john and tom will be recognized as valid eXo users but EMEA and France entries will be ignored in the following subtree :

    uid=john,cn=People,o=MyCompany,c=com
      objectClass: person
      …
    ou=EMEA,cn=People,o=MyCompany,c=com
      objectClass: organizationalUnit
      …
        ou=France,ou=EMEA,cn=People,o=MyCompany,c=com
          objectClass: organizationalUnit
          …
            uid=tom,ou=EMEA,cn=People,o=MyCompany,c=com
              objectClass: person
              …

- userLDAPClasses : comma separated list of classes used for user creation.

When creating a new user, an entry will be created with the given objectClass attributes. The classes must at least define cn and any attribute refernced in the user mapping.

Example : Adding the user Marry Simons could produce :

    uid=marry,cn=users,ou=portal,dc=exoplatform,dc=org
      objectclass: top
      objectClass: person
      objectClass: organizationalPerson
      objectClass: inetOrgPerson
      …

###### User mapping

The following parameters maps ldap attributes to eXo User java objects attributes.

    <field name="userUsernameAttr"><string>uid</string></field>

    <field name="userPassword"><string>userPassword</string></field>

    <field name="userFirstNameAttr"><string>givenName</string></field>

    <field name="userLastNameAttr"><string>sn</string></field>

    <field name="userDisplayNameAttr"><string>displayName</string></field>

    <field name="userMailAttr"><string>mail</string></field>

- userUsernameAttr: username (login)

- userPassword: password (used when portal authentication is done by eXo login module)

- userFirstNameAttr: firstname

- userLastNameAttr: lastname

- userDisplayNameAttr: displayed name

- userMailAttr: email address

Example : In the previous example, user Marry Simons could produce :

    uid=marry,cn=users,ou=portal,dc=exoplatform,dc=org
      objectclass: top
      objectClass: person
      objectClass: organizationalPerson
      objectClass: inetOrgPerson
      …

##### Groups

eXo groups can be mapped to organizational or applicative groups defined in your directory.

    <field name="groupsURL"><string>ou=groups,ou=portal,dc=exoplatform,dc=org</string></field>

    <field name="groupLDAPClasses"><string>top,organizationalUnit</string></field>

    <field name="groupObjectClassFilter"><string>objectClass=organizationalUnit</string></field>

- groupsURL : base dn for eXo groups

Groups can be structured hierarchically under groupsURL.

Example: Groups communication, communication/marketing and communication/press would map to :

    ou=communication,ou=groups,ou=portal,dc=exoplatform,dc=org
    …
      ou=marketing,ou=communication,ou=groups,ou=portal,dc=exoplatform,dc=org
      …
      ou=press,ou=communication,ou=groups,ou=portal,dc=exoplatform,dc=org
      …

- groupLDAPClasses: comma separated list of classes used for group creation.

When creating a new group, an entry will be created with the given objectClass attributes. The classes must define at least the required attributes: ou, description and l.

### Note

l attribute corresponds to the City property in OU property editor

Example : Adding the group human-resources could produce:

    ou=human-resources,ou=groups,ou=portal,dc=exoplatform,dc=org
      objectclass: top
      objectClass: organizationalunit
      ou: human-resources
      description: The human resources department
      l: Human Resources
      …

- groupObjectClassFilter: filter used under groupsURL branch to distinguish eXo groups from other entries. You can also use a complex filter if you need.

Example : groups WebDesign, WebDesign/Graphists and Sales could be retrieved in :

    l=Paris,dc=sites,dc=mycompany,dc=com
      …
      ou=WebDesign,l=Paris,dc=sites,dc=mycompany,dc=com
      …
        ou=Graphists,WebDesign,l=Paris,dc=sites,dc=mycompany,dc=com
        …
    l=London,dc=sites,dc=mycompany,dc=com
      …
      ou=Sales,l=London,dc=sites,dc=mycompany,dc=com
      …

##### Membership Types

Membership types are the possible roles that can be assigned to users in groups.

    <field name="membershipTypeURL"><string>ou=memberships,ou=portal,dc=exoplatform,dc=org</string></field>

    <field name="membershipTypeLDAPClasses"><string>top,organizationalRole</string></field>

    <field name="membershipTypeNameAttr"><string>cn</string></field>

- membershipTypeURL : base dn for membership types storage.

eXo stores membership types in a flat structure under membershipTypeURL.

Example : Roles manager, user, admin and editor could by defined by the subtree :

    ou=roles,ou=portal,dc=exoplatform,dc=org
    …
      cn=manager,ou=roles,ou=portal,dc=exoplatform,dc=org
      …
      cn=user,ou=roles,ou=portal,dc=exoplatform,dc=org
      …
      cn=admin,ou=roles,ou=portal,dc=exoplatform,dc=org
      …
      cn=editor,ou=roles,ou=portal,dc=exoplatform,dc=org
      …

- membershipTypeLDAPClasses: comma separated list of classes for membership types creation.

When creating a new membership type, an entry will be created with the given objectClass attributes. The classes must define the required attributes : description, cn

Example : Adding membership type validator would produce :

    cn=validator,ou=roles,ou=portal,dc=exoplatform,dc=org
      objectclass: top
      objectClass: organizationalRole
      …

- membershipTypeNameAttr : Attribute that will be used as the name of the role

Example : If membershipTypeNameAttr is 'cn', then role name is 'manager' for the following membership type entry :

    cn=manager,ou=roles,ou=portal,dc=exoplatform,dc=org </pre>

##### Memberships

Memberships are used to assign a role within a group. They are entries that are placed under the group entry of their scope group. Users in this role are defined as attributes of the membership entry.

Example: To designate tom as the manager of the group human-resources:

    ou=human-resources,ou=groups,ou=portal,dc=exoplatform,dc=org
      …
      cn=manager,ou=human-resources,ou=groups,ou=portal,dc=exoplatform,dc=org
        member: uid=tom,ou=users,ou=portal,dc=exoplatform,dc=org
        …

The parameters to configure memberships are:

    <field name="membershipLDAPClasses"><string>top,groupOfNames</string></field>

    <field name="membershipTypeMemberValue"><string>member</string></field>

    <field name="membershipTypeRoleNameAttr"><string>cn</string></field>

    <field name="membershipTypeObjectClassFilter"><string>objectClass=organizationalRole</string></field>

- membershipLDAPClasses : comma separated list of classes used to create memberships.

When creating a new membership, an entry will be created with the given objectClass attributes. The classes must at least define the attribute designated by membershipTypeMemberValue.

Example : Adding membership validator would produce :

    cn=validator,ou=human-resources,ou=groups,ou=portal,dc=exoplatform,dc=org
      objectclass: top
      objectClass: groupOfNames
      …

<pre> cn=validator,ou=human-resources,ou=groups,ou=portal,dc=exoplatform,dc=org objectclass: top objectClass: groupOfNames ... </pre>

- membershipTypeMemberValue: Multivalued attribute used in memberships to reference users that have the role in the group.

Values should be a user dn.

Example: james and root have admin role within the group human-resources, would give:

    cn=admin,ou=human-resources,ou=groups,ou=portal,dc=exoplatform,dc=org
      member: cn=james,ou=users,ou=portal,dc=exoplatform,dc=org
      member: cn=root,ou=users,ou=portal,dc=exoplatform,dc=org
      …

- membershipTypeRoleNameAttr: Attribute of the membership entry whose value references the membership type.

Example : In the following membership entry:

<pre> cn=manager,ou=human-resources,ou=groups,ou=portal,dc=exoplatform,dc=org </pre>

'cn' attribute is used to designate the 'manager' membership type. Which could also be said : The name of the role is given by 'cn' the attribute.

- membershipTypeObjectClassFilter : Filter used to distinguish membership entries under groups.

You can use rather complex filters.

Example: Here is a filter we used for a customer that needed to trigger a dynlist overlay on openldap.

    (&amp;(objectClass=ExoMembership)(membershipURL=*))

Note: Pay attention to the xml escaping of the '&' (and) operator

##### User Profiles

eXo User profiles also have entries in the ldap but the actual storage is still done with the hibernate service. You will need the following parameters:

    <field name="profileURL"><string>ou=profiles,ou=portal,dc=exoplatform,dc=org</string></field>

    <field name="profileLDAPClasses"><string>top,organizationalPerson</string></field>

- profileURL: base dn to store user profiles

- profileLDAPClasses: Classes used to when creating user profiles

### 3.9.3. Advanced topics

#### Automatic directory population

At startup, eXo can populate the organization model based on

eXo organizational model has User,Group,Membership and Profile entities. For each, we define a base dn that should be below baseURL. At startup, if one of userURL, groupsURL, membershipTypeURL or profileURL does not exist fully, eXo will attempt to create the missing subtree by parsing the dn and creating entries on-the-fly. To determine the classes of the created entries, the following rules are applied :

- ou=... : objectClass=top,objectClass=organizationalUnit

- cn=... : objectClass=top,objectClass=organizationalRole

- c=... : objectClass=country

- o=... : objectClass=organization

- dc=.. : objectClass=top,objectClass=dcObject,objectClass=organization

Example:

If baseURL is o=MyCompany,c=com and groupsURL is dc=groups,cn=Extranet,c=France,ou=EMEA,o=MyCompany,c=com then, the following subtree will be created :

    ou=EMEA,o=MyCompany,c=com
      objectClass: top
      objectClass: organizationalUnit
      …
        c=France,ou=EMEA,o=MyCompany,c=com
          objectClass: top
          objectClass: country
          …
          cn=Extranet,c=France,ou=EMEA,o=MyCompany,c=com
            objectClass: top
            objectClass: organizationalRole
            …
            dc=groups,cn=Extranet,c=France,ou=EMEA,o=MyCompany,c=com
              objectClass: top
              objectClass: dcObject
              objectClass: organization
              …

#### Active Directory sample configuration

Here is an alternative configuration for active directory that you can find in activedirectory-configuration.xml

### Note

There is a microsoft limitation: password can't be set in AD via unsecured connection you have to use the ldaps protocol

here is how to use LDAPS protocol with Active Directory :

    1 setup AD to use SSL:

        * add Active Directory Certificate Services role
        * install right certificate for DC machine

    2 enable Java VM to use certificate from AD:

        * import root CA used in AD, to keystore, something like

          keytool -importcert -file 2008.cer -keypass changeit -keystore /home/user/java/jdk1.6/jre/lib/security/cacerts

        * set java options

          JAVA_OPTS="${JAVA_OPTS} -Djavax.net.ssl.trustStorePassword=changeit -Djavax.net.ssl.trustStore=/home/user/java/jdk1.6/jre/lib/security/cacerts"

#### OpenLDAP dynlist overlays

If you use OpenLDAP, you may want to use the overlays. Here is how you can use the dynlist overlay to have memberships dynamically populated.

The main idea is to have your memberships populated dynamically by an ldap query. Thus, you no longer have to maintain manually the roles on users.

To configure the dynlist, add the following to your slapd.conf :

    dynlist-attrset         ExoMembership membershipURL member

This snipet means : On entries that have ExoMembership class, use the URL defined in the value of attribute membershipURL as a query and populate results under the multivalues attribute member.

Now let's declare the corresponding schema (replace XXXXX to adapt to your own IANA code):

    attributeType ( 1.3.6.1.4.1.XXXXX.1.59 NAME 'membershipURL' SUP memberURL )

membershipURL inherits from memberURL.

    objectClass ( 1.3.6.1.4.1.XXXXX.2.12  NAME 'ExoMembership' SUP top MUST ( cn ) MAY (membershipURL $ member $ description ) )

ExoMembership must define cn and can have attributes :

- membershipURL: trigger for the dynlist

- member : attribute populated by the dynlist

- description : used by eXo for display

    # the TestGroup group
    dn: ou=testgroup,ou=groups,ou=portal,o=MyCompany,c=com
    objectClass: top
    objectClass: organizationalUnit
    ou: testgroup
    l: TestGroup
    description: the Test Group

On this group, we can bind an eXo membership where the overlay will occur:

    # the manager membership on group TestGroup
    dn: cn=manager, ou=TestGroup,ou=groups,ou=portal,o=MyCompany,c=com
    objectClass: top
    objectClass: ExoMembership
    membershipURL: ldap:///ou=users,ou=portal,o=MyCompany,c=com??sub?(uid=*)
    cn: manager

This dynlist assigns the role manager:/testgroup to any user.

## 3.10. Organization Service TCK tests configuration

The process of launching the Organization Service TCK tests against your Organization Service is quite easy. For instance you may add TCK tests to your maven project and launch them during unit testing phase. To do that you need to complete the next two steps:

- Configure your maven pom.xml file

- Configure standalone container and Organization Service

  ### Note

  If you need more profound information you can find Organization Service TCK test sources at svn

### 3.10.1. Maven pom.xml file configuration

Organization Service TCK tests are available as a separate maven artifact, so the first thing you need to do is to add this artifact as a dependency to your pom.xml file

          <dependency>

            <groupId>org.exoplatform.core</groupId>

            <artifactId>exo.core.component.organization.tests</artifactId>

            <version>2.4.3-GA</version>

            <classifier>sources</classifier>

            <scope>test</scope>

          </dependency>

You will also need to unpack tests as they are archieved within jar file. For this purpose you may use maven-dependency-plugin

         <plugin>

             <groupId>org.apache.maven.plugins</groupId>

             <artifactId>maven-dependency-plugin</artifactId>

             <executions>

                <execution>

                   <id>unpack</id>

                   <phase>generate-test-sources</phase>

                   <goals>

                      <goal>unpack</goal>

                   </goals>

                   <configuration>

                      <artifactItems>

                         <artifactItem>

                            <groupId>org.exoplatform.core</groupId>

                            <artifactId>exo.core.component.organization.tests</artifactId>

                            <classifier>sources</classifier>

                            <type>jar</type>

                            <overWrite>false</overWrite>

                         </artifactItem>

                      </artifactItems>

                      <outputDirectory>${project.build.directory}/org-service-tck-tests</outputDirectory>

                   </configuration>

                </execution>

             </executions>

          </plugin>

### Note

Remember the value of outputDirectory parameter as you will need it later.

After you have unpacked the tests you need to add the tests sources and resources, use build-helper-maven-plugin

          <plugin>

             <groupId>org.codehaus.mojo</groupId>

             <artifactId>build-helper-maven-plugin</artifactId>

             <version>1.3</version>

             <executions>

                <execution>

                   <id>add-test-resource</id>

                   <phase>generate-test-sources</phase>

                   <goals>

                      <goal>add-test-resource</goal>

                   </goals>

                   <configuration>

                      <resources>

                         <resource>

                            <directory>${project.build.directory}/org-service-tck-tests</directory>

                         </resource>

                      </resources>

                   </configuration>

                </execution>

                <execution>

                   <id>add-test-source</id>

                   <phase>generate-test-sources</phase>

                   <goals>

                      <goal>add-test-source</goal>

                   </goals>

                   <configuration>

                      <sources>

                         <source>${project.build.directory}/org-service-tck-tests</source>

                      </sources>

                   </configuration>

                </execution>

             </executions>

          </plugin>

### Note

directory and source parameter should point to the location you've specified in outputDirectory parameter just above.

You also need to include all TCK tests using maven-surefire-plugin

          <plugin>

            <groupId>org.apache.maven.plugins</groupId>

            <artifactId>maven-surefire-plugin</artifactId>

            <configuration>

              ...

              <includes>

                  <include>org/exoplatform/services/tck/organization/Test*.java</include>

              </includes>

              ...

            </configuration>

          </plugin>

As a result you should have TCK being launched during your next maven clean install. Example of configured pom.xml file you can find at svn server

### 3.10.2. Standalone container and Organization Service configuration

TCK tests use standalone container, so to launch TCK tests propertly you will also need to add Organization Service as a standalone component. For that purpose use configuration file, which is to be located in 'src/test/java/conf/standalone/test-configuration.xml' by default, but its location can be changed by system property called orgservice.test.configuration.file. Add your Organization Service configuration with all needed components there.

In addition you need to populate your Organization Service with organization data (TCK tests are designed to use this data):

          <external-component-plugins>

            <target-component>org.exoplatform.services.organization.OrganizationService</target-component>

            <component-plugin>

              <name>init.service.listener</name>

              <set-method>addListenerPlugin</set-method>

              <type>org.exoplatform.services.organization.OrganizationDatabaseInitializer</type>

              <description>this listener populate organization data for the first launch</description>

              <init-params>

                <value-param>

                  <name>checkDatabaseAlgorithm</name>

                  <description>check database</description>

                  <value>entry</value>

                </value-param>

                <value-param>

                  <name>printInformation</name>

                  <description>Print information init database</description>

                  <value>false</value>

                </value-param>

                <object-param>

Ultimately you will have a configuration file which determines standalone container and consists of Organization Service configuration and initialization data. You can find prepared test-configuration.xml file at svn

## 3.11. Tika Document Reader Service

DocumentReaderService provides API to retrieve DocumentReader by mimetype.

DocumentReader lets the user fetch content of document as String or, in case of TikaDocumentReader, as Reader.

### 3.11.1. Architecture

Basicaly, DocumentReaderService is a container for all registered DocumentReaders. So, you can register DocumentReader (method addDocumentReader(ComponentPlugin reader)) and fetch DocumentReader by mimeType (method getDocumentReader(String mimeType)).

TikaDocumentReaderServiceImpl extends DocumentReaderService with simple goal - read Tika configuration and lazy register each Tika Parser as TikaDocumentReader.

### Note

By default, all Tikas Parsers are not registered in readers <mimetype, DocumentReader> map. When user tries to fetch a DocumentReader by unknown mimetype. Than TikaDocumentReaderService checks tika configuration, and register a new mimetype-DocumentReader pair.

### 3.11.2. Configuration

How TikaDocumentReaderService Impl configuration looks like:

          <type>org.exoplatform.services.document.impl.tika.TikaDocumentReaderServiceImpl</type>

### 3.11.3. Old-style DocumentReaders and Tika Parsers

As you see configuration above, there is both old-style DocumentReaders and new Tika parsers registered.

But MSWordDocumentReader and org.apache.tika.parser.microsoft.OfficeParser both refer to same "application/msword" mimetype, exclaims attentive reader. And he is right. But only one DocumentReader will be fetched.

Old-style DocumentReader registered in configuration become registered into DocumentReaderService. So, mimetypes that is supported by those DocumentReaders will have a registered pair, and user will always fetch this DocumentReaders with getDocumentReader(..) method. Tika configuration will be checked for Parsers only if there is no already registered DocumentReader.

#### How to make and register own DocumentReader

You can make you own DocumentReader in two ways.

Old-Style Document Reader:

- extend BaseDocumentReader

    public class MyDocumentReader extends BaseDocumentReader

    {

       public String[] getMimeTypes()

       {

          return new String[]{"mymimetype"};

       }

       ...

    }

- register it as component-plugin

    <component-plugin>

       <name>my.DocumentReader</name>

       <set-method>addDocumentReader</set-method>

       <type>com.mycompany.document.MyDocumentReader</type>

       <description>to read my own file format</description>

    </component-plugin>

Tika Parser:

- implement Parser

    public class MyParser implements Parser

    {

       ...

    }

- register it in tika-config.xml

     <parser name="parse-mydocument" class="com.mycompany.document.MyParser">

          <mime>mymimetype</mime>

     </parser>

### 3.11.4. TikaDocumentReader features and notes

TikaDocumentReader features and notes:

- TikaDocumentReader may return document contant as Reader object. Old-Style DocumentReader does not;

- TikaDocumentReader do not detects document mimetipe. You will get exact parser as configured in tika-config;

- All readers methods closes InputStream at final.

## 3.12. Digest Authentication

Digest access authentication is one of the agreed methods a web server can use to negotiate credentials with a web user's browser. It uses encryption to send the password over the network which is safer than the Basic access authentication that sends plaintext.

Technically digest authentication is an application of MD5 cryptographic hashing with usage of nonce values to discourage cryptanalysis. It uses the HTTP protocol.

### 3.12.1. Server configuration

To configure you server to use DIGEST authentication we need to edit serverside JAAS module implementation configuration file.

#### Tomcat Server configuration

You need to fulfill a couple of steps. Firstly change login configuration:

Edit config file located here: exo-tomcat/webapps/rest.war/WEB-INF/web.xml

Replace

    <login-config>
      <auth-method>BASIC</auth-method>
      <realm-name>eXo REST services</realm-name>
    </login-config>

for

    <login-config>
      <auth-method>DIGEST</auth-method>
      <realm-name>eXo REST services</realm-name>
    </login-config>

More information about tomcat configuration can be found at Apache Tomcat Configuration Reference.

Secondly you also need to specify new login module for JAAS:

Edit config file located here: exo-tomcat/conf/jaas.conf

Replace

    exo-domain {
      org.exoplatform.services.security.j2ee.TomcatLoginModule required;
    };

for

    exo-domain {
      org.exoplatform.services.security.j2ee.DigestAuthenticationTomcatLoginModule required;
    };

#### Jetty server configuration

You need to fulfill a couple of steps. Firstly change login configuration:

Edit config file located here: exo-jetty/webapps/rest.war/WEB-INF/web.xml

Replace

    <login-config>
      <auth-method>BASIC</auth-method>
      <realm-name>eXo REST services</realm-name>
    </login-config>

for

    <login-config>
      <auth-method>DIGEST</auth-method>
      <realm-name>eXo REST services</realm-name>
    </login-config>

Secondly you also need to specify new login module for JAAS:

Edit config file located here: exo-jetty/jaas.conf

Replace

    exo-domain {
      org.exoplatform.services.security.j2ee.JettyLoginModule required;
    };

for

    exo-domain {
      org.exoplatform.services.security.j2ee.DigestAuthenticationJettyLoginModule required;
    };

#### JBoss server configuration

Edit config file located here: exo-jboss/server/default/deploy/exo.jcr.ear.ear/rest.war/WEB-INF/web.xml

Replace

    <login-config>
      <auth-method>BASIC</auth-method>
      <realm-name>eXo REST services</realm-name>
    </login-config>

for

    <login-config>
      <auth-method>DIGEST</auth-method>
      <realm-name>eXo REST services</realm-name>
    </login-confi

You also need to edit login configuration file located here: exo-jboss/server/default/conf/login-config.xml

    <application-policy name="exo-domain">
        <authentication>
            <login-module code="org.exoplatform.services.security.j2ee.DigestAuthenticationJbossLoginModule"
                          flag="required">
                <module-option name="usersProperties">props/jmx-console-users.properties</module-option>
                <module-option name="rolesProperties">props/jmx-console-roles.properties</module-option>
                <module-option name="hashAlgorithm">MD5</module-option>
                <module-option name="hashEncoding">rfc2617</module-option>
                <module-option name="hashUserPassword">false</module-option>
                <module-option name="hashStorePassword">true</module-option>
                <module-option name="passwordIsA1Hash">true</module-option>
                <module-option name="storeDigestCallback">
                    org.jboss.security.auth.spi.RFC2617Digest
                </module-option>
            </login-module>
        </authentication>
    </application-policy>

You probably should define users.properties and role.properties according to your own needs.

More information about jboss server Digest authentication configuration can be found at JBoss guide chapter.

### 3.12.2. OrganizationService implementation requirements

To make your own `org.exoplatform.services.organization.OrganizationService` implementation able to use DIGEST authentication you need to make your UserHandler implementation also implement `org.exoplatform.services.organization.DigestAuthenticator` interface which provide more flexible authenticate method. As it is called from `org.exoplatform.services.organization.auth.OrganizationAuthenticatorImpl` it receive a `org.exoplatform.services.security.Credential` instances, you can get more information from `org.exoplatform.services.security.PasswordCredential.getPasswordContext()`. It can be used to calculate md5 digest of original password to compare it with recieved from clientside.
