There are some overridable components in eXo Collaboration so that you can control how these components work by implementing or extending default implementations and then reconfigure these new components in the configuration.xml file.
ContentDAO is an overridable component used in the Content application (or called RSS reader) of eXo Collaboration.
You can find the configuration file at WEB-INF/cs-extension/cs/content/content-service-configuration.xml with the declaration as below:
<component>
<key>org.exoplatform.content.service.ContentDAO</key>
<type>org.exoplatform.content.service.impl.ContentDAOImpl</type>
</component>
The example below is an example of plugin configuration:
<external-component-plugins>
<target-component>org.exoplatform.content.service.ContentDAO</target-component>
<component-plugin>
<name>rssreader.listener</name>
<set-method>addPlugin</set-method>
<type>org.exoplatform.content.service.RSSContentPlugin</type>
<description>rss reader plugin</description>
</component-plugin>
<component-plugin>
<name>description.listener</name>
<set-method>addPlugin</set-method>
<type>org.exoplatform.content.service.DescriptionPlugin</type>
<description>Description plugin</description>
</component-plugin>
</external-component-plugins>
ContactLifeCycle is an interface to extend the capabilities of eXo Platform. The ContactLifeCycle lets you be notified during the lifecycle of an address book's contact when a contact is added or modified.
An example of ContactLifeCycle has been implemented to integrate the Address Book application in the eXo Social's Spaces. See the following configuration at: ext/social-integration/src/main/resources/conf/portal/configuration.xml.
See the following example:
<external-component-plugins>
<target-component>org.exoplatform.contact.service.ContactService</target-component>
<component-plugin>
<name>ContactEventListener</name>
<set-method>addListenerPlugin</set-method>
<type>org.exoplatform.cs.ext.impl.ContactSpaceActivityPublisher</type>
</component-plugin>
</external-component-plugins>
Details: ContactSpaceActivityPublisher implements ContactLifeCycle. This implementation publishes activities in the space activity stream to notify of new and updated contacts in the space address book.
Transport is an overridable component used in the Chat application of eXo Collaboration.
This overridable component is used to help users add the protocol to the Chat application, such as: ICQ, YAHOO, MSN, XMPP, AIM, GTALk.
The Chat application of eXo Collaboration only uses the XMPP protocol that is implemented in the XMPPTransport object.
EventLifeCycle is an extension point used in the Calendar application of eXo Collaboration. You can find the configuration file of this component at: ext/social-integration/src/main/resources/conf/portal/configuration.xml.
See the following example:
<external-component-plugins>
<target-component>org.exoplatform.calendar.service.CalendarService</target-component>
<component-plugin>
<name>CalendarEventListener</name>
<set-method>addEventListenerPlugin</set-method>
<type>org.exoplatform.cs.ext.impl.CalendarSpaceActivityPublisher</type>
</component-plugin>
</external-component-plugins>
Details: CalendarSpaceActivityPublisher implements EventLifeCycle. It writes activities in the space activity stream when events or tasks are added/modified.
eXo Collaboration implements and provides many public REST APIS to help built-in applications, such as Calendar, Chat and Mail to communicate and transfer data with the server. By using these public REST APIs, extended or 3rd party applications can make use of this to develop cool web applications faster without much implementation.
The Calendar application of eXo Collaboration uses CalendarWebservice to provide all APIs for working with calendars, such as creating personal/group calendars, sharing calendars, managing events/tasks.
The REST API of Calendar portlet is exposed by org.exoplatform.services.cs.calendar.CalendarWebservice class.
| Service name | Service URL | Location | Description |
|---|---|---|---|
| CalendarWebservice | $portalname/$restcontextname/private/cs/calendar |
- Maven groupId: org.exoplatform.cs - ArtifactId: exo.cs.web.webservice | Call extended services of the Calendar application. |
Details:
$portalname: The name of the portal
$restcontextname: The context name of rest webapplication which is deployed to the "$portalname" portal.
Private: is optional and used for the protected access only. Such calls will require authentication.
APIs usage:
Use the following APIs to build all functions of the Calendar application:
