2.5.2. Portal Navigation

The portal navigation incorporates the pages that can be accessed even when the user is not logged in assuming the applicable permissions allow the public access). For example, several portal navigations are used when a company owns multiple trademarks, and sets up a website for each of them.

The classic portal is configured by four XML files in the 02portal.war:/WEB-INF/conf/portal/portal/classic directory:

portal.xml

This file describes the layout and portlets that will be shown on all pages. The layout usually contains the banner, footer, menu and breadcrumbs portlets. GateIn 3.2 is extremely configurable as every view element (even the banner and footer) is a portlet.

      </portlet-application>

   </portal-layout>
   
</portal-config>

It is also possible to apply a nested container that can also contain portlets. Row, column or tab containers are then responsible for the layout of their child portlets.

Each application references a portlet using the id portal#{portalName}:/{portletWarName}/{portletName}/{uniqueId}

Use the page-body tag to define where GateIn 3.2 should render the current page.

The defined classic portal is accessible to "Everyone" (at /portal/public/classic) but only members of the group /platform/administrators can edit it.

navigation.xml

This file defines all the navigation nodes of the portal. The syntax is simple using the nested node tags. Each node refers to a page defined in the pages.xml file (explained next).

If the administrator want to create node labels for each language, they will have to use xml:lang attribute in the label tag with value of xml:lang is the relevant locale.

Otherwise, if they want the node label is localized by resource bundle files, the #{...} syntax will be used, the enclosed property name serves as a key that is automatically passed to the internationalization mechanism. Thus the emphasis property name is replaced by a localized value taken from the associated properties file matching the current locale.

For example:

<node-navigation 
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://www.gatein.org/xml/ns/gatein_objects_1_2 http://www.gatein.org/xml/ns/gatein_objects_1_2"
   xmlns="http://www.gatein.org/xml/ns/gatein_objects_1_2">
   <priority>1</priority>
   <page-nodes>
      <node>
         <name>home</name>
         <label xml:lang="en">Home</label>
         <page-reference>portal::classic::homepage</page-reference>
      </node>
      <node>
         <name>sitemap</name>
         <label xml:lang="en">SiteMap</label>
         <visibility>DISPLAYED</visibility>
         <page-reference>portal::classic::sitemap</page-reference>
      </node>
      ..........
   </page-nodes>
</node-navigation>

This navigation tree can have multiple views inside portlets (such as the breadcrumbs portlet) that render the current view node, the site map or the menu portlets.

pages.xml

This configuration file structure is very similar to portal.xml and it can also contain container tags. Each application can decide whether to render the portlet border, the window state, the icons or portlet's mode.
