You can just look at the Test portlet (came with jboss-portal itself). The actuall navigation was shown in the CatelogPortlet(which will comes with the jboss-portal).
Basically you need to define your *-object.xml such that it has the embedead tages(See the template below).
<deployments> <deployment> <if-exists>overwrite</if-exists> <parent-ref>default</parent-ref> <page> <page-name> ROOT_NAV_1</page-name> <window> </window> <page> <page-name>SUB_NAV_1</page-name> </page> <page> <page-name>SUB_NAV_2</page-name> </page> </page> </deployment> </deployments>
I used to get the navigation as was implemented in the Test Portlet and able to display these links as navigation items in the lefthandseide(in CatelogPortlet) in my portal based on the Roles.
Thanks and Regards
