Can you tell what are the list of required xml files ?
In 2.0 I have :
*-portal.xml *-pages.xml portlet.xml portlet-instances.xml portal-theme.xml portal-layout.xml jboss-portal.xml jboss-web.xml jboss-app.xml web.xml
*-objects is used with 2.2.0 and it replaces *-pages.xml and *-instances.xml used in 2.0.
