Hello, I don't know exactly what's going on in your error, but anyway, it seem to be a problem of compatibility of this portlet bridge. You have examples of JSF portlet in the release of Jboss portal. look at portlet.xml files. I did my portlets like they were defined in 2.4.1 : the portlet that use JSF are declare with this : <portlet> | <portlet-name>MyJSFPortlet</portlet-name> | <portlet-class> | org.apache.myfaces.portlet.MyFacesGenericPortlet | </portlet-class> | .... | it uses the myfaces JSF portlet. may be in 2.6, the sun version is used (don't remember exaclty, but I saw something about that... will look later when working on that part...). anyway... first look at the portlets in the release, that use JSF and work. It should help you. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4059908#...
