I'm not bundling with the jsf-impl.jar and jsf-api.jar. Only libraries bundled are: portlet-api-1.0.jar ajax-wrapper-comp.jar jsf-portlet.jar (the portlet brigde I referred to earlier in this thread) Can I send you the whole war file so that you can take a look at it? Some general questions: 1. Which JSF implementation do you recommend? Since JBoss 4.2.0 bundles with the sun JSF 1.2 RI, does it mean that JBoss thinks that's a better implementation than MyFaces? 2. Is it correct that I'm supposed to declare com.sun.faces.portlet.FacesPortlet as portlet-class in portlet.xml, or am I supposed to declare the class that I use that extends the com.sun.faces.portlet.FacesPortlet class? I have a class com.test.Search which extends the FacesPortlet. The war file that I deployed on JBoss 4.2.0 runs perfectly in the Open Source Portlet Container used in Netbeans.
