In your web.xml, you are referring to the initializer for the JSF RI implementation. The version of JBoss you are using comes with MyFaces pre-installed. The easiest thing for you to do is probably to load the initializer for MyFaces instead. See http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossFaces and http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossWithIntegratedMyFaces Put this in your web.xml: <listener> | <listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class> | </listener> Stan View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4021262#...
