See the instructions at the end of this wiki: http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossWithIntegratedMyFaces To switch to the RI, you may also need to delete temp directories such as server/default/tmp and server/default/work. And of course, you need to get rid of the MyFaces context listener in your web.xml. In short, if you completely get rid of MyFaces you will have no danger of executing MyFaces classes. You shouldn't need to extract the TLD into your WAR. The proper TLD's are packaged with the RI. JSF will discover them automatically. In JBoss 4.2 and JBoss 5.0, the RI is installed by default. http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossWithJSFCDDL Stan View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4018206#...
