It works on was v6.1.0.7, ...but: - You have to put all your code in a war (we were not able to make it work by splitting the code between a war and an utility jar...if you know how to do, tell us please ) - You have to use MyFaces instead of the the JSF 1.1 implementation included with was v6.1. Search on "MyFaces" in the was support page and find the paper from IBM explaining how to make MyFaces work with was v6.1 - You must use PARENT_LAST on BOTH ear and war classloader amd put jboss* libs in ot WEB-INF/lib View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4045645#...
