i try using thomahok only with jsf jars , i found the same exception.
wait your reply
From the stack trace, I see that you are indeed using the MyFaces Core JSF implementation. So I assume you are packaging myfaces-api.jar and myfaces-impl.jar in your WEB-INF/lib? For this you will need to put the WAR_BUNDLES_JSF_IMPL context param in your web.xml.
The next community release of AS6 will contain both Mojarra and MyFaces Core, so you won't need to bundle it with your WAR or set the context param. See the "JSF on AS6 Guide" for details.
