Hello, May be thats too late for you, but I think will help others. I faced similar situation. My guess was that the Jars in WEB-INF/lib were creating a conflict with the jars loaded by Jboss instance from server/lib directory. You can try removing the unwanted jars from WEB-INF/lib that are already present in JBoss lib directory.
