Hi, I am facing similar problem , JBoss version is 4.2.2 OS -WIN XP, JDK 1.6 . I have gone through the Jira postings, followed as advised , that is copying jboss-jaxrpc.jar, jboss-jaxws.jar, jboss-saaj.jar to JBOSS_HOME/lib/endorsed from JBOSS_HOME/server/default/lib and JBOSS_HOME/client/lib It did not work.
