I figured out the problem even though the errors being thrown didn't really help. For some reason, if I start the process of calling my webserivce from a bean annotated as JMX component, the webservice call does not work. If I start the call from say a Servlet everything is fine. Not sure why I can't use a JMX component though. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4059380#...
