Hi Vincent, No, I haven't solved this yet. I was working on some other stuff hoping that I'd get a hint from the forum. But soon I have to come up with a solution so I guess the only thing left to do is to get down and dirty with the JBossWS source code... I think the documentation on JBossWS client configuration (both for the stub objects and for standard-jaxws-client-config.xml) is very poor so I put another forum post for this (http://www.jboss.com/index.html?module=bb&op=viewtopic&t=128758) but that didn't do much good either. When I solve this I'll share it here and if you beat me to it I'd appreciate if you did the same. Cheers, Mattias View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4125237#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
