And you cant just start a project with Java 1.5 either, because then u cant use the annotation @Webservice (it conflicts somehow with rt.jar from Java 1.6). So I had to downlad and install Java 1.5 and then use this. Maybe this solution is trivial for experienced guys like u, but it sure wasnt for me. And I dont really understand why I have to do it this way. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4155515#...
