OK, you might evaluate using a little workaround, i.e. having a jaxws ejb3 endpoint in front of your ejb2 and delegating to it. Btw I don't see anything obviously wrong with your wsdl/mapping/file; you might try using jbossws wstool to generate jax-rpc artifacts and compare them with the ones you get from wscompile. In case you still have problems and upgrading to jaxws (even using the suggested workaround) is not an option, you could create a jira issue attaching a small application affected by this problem. Anyway please consider that actually jbossws team main focus is on the jax-ws issues. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4092103#...
