Hi Kalvin, ok.. sorry.. mistake was mine.. I'm not sure if wstools supports this currently, the coming JAX-WS 2.0 compatible JBossWS 2.0 uses JAXB for databinding which probably supports your scenario.. but I'm not sure on any of those claims ;-).. try reposting your question in the JBossWS forum to see what "the experts" say.. Obviously, if it is supported by wstools, we will add a UI for it as well.. regards! /Ole View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3981645#...
