I think the request message you're sending is not valid if you use the Document / Literal style, while it is good for RPC/Lit. RPC/encoded is definitely bad, rpc/lit can be used instead. Anyway, if you need/want to use doc/lit, I would suggest to copy from a soap request created by another ws stack (jbossws itself, axis or tools like soapui, etc.) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4104596#...
