A direct question: what does it means "ignoring invalid namespace mapping"? The server (Jboss 4.0.1, 4.0.2RC1, 4.0.2...) tells me so when i try to access a web service. The service works fine, everything is right, the answer that it returns is correct, I'm happy, but why do Jboss write that warning to the console?
You need to show us the stacktrace and (if applicable) the abstract contract (wsdl + schema) and the soap message.
