UserBean only contains Strings.
The WEB Service runs to completion on the server when its invoked. But I
get the cast exception on the client. In this case it's a Java client
that was generated with WSDL2Java.
It actually fails in the SoapBindingStub on the invoke.
java.lang.Object _resp = _call.invoke(new
java.lang.Object[] {});

Looks ok. If it compiles and runs ok "without" Axis and SOAP it should
run ok with Axis as well.
This is of course assuming that UserBean only contains allowed
attributes as mentioned in the earlier mail, or at least only beans
which in turn only contain allowed attributes.
Keep that link I sent you handy, it's quite useful, I still refer to it
from time to time. :)
