Gunter, I appreciate that you used FR to find the indication of the call wanting an int, and it’s great that Mark shared the javacast, but since you’re still having problems applying those discoveries, would you please use one of the tools (whether SOAPUI or the soapclient svc) to let the WEB SERVICE tell you FOR SURE what datatype it expects for userid? 
FWIW, I had been holding off suggesting javacast simply because the FIRST focus is to find WHAT datatype it expects. You seem to be dancing all around this simple suggestion I have made from the very first reply yesterday. I don’t understand why.
Was it perhaps challenging for you to find what the tools were reporting as the datatype? Again, since we can’t access the web service remotely, we can’t tell “for you”. Someone may propose that if you share the WSDL, we could look directly at it or point our own wsdl browsing tool at that. But note that often the wsdl will include references to still other wsdl which is pulled in dynamically, so we’d again not have access to that if it’s also not publicly accessible.
Bottom line: does your view of the wsdl or use of either tool show you WHAT datatype is expected for setuserid? Since that seems to be a setter that’s called implicitly, it may not appear in the definition of that getXTMInfo method you’re actually calling, but there should be definition SOMEWHERE in the wsdl that would define it.
As always, just trying to help.
