Yeah...Jeff Ortel is really good at working with WSDLs and spotting
where the fault lies (whether it be the programmer's fault for not
fully specifying what they need, or the WSDL's fault for not properly
specify all types or services ports, etc.).
For your log below, what WSDL are you using? From the log, it looks
like your WSDL defines stringArray, but then the service is returning
something unexpected. But I don't know anywhere near enough about SOAP
to provide an authoritative answer on that. Ask Jeff. :)
