No, that would be absurd.

Your Java-ish error message basically says your SOAP::WSDL program generated something the server couldn't understand.

You need to turn tracing on, so you can see exactly what your program sends to the server (real XML).

Then you need to compare the XML sent to see how it differs from what the server expects, so you can figure out what SOAP::WSDL isn't translating (that pdf summary of the WSDL won't help ).
