The return type of that method is xsd:integer, which is mapped to String
by to wsdl tool. Notice that xsd:integer is not the same as xsd:int,
which is mapped to Int32. MS.NET does the same.

The error you are getting is an error reported by the server. You should
debug the server and see why it is throwing that error.
