If you control the code for the .NET service and want it to interoperate
best with Apache SOAP, you need to use the SoapRpcService attribute on
the class. By default, a .NET WebService class uses document/literal
encoding. This is great for interoperation with other WSDL-based
implementations, but makes interoperation difficult (or impossible) for
SOAP implementations, like Apache SOAP, that are not WSDL-based.
The current build of Apache SOAP includes enough facilities for faking
document/literal that it can be used to interop with most .NET services,
but I still recommend using SoapRpcService for any .NET services you
write.
