Help: .net soap client sees empty responses from Axis

[jennifer.perkins]

I've seen a couple posts by people having similar problems, but the
suggested solutions I've tried so far haven't worked.

I'm using a SOAP client in VB.Net (constructed by wsdl.exe) and the
third party web service it's consuming is served by Axis. The request
messages my client sends are processed fine by the server, and the SOAP
response is making its way to my client - but when .Net finishes
processing the message I end up with an empty result data structure,
even though the information is in the response message.

Also, the web service is using literal/wrapped wsdl.

Any help or suggestions would be appreciated. Thanks,

Jennifer

The wsdl is:
