Invoking WebMethods WebService Issue

[Arun Kumar]

Hi All,

I'm trying to create a .NET client to consume a webMethods web service.
Based on the wsdl file given by you I've generated a .NET proxy class using
the .NET WSDL.EXE. The proxy class appears to send a valid request because
webMethods sends back a valid response. However, when the proxy class calls
Invoke(), it returns the object[] results of the correct length i.e. 2 but
with each element null. The return parameters are just strings. There are no
exceptions. Why are th return parameters null?

Thanx & Regds,

Arun

We ran into this same issue. We had to new each string on the server side for it not to come back null on the client side. If we just had str = "cat" it wouldn't work. Don't know why...

What are the intput/ouput types? Is this WSE related or ASMX Only?
