[Axis 1] Webservice returns null in .NET client

[Pasquale Imbemba <p....@gmail.com>]

Hi,

I have a simple web service that exposes a method called concat. This method
takes a ConcatRequest object, which has two string fields. The result of
this method is the concatenation of the two fields.
A java client that consumes the webservice works well, i.e. the return
string is the concatenation of the two fields set in the ConcatRequest
object. In .NET instead, the  client calls the method, but null is returned.
I have check with tcpmon to see if the SOAP exchanges are ok.

I am using Axis 1 with Tomcat. I've designed the service with WTP in eclipse
and deployed using WSDD.

Any idea why the .NET client is not working?

Thanks
