C# response object contains null when calling Java Web Service

Question

I've been sent the following wsdl. I generated the C# proxy using wsdl.exe and also created my c# web page. Using Fiddler I have looked at the SOAP response and it contains data. Any guidance on what modification is needed in order to get the C# program to accept the SOAP response. Please excuse the formatting of the wsdl I was uncertain as to which format to use for best results.

Answer 1

Well, first of all, I would monitor your network traffic (HTTP) to ensure that something is being returned. If that is the case, I remember having problems with namespaces when calling Web Service from C# to Java and vice-versa. One of the sides had the namespace declaration, the other didn't, and one of the sides would think that it got no data because it was looking for something else.

This is a very generic explanation, but that was a long time ago. I remember that it was positively a cause of issues. You may have to use a different WS client to monitor a valid call, and then check what's different when you perform the call from the C# client.

Answer 2

If you use WebReferences, let check wsdl file to be sure targetNamespace and name space are same.

Hope this help!

Answer 3

I don't see a CreateMoveHistoryResponse definition in your soap response... Instead I see a ReturnMessage... and I believe there is the problem.

I see the <xsd:element name="CreateMoveHistoryResponse" type="tns:ReturnMessage" /> in your wsdl definition but I don't know why the wsdl.exe util don't generate the class of the correct type.

Hope this helps solving the issue...
