调用Web服务并为响应对象获取null

Question

I am working with a 3rd party web service which is written in Java/Axis. I have not worked much with WCF so I am trying to feel my way through this. I was able to generate the class from the wsdl and using Fiddler I am able to see the call being made to the service, and a response being returned. But in my code, my response is empty and I am not sure why I am not seeing the response. I did read one post about the namespace, and tried to update it, but no luck. Below is the generated class, the wsdl and the response from the web service. Is there an issue with the auto generated class? Why is my response not being consumed by the C# code?

This is the generated class. I only included the methods I am calling since this file is over 5000 lines and most of it will not be used by us.

        }
    }
}

Here is the URL to the WSDL. Not sure if this is accessible outside our network.

http://sdrsafposent1d:8081/axis/services/grandeFacade?wsdl

And here is the response Fiddler captured. My other question is with the response I see there is a Java Exception and some ugly jibberish afterwards. Can this be causing the issue with the response not being consumed?

Here is the block of code that I where I am making the call and capturing the response.

grandeFacadeService grandeFacadeService serv = new grandeFacadeService();
WebServiceResp response = serv.EnterpriseObjects(enterpriseObjValueslist);
wsResponse[] responseArray= response.wsResponse;

Answer 1

The issue turned out to be the xml itself. If you look at the xml half way down it looks like their response was decoding the greater than and less than.
