Call thirty party java web service but always return null

Question

hi
I call a java web service in my application visual studio 2008 c#, but always return NULL.
I used Tool Fiddler to monitor the traffic between my client and the web service server, it showed the return is not Null.
Here is my code, please see if anything I do wrong.

using System.Web.Services;

Hi;
I used Fiddler to monitor the process, and it showed the request sent thru web service worked and returned a value, but in my .Net application the return captured as NULL. Could you please look into the code above and the result from Filddler and see if
you can help.
thank you.
