.NET and axis Interoperability issues

[Jeevak Kasarkod <Je...@sivault.com>]

Hi,

 

I have built a C# client which invokes an axis web service. The
call is made through an http proxy which is basically a soap monitor.
I have a log of the requests and responses and all of them are legal
but my .NET c# client is unable to reference the object.
I get the following error
Object reference not set to an instance of an object

On my list of watch variables the returned object shows up as Null
even though the soap monitor shows a response from the service. 


The stack trace is
[NullReferenceException: Object reference not set to an instance of an
object.]
 SASTest.WebForm1.Button1_Click(Object sender, EventArgs e) in
c:\inetpub\wwwroot\sastest\webform1.aspx.cs:66
 System.Web.UI.WebControls.Button.OnClick(EventArgs e)
 
System.Web.UI.WebControls.Button.System.Web.UI.IPostBackEventHandler.Rai
sePostBackEvent(String
eventArgument)
 System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler
sourceControl, String eventArgument)
 System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData)
 System.Web.UI.Page.ProcessRequestMain()



I have pasted the wsdl below
