Given this very simple .NET web service in C#, can someone get a Java
client using Apache Axis to access it? I am trying at this moment to do
so.

using System.Collections;
using System.ComponentModel;

{

[SoapRpcService(RoutingStyle=SoapServiceRoutingStyle.SoapAction)]
public class SumService : System.Web.Services.WebService
{
public SumService()
{
//CODEGEN: This call is required by the ASP.NET
Web Services Designer
InitializeComponent();
}
#region Component Designer generated code
//Required by the Web Services Designer
private IContainer components = null;
/// <summary>
/// Required method for Designer support - do not modify

private void InitializeComponent()

/// <summary>
/// Clean up any resources being used.

protected override void Dispose( bool disposing )
{
if(disposing && components != null)
{
components.Dispose();
}
base.Dispose(disposing);
}
#endregion
[WebMethod]
public int Add(int a, int b)
{
return a + b;
}
}
}

Subject: RE: Java Client accessing a .NET Web Service
I don't know where the urban ledgend that .NET can't handle arrays of
complex types that contain complex types comes from, but its not true. I
have a service that returns arrays of complex types containing arrays of
complex types and it works fine with a .NET client.
Cheers
