FIX: WSDL Tool Cannot Generate Web Service Proxies in Visual J# .NET (815258)

WORKAROUND

To work around this problem in Microsoft Visual Studio .NET 2002, you can generate the proxy for JScript .NET, and then manually change the proxy file to make the classes compile by using the Visual J# .NET complier.

For the default HelloWorld Web service, you must make the following changes in the JScript .NET proxy to convert it to a JSharp .NET proxy:

1. Remove the following line in the class header:

   //@cc_on
   //@set @debug(off)

2. Change the Import statements. For example, replace

   import System;

   with the following code:

   import System.*;

3. Change the Attribute of class and methods. For example, replace

   /// <remarks/>
   public System.Diagnostics.DebuggerStepThroughAttribute() System.ComponentModel.DesignerCategoryAttribute("code") System.Web.Services.WebServiceBindingAttribute(Name="Service1Soap", Namespace="http://tempuri.org/") 

   with the following code:

   /** <remarks/> */
   /** @attribute 
   System.Diagnostics.DebuggerStepThroughAttribute()*/
   /** @attribute 
   System.ComponentModel.DesignerCategoryAttribute("code")*/
   /** @attribute 
   System.Web.Services.WebServiceBindingAttribute(Name="Service1Soap", Namespace="http://tempuri.org/")*/

4. Add the public keyword before the class name as follows.

   public class Service1

5. In the constructor setting, change the URL. For example, replace

   this.Url = "http://localhost/WebService/Service1.asmx";

   with the following code:

   this.set_Url("http://localhost/WebService/Service1.asmx");

6. Change the syntax of the method signature and the variable declaration to JSharp .NET style.

The following code describes a generated proxy in JScript .NET and the corresponding JSharp .NET version after manual changes:
