Consuming a .NET Web Service with Apache AXIS.


In this article, I will present an example on how to develop a typical HelloWorld Web Service with .NET on IIS, and how to consume that service with Apache AXIS in Java. Apache AXIS is SOAP implementation provided by Apache. AXIS SOAP implementation is available in two languages, C++ and Java. In this article, I will use the Java implementation of AXIS SOAP. Apache AXIS can be downloaded from here.

HelloWorld.asmx file is a simple text file in C#. The class HelloWorld just extends with the class WebService and implements a method SayHelloWorld(). To make this method a web method, it is given the attributed [WebMethod]. IIS simply takes care of generating the SOAP message and the WSDL file for the client.

Web Service on IIS in .asmx file

<%@ WebService Language="C#" Class="HelloWorld" %>
using System;
using System.Web.Services;
public class HelloWorld : WebService 
     [WebMethod] public String SayHelloWorld() 
          return "Hello World";

To consume this Web Service with AXIS, WSDL file for the HelloWorld Web Service needs to be downloaded.

Now, to consume this Web Service, Apache AXIS provides a tool WSDL2Java to convert WSDL specification file to Java code. This tool generates the four Java classes, and that will take care of processing XML and SOAP messaging, and makes the use of Web Service as simple as calling an object on a local machine.

> java org.apache.axis.wsdl.WSDL2Java <A href="http://localhost/HelloWorld.asmx?WSDL">http://localhost/HelloWorld.asmx?WSDL</A>

The above tool will generate the following four class files which can be used to access that Web Service.


This is how the client program looks like:

package org.tempuri;
public class Client
      public static void main(String [] args)
                  HelloWorldLocator loc = new HelloWorldLocator();
                  HelloWorldSoap port = loc.getHelloWorldSoap();
            catch(Exception e)

Before coming across Apache AXIS, my reaction to developing and consuming Web Service in Java was that it was a lot of pain. But with Apache AXIS, developing and consuming Web Service is as simple as in .NET platform.

.Net has a utility called wsdl.exe to generate C# proxy class from any Web Service WSDL file.
please use wsdl /? to find help information on how to generate the proxy classes.

More easire way is to use

Go to Project -- > Add Web Reference
type the Url of your web service and will create proxy classes for that web services.
This will work for a web service written in any language as long as it uses Web Services standards
and has a WSDL file. Smile | :)
