A Simple SOAP Web Service Example in Eclipse :-

Create Basic Web Service

1. Create new Dynamic Web Project.
2. Create new Java class (call it “DoesMagic”).
3. Add method like this (perhaps):

1	public class DoesMagic{

2	public String doBasicStuff(String message)

3

{

4	return "This is your message: " + message;

5

}

6

}

4. Right click on class you just made, New -> Other -> Web Services -> Web Service, you should get a form like the one below:

This will create all the necessary files to be able to publish your class as a web service.  If you want you can also create a client automatically by moving the slider – but what it generates may be hard to understand at first glance, so I have written a simple example of client code (see later on…).
5.  In order to run the web service – just,  Run as -> Run on Server.  Once the web service is running and alive on Tomcat – then we should be able to use it via some client code (see next bit).

Create Basic Web Service Client

Must create a project that has all the axis.jar type stuff in the WebContent folder – this can usually be made by generating a client application via the above wizard – you don’t have to use all the auto generated classes to access your web service, just do the following:
1.  Create a new Java Class – call it TestClient.
2.  Make it a main class, and enter the following code:

01	import javax.xml.namespace.QName;

02	import org.apache.axis.client.Call;

03	import org.apache.axis.client.Service;

04

05	public class TestClient {

06

07	public static void main(String [] args)

08

{

09

try{

10	String endpoint = "http://localhost:8080/TestWebService/services/DoesMagic";

11

12	Service service = new Service();

13	Call call = (Call) service.createCall();

14	call.setTargetEndpointAddress( new java.net.URL(endpoint) );

15	call.setOperationName( new QName("http://testPackage.fc.com", "doBasicStuff") );

16

17	String ret = (String) call.invoke( new Object[] {"Hello World"} );

18	System.out.println(ret);

19

}

20	catch(Exception e){

21	System.err.println(e.toString());

22

}

23

}

24

}

3.  Go to your web service project you made before and look at the source code for the wsdl file that has been created.  It’s in the folder WebContent -> wsdl.  Inside there you will find a wsdl that is the same name as your class.
4. You need to look at the wsdl and find the endpoint – which looks similar to:

"http://localhost:8080/TestWebService/services/DoesMagic"

and you need to get the namespace and the method name you want to invoke  (as shown above, should be in a very similar format).

5. In this case, when we get to the point that the call.invoke command is being issued it is casting the result to a String and we are sending in a String called “Hello World” – this should create a message in the console like “This is your message: Hello World”.

6. To test the class, just run the project as a Java Application and you should see the result in the Console printed out.
