This tutorial is for people who want to run a JAX-WS example (Endpoint + Client) in just five minutes.

What you need to run this example:

  1. JDK 1.6
  2. Eclipse .
  3. Be Excited 😉

Note:- You can download the source code for this example from the resources section.

Developing WebService End Point

1) Open Eclipse, and create a java project “WS-Server”.

2) Create WS-Service Endpoint Interface:

package juma.mohammad;

import javax.jws.WebMethod;
import javax.jws.WebService;

@WebService
public interface Greeting {
	 @WebMethod String sayHello(String name);
}

3) Create WS-Service Endpoint Implementation class:

package juma.mohammad;

import javax.jws.WebService;

@WebService(endpointInterface = "juma.mohammad.Greeting")
public class GreetingImpl implements Greeting {

	@Override
	public String sayHello(String name) {
		return "Hello, Welcom to jax-ws " + name;
	}

}

4) Create Endpoint Publisher class:

package juma;

import javax.xml.ws.Endpoint;

import juma.mohammad.GreetingImpl;

public class WSPublisher {
	public static void main(String[] args) {
		Endpoint.publish("http://localhost:8080/WS/Greeting",new GreetingImpl());
	}
}

5) Run the WSPublisher…. Guess what .. your WebService is published..
Wow.. check your service wsdl http://localhost:8080/WS/Greeting?wsdl

Developing WebService Client :

1) Open eclipse and create a new java project WS-Client

2) As you know we need to generate the client stubs… but how?

open your command line, and enter the wsimport command:

CD %CLIENT_PROJECT_HOME%\src
wsimport –s . http://localhost:8080/WS/Greeting?wsdl

You will find 6 java classes generated, and compiled under src/juma/mohammad.

You can remove *.class files , no need for them 🙂

3) Now Lets create Client Class which will be dependent on the stubs:

package juma;

import juma.mohammad.Greeting;
import juma.mohammad.GreetingImplService;

public class Client {
	public static void main(String[] args){

GreetingImplService service = new GreetingImplService();
Greeting greeting = service.getGreetingImplPort();
System.out.println("------->>  Call Started");
System.out.println(greeting.sayHello("Ali"));
System.out.println("------->>  Call Ended");
	}
}

4) Run the Client Class…. the output should looks like:

------->>  Call Started
Hello, Welcom to jax-ws Ali
------->>  Call Ended

Congratulations…. you managed to develop jax-ws Endpoint , Client..

The next tutorial will be how to deploy your Web Service on Tomcat.
