Learn JAX WS in Few Seconds..

Implementing web service Endpoint/Client with JAX WS

Developing Web Service End Point

1) In Eclipse  create a java project "JAXWS-Server".

2) Create JAXWS-Service Endpoint Interface:

--------------------------------------------------------------------------

package mysimple.example.define;

import javax.jws.WebMethod;

import javax.jws.WebService;

@WebService

public interface Greeting {

@WebMethod String sayHello(String name);

}

-------------------------------------------------------------------------- 

3) Create JAXWS-Service Endpoint Implementation class:

-------------------------------------------------------------------------- 

package mysimple.example.define;

import javax.jws.WebService;

@WebService(endpointInterface = "mysimple.example.define.Greeting")

public class GreetingImpl implements Greeting  {

@Override

public String sayHello(String name) {

return "Hello, This is simplest JAX-WS example By :: " + name;

}

}

--------------------------------------------------------------------------  

4) Create Endpoint Publisher class:

-------------------------------------------------------------------------- 

package mysimple.example.publish;

import javax.xml.ws.Endpoint;

import mysimple.example.define.GreetingImpl;

public class WSPublisher {

public static void main(String[] args) {

Endpoint.publish("http://localhost:8080/WS/Greeting",new GreetingImpl());

}

}

-------------------------------------------------------------------------- 

5) Run the WSPublisher….and your WebService is published.

Check the service wsdl http://localhost:8080/WS/Greeting?wsdl

Developing Web Service Client :

1) In eclipse create a new java project JAXWS-Client

2) we need to generate the client stubs by following command(on the src path)

Command : wsimport -keep -verbose http://localhost:8080/WS/Greeting?wsdl

1. Remove all the class files
2. Create the  Client Class which will be dependent on the stubs

-------------------------------------------------------------------------- 

package mysimpleexample.client;

import mysimple.example.define.Greeting;

import mysimple.example.define.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("Manish_Kumar_Jaiswal"));

System.out.println("------->>  Call Ended");

}

}

-------------------------------------------------------------------------- 

3. Output :

------->>  Call Started

Hello, This is simplest JAX-WS example By :: Manish_Kumar_Jaiswal

------->>  Call Ended
