Prerequisites:

  1. JDK 1.6
  2. Eclipse IDE

Steps for creating JAX-WS webservice endpoint.

1) Open Eclipse IDE
2) Create java project named "JAXWSServer"


3)Create new package named "org.arpit.javapostsforlearning.webservice"

 4)Create JAXWSService Endpoint Interface.
HelloWorld.java
package org.arpit.javapostsforlearning.webservice;
import javax.jws.WebMethod;
import javax.jws.WebService;

@WebService
public interface HelloWorld {

 @WebMethod public String helloWorld(String name);
}
5)Create JAXWSService Endpoint implementation class.
HelloWorldImpl.java
package org.arpit.javapostsforlearning.webservice;
import javax.jws.WebService;

@WebService(endpointInterface="org.arpit.javapostsforlearning.webservice.HelloWorld")
public class HelloWorldImpl implements HelloWorld{

 public String helloWorld(String name) {
  return "Hello world from "+name;
 }

}
6) Create Endpoint publisher.
HelloWorldWSPublisher.java
package org.arpit.javapostsforlearning.webservice;
import javax.xml.ws.Endpoint;

public class HelloWorldWSPublisher {
 public static void main(String[] args) {
  Endpoint.publish("http://localhost:8080/WS/HelloWorld",new HelloWorldImpl());
 }
}
Run above program.Your webservice is published.You can check your service wsdl at http://localhost:8080/WS/HelloWorld?wsdl

Steps for creating JAXWS Client


1)Open eclipse and create a new java project JAXWSClient.
3) Now we need to generate the client stubs.So open your command line, and enter the wsimport command:
cd %project_home%/src
wsimport -s . http://localhost:8080/WS/HelloWorld?wsdl
you will find java classes generated and compiled under src->org->arpit->javapostsforlearning->webservice

4) Lets create client class now.
create JAXWSClient.java under src->org.arpit.javapostsforlearning.webservice.client
package org.arpit.javapostsforlearning.webservice.client;
import org.arpit.javapostsforlearning.webservice.HelloWorld;
import org.arpit.javapostsforlearning.webservice.HelloWorldImplService;

public class JAXWSClient {

    /**
     * @author Arpit Mandliya
     */
    public static void main(String[] args) {
        
        HelloWorldImplService helloWorldService = new HelloWorldImplService();
        HelloWorld helloWorld = helloWorldService.getHelloWorldImplPort();
        System.out.println(helloWorld.helloWorld("Arpit"));
    }
}

5) Run above program and you will get following output.
Hello world from Arpit

Congratulation,you have successfully created web service endpoint and client.Now in next post,we will deploy it on Tomcat.
