JAX-WS web service eclipse

Prerequisites: JDK 1.6 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.vcampus.webservice" 4. Create JAXWSService Endpoint Interface. HelloWorld.java

package org.vcampus.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.vcampus.webservice;  
import javax.jws.WebService;  
  
@WebService(endpointInterface="org.vcampus.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.vc.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. 2. 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->vc->webservice 3. Lets create client class now. create JAXWSClient.java under src->org.vc.webservice.client

package org.vcampus.webservice.client;  
import org.vcampus.webservice.HelloWorld;  
import org.vcampus.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"));  
    }  
}

4. 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.
