JAX-WS RPC

JAX-WS RPC Style example

JAX- WS RPC style web services use method name and parameters to generate XML structure.

1. Create a Web Service Endpoint Interface

JAXWSRPC.java

package com.devyan;

import javax.jws.WebMethod;

import javax.jws.WebService;

import javax.jws.soap.SOAPBinding;

import javax.jws.soap.SOAPBinding.Style;

@WebService

@SOAPBinding(style=Style.RPC)

public interface JAXWSRPC {

       @WebMethod

       String getHellowWorldAsString(String name);

}

2. Create a Web Service Endpoint Implementation

JAXWSRPCImpl.java

package com.devyan;

import javax.jws.WebService;

@WebService(endpointInterface="com.devyan.JAXWSRPC")

public class JAXWSRPCImpl implements JAXWSRPC{

       @Override

       public String getHellowWorldAsString(String name)

       {

             return "Hello JAXWS RPC"+name;

       }

}

3. Create a Endpoint Publisher.

Publisher.java

package com.devyan;

import javax.xml.ws.Endpoint;

public class Publisher {

       public static void main(String[] args) {

             // TODO Auto-generated method stub

             Endpoint.publish("http://localhost:7779/ws/hello", new JAXWSRPCImpl());

       }

}

After running the publisher code, you can see the generated WSDL file by visiting the URL:

4.Web Service Client

Create a web service client to access your published service.

JAXWSRPCClient.java

package com.devyan;

import java.net.MalformedURLException;

import java.net.URL;

import javax.xml.namespace.QName;

import javax.xml.ws.Service;

public class JAXWSRPCClient {

      

       public static void main(String[] args) throws Exception {

             URL url=new URL("http://localhost:7779/ws/hello?wsdl");

            

             QName qname=new QName("http://devyan.com/","JAXWSRPCImplService");

             Service service=Service.create(url, qname);

             JAXWSRPC jax=service.getPort(JAXWSRPC.class);

             System.out.println(jax.getHellowWorldAsString("Happy Leaning"));

                          

       }

}

OUTPUT:

Hello JAXWS RPCHappy Leaning
