JAX-WS Example RPC Style

Creating JAX-WS example is a easy task because it requires no extra configuration settings.

JAX-WS API is inbuilt in JDK, so you don't need to load any extra jar file for it. Let's see a simple example of JAX-WS example in RPC style.

There are created 4 files for hello world JAX-WS example:

HelloWorld.java
HelloWorldImpl.java
Publisher.java
HelloWorldClient.java

The first 3 files are created for server side and 1 application for client side.

JAX-WS Server Code

File: HelloWorld.java

package com.javatpoint;
import javax.jws.WebMethod;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.jws.soap.SOAPBinding.Style;
//Service Endpoint Interface
@WebService
@SOAPBinding(style = Style.RPC)
public interface HelloWorld{
 	@WebMethod String getHelloWorldAsString(String name);
}

File: HelloWorldImpl.java

package com.javatpoint;
import javax.jws.WebService;
//Service Implementation
@WebService(endpointInterface = "com.javatpoint.HelloWorld")
public class HelloWorldImpl implements HelloWorld{
	@Override
	public String getHelloWorldAsString(String name) {
		return "Hello World JAX-WS " + name;
	}
}

File: Publisher.java

package com.javatpoint;
import javax.xml.ws.Endpoint;
//Endpoint publisher
public class HelloWorldPublisher{
	public static void main(String[] args) {
	   Endpoint.publish("http://localhost:7779/ws/hello", new HelloWorldImpl());
        }
}

How to view generated WSDL

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

JAX-WS Client Code

File: HelloWorldClient.java

package com.javatpoint;
import java.net.URL;
import javax.xml.namespace.QName;
import javax.xml.ws.Service;
public class HelloWorldClient{
 	public static void main(String[] args) throws Exception {
 	URL url = new URL("http://localhost:7779/ws/hello?wsdl");
 
        //1st argument service URI, refer to wsdl document above
	//2nd argument is service name, refer to wsdl document above
        QName qname = new QName("http://javatpoint.com/", "HelloWorldImplService");
        Service service = Service.create(url, qname);
        HelloWorld hello = service.getPort(HelloWorld.class);
        System.out.println(hello.getHelloWorldAsString("javatpoint rpc"));
     }
 }

Output:

Hello World JAX-WS javatpoint rpc
