JAX-WS Example Document Style

Like RPC style, we can create JAX-WS example in document style. To do so, you need to change only one line in service interface.

You need to use Style.DOCUMENT for @SOAPBinding annotation in place of Style.RPC. Let's have a quick look at this:

File: HelloWorld.java

Now Let's see the full example of JAX-WS in document style.

There are created 4 files for hello world JAX-WS document style 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.DOCUMENT)
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());
        }
}

If you run the publisher class, it may generate following error:

Wrapper class com.javatpoint.GetHelloWorldAsString is not found. 
Have you run APT to generate them?

To solve the problem, go to bin directory of your current project in command prompt and run the following command:

wsgen -keep -cp . com.javatpoint.HelloWorldImpl

Now, it will generator 2 files:

SayHello
SayHelloResponse

Paste these files in com.javatpoint directory and then run the publisher class.

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 document"));
     }
 }

Output:

Hello World JAX-WS javatpoint document
