WebServices- JAX-WS Document Style

JAX-WS -Document Style

  1. SOAP Body can be structurted in any way you like

  2. Document style web services can be validated against predefined schema.

  3. In document style, SOAP message is sent as a single document.

  4. Document style message is loosely coupled.

  5. In Document style, SOAP message loses the operation name.

  6. In Document style, parameters are sent in XML format.

In JAX-WS development, convert from -RPC style” to -Document style” is very easy, just change the @SOAPBinding style option

Example

1. JAX-WS Web Service End Point files

*************************************************
1. Create a Web Service Endpoint Interface with
@SOAPBinding(style = Style.Document)  
*************************************************
package endpoint;

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 getHelloWorldMsg(String msg);  
}  


*************************************************
2. Create a Web Service Endpoint Implementation
*************************************************
package endpoint;

import javax.jws.WebService;  
//Service Implementation  
@WebService(endpointInterface = "endpoint.HelloWorld")  
public class HelloWorldImpl implements HelloWorld{
	@Override
	public String getHelloWorldMsg(String msg) {
 // TODO Auto-generated method stub
 return "Your Message from WebService is : "+msg;
	}     
}  


*************************************************
3. Create an Endpoint Publisher & Run as Java Application
*************************************************
package endpoint;

import javax.xml.ws.Endpoint;  
//Endpoint publisher  
public class HelloWorldPublisher{  
    public static void main(String[] args) {  
       Endpoint.publish("http://localhost:7771/ws/hellodoc", new HelloWorldImpl());  
       System.out.println("WSDL Published !!");
        }  
}

4.Test generated WSDL. Ex: http://localhost:7771/ws/hellodoc?wsdl

2. Web Service Client files

Create Java Web Service Client & Run as Java Application

package client;

import java.net.URL;  
import javax.xml.namespace.QName;  
import javax.xml.ws.Service;

import endpoint.HelloWorld;  
public class HelloWorldClient{  
    public static void main(String[] args) throws Exception {  
    URL url = new URL("http://localhost:7771/ws/hellodoc?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://endpoint/", "HelloWorldImplService");  
       Service service = Service.create(url, qname);  
       HelloWorld hello = service.getPort(HelloWorld.class);  
       System.out.println(hello.getHelloWorldMsg("Hello, from Client"));  
    }  
}
