JAX-WS Example RPC Style

Steps

1. First, make a Web Service Endpoint Interface with all the method declarations you wish to include in the Web Service.
2. Make a class for the Endpoint interface implementation.
3. At last, establish an endpoint publisher that installs the web service and creates and publishes the Endpoint at the given location.

Example

Let's make four files, three for the server and 1 for the client.

• HeyNinjas.java
• HeyNinajsImpl.java
• Publisher.java
• HeyNinjasClient.java

JAX-WS Server Code

• HeyNinjas.java

package com.codingninjas;  
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 HeyNinjas{  
    @WebMethod String getHeyNinjasAsString(String name);  
}

• HeyNinajsImpl.java

package com.codingninjas;  
import javax.jws.WebService;  
//Service Implementation  
@WebService(endpointInterface = "com.codingninjas.HeyNinjas")  
public class HeyNinjasImpl implements HeyNinjas{  
    @Override  
    public String getHeyNinjasAsString(String name) {  
        return "Hey Ninjas JAX-WS " + name;  
    }  
}

       Endpoint.publish("http://localhost:7779/ws/hey", new HeyNinjasImpl());

}

JAX-WS Client Code

• HeyNinjasClient.java

package com.codingninjas;  
import java.net.URL;  
import javax.XML.namespace.QName;  
import javax.XML.ws.Service;  
public class HeyNinjasClient{  
    public static void main(String[] args) throws Exception {  
    URL URL = new URL("http://localhost:7779/ws/hey?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://codingninjas.com/", "HeyNinjasImplService");  
        Service service = Service.create(URL, name);  
        HeyNinjas hello = service.getPort(HeyNinjas.class);  
        System.out.println(hello.getHeyNinjasAsString("Coding Ninjas rpc"));  
     }  
 }

Frequently Asked Questions

What is JAX-WS used for?

A technology for creating XML-based web services and clients is called JAX-WS.

What is SOAP on the web?

A messaging protocol called SOAP makes it possible for the scattered components of an application to communicate.

What is the use of JAXB API?

The XML document is presented to the program in a Java format by JAXB, which makes it easier for Java programs to read XML documents.

What does JAX-RS stand for?

Java API for RESTful Web Services is referred to as JAX-RS. JAX-RS is an API and specification for the JAVA-based computer language that supports RESTful Web Services.

What is the difference between Jersey and JAX-RS?

Jersey is a JAX-RS implementation, whereas JAX-RS is a standard (basically a definition).
