The Java EE 6 Tutorial

Coding the Service Endpoint Implementation Class

In this example, the implementation class, Hello, is annotated as a web service endpoint using the @WebService annotation. Hello declares a single method named sayHello, annotated with the @WebMethod annotation, which exposes the annotated method to web service clients. The sayHello method returns a greeting to the client, using the name passed to it to compose the greeting. The implementation class also must define a default, public, no-argument constructor.

package helloservice.endpoint;

import javax.jws.WebService;
import javax.jws.webMethod;

public class Hello {
    private String message = new String("Hello, ");

    public void Hello() {

    public String sayHello(String name) {
        return message + name + ".";
