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. @WebMethod exposes the annotated method to web service clients.
package helloservice.endpoint;
import javax.jws.WebService;
@WebService
public class Hello {
private String message = new String("Hello, ");
public void Hello() {}
@WebMethod
public String sayHello(String name) {
return message + name + ".";
}}
