//Service Implementation
//@SchemaValidation
@WebService(endpointInterface = "org.techsavvy.HelloWorld")
public class HelloWorldImpl implements HelloWorld{

    @Override
    public String getHelloWorldAsString(String name, String company) {

        return "Hello!! your name is " + name+ " and you work in " +company+ ".";

}

//Endpoint publisher
public class HelloWorldPublisher{

    public static void main(String[] args) {
       Endpoint.publish("http://localhost:9999/ws/hello", new HelloWorldImpl());

    }
