Cannot run MsgResource in Java Up and Running book

[Himai Minh]

Hi,
I used NetBean platform to create a Java Web Application project. I have msg.resources package that has MsgResources.java on p.182 of Java Web Service Up and Running book.
I have JerseyPublisher.java as well, which is outside the msg.resources package.
In the Libraries , I imported all the jar files : asm-3.1.jar , grizzly-servlet-webserver-1.8.3.jar, jersey-core-0.9-ea.jar, jersey-server-0.9-ea.jar and jsr311-api-0.9.jar as
mentioned in the book.

I opened my browser and type http://localhost:9876/
But it returns me "Internal Error".

Please help.
Thanks.

I found an example at http://theopentutorials.com/examples/java-ee/jax-rs/create-a-simple-restful-web-service-using-jersey-jax-rs/

import java.io.IOException;
import com.sun.jersey.api.container.httpserver.HttpServerFactory;
import com.sun.net.httpserver.HttpServer;
 
public class MsgResourceStartUp {
 
    static final String BASE_URI = "http://localhost:9875/";
 
    public static void main(String[] args) {
        try {
            HttpServer server = HttpServerFactory.create(BASE_URI);
            server.start();
            
            System.in.read();
            server.stop(0);
        } catch (IllegalArgumentException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

This can be the JerseyPublisher for the MsgResource example in the book.
