Running Jersey on Grizzly on Linux and Windows

Question!

I come from a Windows .NET background, but am trying to expand my expertise, and so have picked up a few Java projects. Currently, I'm trying to create a REST API, and so I decided to go through the walk through for Jersey here: http://jersey.java.net/nonav/documentation/latest/getting-started.html

I've gotten the Hello World project to work fine in Windows (using NetBeans and Maven), however when I try to do the same exact thing in Ubuntu (again using NetBeans and Maven) I get the following error:

I've looked at this posting: Grizzly and Jersey standalone jar, and modified my pom.xml to have the build section that he had, but am still getting the same error. The code that I have is pretty much taken right out of the example, but I'll post it here:

HelloWorldResource.java:

/*

package com.javarest.javarest2;

import javax.ws.rs.*;

/**

// The Java class will be hosted at the URI path "/helloworld"
@Path("/helloworld")
public class HelloWorldResource {

    // The Java method will process HTTP GET requests
    @GET
    // The Java method will produce content identified by the MIME Media
    // type "text/plain"
    @Produces("text/plain")
    public String getClichedMessage() {
        // Return some cliched textual content
        return "Hello World";
    }
}

    private static URI getBaseURI() {
        return UriBuilder.fromUri("http://localhost/").port(9998).build();
    }
    public static final URI BASE_URI = getBaseURI();

    protected static HttpServer startServer() throws IOException {
        System.out.println("Starting grizzly...");
        //ResourceConfig rc = new PackagesResourceConfig("com.sun.jersey.samples.helloworld.resources");
        ResourceConfig rc = new PackagesResourceConfig("com.javarest.javarest2");
        return GrizzlyServerFactory.createHttpServer(BASE_URI, rc);
    }

    public static void main(String[] args) throws IOException {
        HttpServer httpServer = startServer();
        System.out.println(String.format("Jersey app started with WADL available at "
                + "%sapplication.wadl\nTry out %shelloworld\nHit enter to stop it...",
                BASE_URI, BASE_URI));
        System.in.read();
        httpServer.stop();
    }
}

I am not using Maven. As of Today (26 July, 2013) I include the following jars to work with standalone grizzly server from my eclipse (Project | Run - no web.xml etc.)

  • grizzly-framework-2.3.4.jar
  • grizzly-http-2.3.4.jar
  • grizzly-http-server-2.3.4.jar
  • jersey-container-grizzly2-http-2.0.jar

To download the files : head over to http://grizzly.java.net/dependencies.html and look for non maven developers files. The console server looks like

package test;

import java.io.IOException;
import java.net.URI;
import org.glassfish.jersey.grizzly2.httpserver.GrizzlyHttpServerFactory;
import org.glassfish.jersey.jackson.JacksonFeature;
import org.glassfish.jersey.server.ResourceConfig;
import org.glassfish.grizzly.http.server.HttpServer;


public class GrizzlyServer {

    private static final URI BASE_URI = URI.create("http://localhost:9090/service/");

    @SuppressWarnings("deprecation")
    public static void main(String[] args) throws IOException {


            final HttpServer server = GrizzlyHttpServerFactory.createHttpServer(BASE_URI, createApp());
            System.out.println(String.format("Application started.%nHit enter to stop it..."));
            System.in.read();
            server.stop();
    }

    public static ResourceConfig createApp() {
        ResourceConfig rc = new ResourceConfig()
        .packages("test")
        .register(JacksonFeature.class);

        return rc;

    }

}

Ok, so I now own a mac and figured I would try the same procedure there. Not to my surprise, I ran into the same problem that I did in the linux environment. I had a co-worker try the same procedure on his machine, but it worked fine for him. The only thing that I noticed different when I did it was I got the following popup: REST Popup

I had always just clicked ok. Since my co-worker never got the popup, I tried it again, this time clicking cancel. That seems to have done the trick.



You need to use a maven transformer to ensure that the service files are merged properly. See Grizzly and Jersey standalone jar
