Running Jersey on Grizzly on Linux and Windows

I come from the background of Windows.NET, but I am trying to expand my experience and therefore took several Java projects. I'm currently trying to create a REST API, so I decided to go through Jersey here: http://jersey.java.net/nonav/documentation/latest/getting-started.html

I got a Hello World project for working on Windows (using NetBeans and Maven), however, when I try to do the same in Ubuntu (again using NetBeans and Maven), I get the following error:

Starting grizzly... Aug 09, 2012 11:27:46 AM com.sun.jersey.api.core.PackagesResourceConfig init INFO: Scanning for root resource and provider classes in the packages: com.javarest.javarest2 Aug 09, 2012 11:27:47 AM com.sun.jersey.api.core.ScanningResourceConfig logClasses INFO: Root resource classes found: class com.javarest.javarest2.HelloWorldResource Aug 09, 2012 11:27:47 AM com.sun.jersey.api.core.ScanningResourceConfig init INFO: No provider classes found.

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

HelloWorldResource.java:

 /* * To change this template, choose Tools | Templates * and open the template in the editor. */ package com.javarest.javarest2; import javax.ws.rs.*; /** * * @author ryan */ // 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"; } }

Main.java

 import com.sun.jersey.api.container.grizzly2.GrizzlyServerFactory; import com.sun.jersey.api.core.DefaultResourceConfig; import com.sun.jersey.api.core.PackagesResourceConfig; import com.sun.jersey.api.core.ResourceConfig; import org.glassfish.grizzly.http.server.HttpServer; import javax.ws.rs.core.UriBuilder; import java.io.IOException; import java.net.URI; import java.util.HashMap; import java.util.Map; import java.util.Map.Entry; public class Main { 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(); } }

So now I have a Mac, and I decided to try the same procedure. Not to my surprise, I ran into the same problem as in the linux environment. I had an employee who tried the same procedure on his machine, but it worked great for him. The only thing I noticed differently when I did this was the following popup: REST Popup

I always just clicked normally. Since my employee never received a pop-up, I tried it again, this time by clicking Cancel. This seems to be a trick.

I do not use Maven. To date (July 26, 2013) I include the following banks for working with a stand-alone grizzly server from my eclipse (Project | Run - no web.xml, etc.)

  • Grizzly wireframe 2.3.4.jar
  • Grizzly client-2.3.4.jar
  • Grizzly HTTP Server 2.3.4.jar
  • jersey-container-grizzly2-http-2.0.jar

To upload files: go to http://grizzly.java.net/dependencies.html and find non-maven developer 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; } }

You need to use the maven transformer to ensure that the service files are merged correctly. See Grizzly and Jersey Standalone Flask
