App Engine + JSP + Jersey Viewable Example

I’m putting together a simple App Engine webapp that’s using Jersey as the controller and JSP for the view. Wrapping a Jersey Viewable in a Response, provides a clean way to do this, but I had a bit of trouble getting everything wired up properly. After a little googling I found a post over at Don Park’s Daily Habit that helped me get things right. Here’s a full working example for anyone who’s trying to do the same thing:

Required JARs

I’m using Jersey 1.11

  • asm-3.1.jar
  • jersey-core-1.11.jar
  • jersey-server-1.11.jar
  • jersey-servlet-1.11.jar

JAX-RS Application

package example;
import java.util.HashSet;
import java.util.Set;
import javax.ws.rs.core.Application;
public class JaxRsApplication extends Application {
	public Set&gt; getClasses() {
		Set&gt; classes = new HashSet&gt;();
		return classes;

Root Resource

package example;
import java.util.HashMap;
import java.util.Map;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.core.Response;
import com.sun.jersey.api.view.Viewable;
public class HomeResource {
	public Response get() {
		Map model = new HashMap();
		model.put("word", "World");
		return Response.ok(new Viewable("/home", model)).build();
