Jersey 2.0 servlet dependencies

There are two dependencies that Jersey 2.0 has for adapting its application to a Servlet instance.

archetype-comment.xml

<!-- use the following artifactId if you don't need servlet 2.x compatibility -->

HelloResource.java

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;

@Path("hello")
public class HelloResource {

  @GET
  @Produces(MediaType.TEXT_PLAIN)
  public Response get() {
    return Response.ok("hello").build();
  }
}

ideal-comment.xml

<!-- use the following artifactId for servlet 3.x configuration features that don't require web.xml -->

jersey-container-servlet-core.xml

<!-- This supports Servlet 2.x -->
<dependency>
  <groupId>org.glassfish.jersey.containers</groupId>
  <artifactId>jersey-container-servlet-core</artifactId>
  <version>2.1</version>
</dependency>

jersey-container-servlet.xml

<!-- This does NOT support Servlet 2.x -->
<!-- (but it does support Servlet 3.0's web.xml-less configuration) -->
<dependency>
  <groupId>org.glassfish.jersey.containers</groupId>
  <artifactId>jersey-container-servlet</artifactId>
  <version>2.1</version>
</dependency>

JerseyApp.java

import javax.ws.rs.ApplicationPath;

import org.glassfish.jersey.server.ResourceConfig;

@ApplicationPath("myapp")
public class JerseyApp extends ResourceConfig {

  public JerseyApp() {
    register(HelloResource.class);
  }
}

Thank you, thank you, THANK YOU!

I spent 3hrs trying to get Servlet 3.x + Jersey 2.x to play nice together. Nothing but 404s, until I found your blog post (http://www.theotherian.com/2013/08/jersey-2.0-servlet-3.0-problems-applicationpath.html) on jersey-container-servlet-core vs jersey-container-servlet.
