Jersey 2.2.0 on Google App Engine. Error 404. jersey init. works locally though - google-app-engine

Question

I am deploying my app using jersey 2.2.0 jars onto google app engine. I have been developing and running locally and it works well during local run/test.
I deployed to the google app engine, and I start getting Error: 404 erros for all resources. Checking google logs, at the first request it spits out the following
org.glassfish.jersey.server.ApplicationHandler initialize: Initiating Jersey application, version Jersey: 2.7 2014-03-12 18:11:31...
The jersey servlet spits out the following
I 09:27:38.889 org.glassfish.jersey.filter.LoggingFilter log: 1 * Server has received a request on thread Request EE25C261
GET http://xxxx.appspot.com/service/users/test

and then spits out the resource not found
I 09:41:15.094 org.glassfish.jersey.filter.LoggingFilter log: 3 * Server responded with a response on thread Request 9826AB68
< 404
It also adds one more line which suggests
I 09:27:39.180 This request caused a new process to be started for your application, and thus caused your application code to be loaded for the first time. This request may thus take longer and use more CPU than a typical request for your application.
Now, all this works on my local testing but is only an issue when deployed to Google App Engine.
Here's my web.xml
<?xml version="1.0" encoding="utf-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</web-app>
and my jersey class is

import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import com.poole.web.jpa.EMFService;
import com.poole.web.jpa.Users;

#Path("/users/")
public class UsersResource {
private static final Logger log = Logger.getLogger(UsersResource.class.getName());
#GET
#Produces("application/json")
#Path("test")
public String info() {
log.info("comes into test");
return "Hello Jersey on Google App Engine";
}
}
Any help will be appreciated. I am stuck in this frustrating problem of just plumbing it all together in GAE
