Jersey Maven configuration

I am trying to setup a Jersey RESTful service, the problem is that I am getting the following error when trying to do GET request to the following API: http://localhost:8080/GroupAppServer/api/status:

com.sun.jersey.api.container.ContainerException: The ResourceConfig instance does not contain any root resource classes.

Here is my web.xml file:

<?xml version="1.0" encoding="UTF-8"?>

    xmlns="http://java.sun.com/xml/ns/javaee"

        <servlet-name>jersey-servlet</servlet-name>
        <url-pattern>/api/*</url-pattern>
    </servlet-mapping>
</web-app>

under src I have a package called "com.groupappserver.api" which holds my Status class. Here is the code:

package com.groupappserver.api;

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

import com.groupservice.utils.Response;

@Path("/status")
public class Status
{
    @GET
    @Produces(MediaType.APPLICATION_JSON)
    public Response getStatus() 
    {
        return new Response();
    }

}

Here is my pom.xml:

Any ideas why I am getting this error? and how can I fix this?
