JSF Deploy Exception: Invalid Dependencies for EntityManager Type

I just completed a billiards tutorial ( http://www.jboss.org/jdf/examples/ticket-monster/tutorial/Introduction/ ) and added a relaxation class to my solution.

package projectFoo.rest;
import java.util.List;
import javax.enterprise.context.RequestScoped;
import javax.inject.Inject;
import javax.persistence.EntityManager;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

import projectFoo.model.party;


@Path("/partys")
@RequestScoped
public class partyService {

@Inject
private EntityManager em;

@GET
@Produces(MediaType.APPLICATION_JSON)
 public List<party> getAllEvents() {
    @SuppressWarnings("unchecked")
    final List<party> results =
            em.createQuery(
            "select e from party e order by e.name").getResultList();
    return results;
}
}

@Inject emphasized, returns: "No bean has the right to inject at the injection point [JSR-299 §5.2.1]"

When I try to deploy the package, the process will fail and return the following message:

Unsatisfied dependencies for type [EntityManager] with qualifiers [@Default] at injection point.

Do I need to add a bean for Entity Manager? What should it look like? The manual does not mention this. In fact, I could not find any definition of beans in the final draft of the ticket monster.

EntityManager , CDI ( JPA- beans.xml).

class Resources {
   @SuppressWarnings("unused")
   @Produces
   @PersistenceContext
   private EntityManager em;
