How do I get the JAX-RS @Path of a different resource during a POST?

Question

I have two REST classes for a simple web service (Jersey and GlassFish) that involves user resources - one to operate on all users (e.g., a factory for @POSTing) and another on

With the strict REST concept you can make it as one root resource

@POST   /users        -> CREATE a single user
@GET    /users        -> READ all users
@PUT    /users        -> UPDATE (REPLACE) all users @@?
@DELETE /users        -> DELETE all users @@?

@POST   /users/{id}   -> CREATE a single user's some other child; @@?
@GET    /users/{id}   -> READ a single user
@PUT    /users/{id}   -> UPDATE a single user
@DELETE /users/{id}   -> DELETE a single user

@Path("/users")
@Stateless
public class UsersResouce {

    // /users
    @POST
    @Consumes({MediaType.APPLICATION-XML, MediaType.APPLICATION-JSON})
    public Response createUser(final User user) {
        // persist the user here
        return Response.created("/" + user.getId()).build();
    }

    // /users
    @GET
    @Produces({MediaType.APPLICATION-XML, MediaType.APPLICATION-JSON})
    public Response readUsers() {
        //return all users
    }

    // /users/{id}
    @GET
    @Path("/{user_id: \\d+}")
    @Produces({MediaType.APPLICATION-XML, MediaType.APPLICATION-JSON})
    public Response readUser(
        @PathParam("user_id") final Long userId) {

        final User persisted = userBean.find(userId);

        if (persisted == null) {
            return Response.status(Status.NOT_FOUND).build();
        }

        return Response.ok().entity(persisted).build();
    }

    // /users/{id}
    @Consumes({MediaType.APPLICATION-XML, MediaType.APPLICATION-JSON})
    @PUT
    @Path("/{user_id: \\d+}")
    public Response updateUser(
        @PathParam("user_id") final Long userId,
        final User mergeable) {

        final User persisted = userBean.find(userId);

        if (persisted == null) {
            userBean.persist(mergeable);
        } else {
            persist.setName(mergeable.getName());
            userBean.merge(persisted);
        }

        return Response.status(Status.NO_CONTENT).build();
    }

    // /users/{id}
    @DELETE
    @Path("/{user_id: \\d+}")
    public Response deleteUser(
        @PathParam("user_id") final Long userId) {

        userBean.delete(userId);

        return Response.status(Status.NO_CONTENT).build();
    }

    @EJB
    private UserBean userBean;
}
