Hi guys,
I'm trying to inject Stateless EJB into my JAX-RS webservice via Annotations. Unfortunately the ejb is just null and I get a NullPointerException when I try to use it.

@Path("book")
public class BookResource {

    @EJB
    private BookEJB bookEJB;

    public BookResource() {
    }

    @GET
    @Produces("application/xml")
    @Path("/{bookId}")
    public Book getBookById(@PathParam("bookId") Integer id)
    {
        return bookEJB.findById(id);
    }
}

What am I wrong doing?
Here are some informations about my machine:

• Glassfish 3.1
• Netbeans 6.9 RC 2
• Java EE 6

Can you guys put some working example? And thank you for every advises and examples?
