I have a similar problem; for one I also wanted to inject a stateless bean into a servelt, but since that doesn't seem to work. So next I tried injecting the same bean in a "normal" app, but I get the same problem :(

App-Code:

  | public class SimpleTest
  | {
  | 
  | 	@EJB
  | 	private static ICustomerDispatcher disp;
  | 
  | 	public static void main(String[] args)
  | 	{
  | 		injectionMode();
  | 	}
  | 
  | 	private static void injectionMode()
  | 	{
  | 		System.out.println("injectionmode!");
  | 
  | 		if (disp != null)
  | 		{
  | 			Customer newCust = disp.createCustomer("Jane", "Smith");
  | 
  | 			System.out.println(newCust.getLastName());
  | 			System.out.println(newCust.getId());
  | 		}
  | 		else System.out.println("no dispatcher!!");
  | 	}
  | 

Bean:

  | @Stateless
  | @Local(ICustomerDispatcher.class)
  | @Remote(ICustomerDispatcher.class)
  | public class CustomerDispatcherBean implements ICustomerDispatcher
  | {
  | 	@PersistenceContext
  | 	EntityManager em;
  | 
  | 	public static final String RemoteJNDIName = CustomerDispatcherBean.class.getSimpleName() + "/remote";
  | 	public static final String LocalJNDIName = CustomerDispatcherBean.class.getSimpleName() + "/local";
  | 	
  | 	public Customer createCustomer(String firstName, String lastName)
  | 	{
  | 		Customer newCust = new Customer();
  | 		newCust.setFirstName(firstName);
  | 		newCust.setLastName(lastName);
  | 		em.persist(newCust);
  | 		return newCust;
  | 	}
  | 
  | 	public Customer findCustomer(int id)
  | 	{
  | 		return em.find(Customer.class, id);
  | 	}
  | }
  | 

And the interface:

  | @Local
  | @Remote
  | public interface ICustomerDispatcher
  | {
  | 	public Customer createCustomer(String firstName, String lastName);
  | 	public Customer findCustomer(int id);
  | }
  | 

Well, I skipped the Customer entity ... since it's a POJO with an @Entity annotation.
