How and to whom should I introduce PersistenceContext when running tests through Jersey / Grizzly?

Question

I have this class (combination of JAX-RS / Jersey and JPA / Hibernate):

public class Factory {
  @PersistenceContext(unitName = "abc")
  EntityManager em;
  @Path("/{id}")
  @GET
  public String read(@PathParam("id") int i) {
    return em.find(Employee.class, i).getName();
  }
}

This is unit test:

public class FactoryTest extends JerseyTest {
  public FactoryTest() throws Exception {
    super("com.XXX");
  }
  @Test
  public void testReadingWorks() {
    String name = resource().path("/1").get(String.class);
    assert(name.length() > 0);
  }
}

Everything is fine here, except for one thing: it emis NULLinside read(). It seems that the grizzly bear (I use this server along with the Jersey test platform) does not introduce PersistenceContext. What am I doing wrong here?
