| How about this:
|
|
| | @WebService()
| | public class MissionStatusService {
| |
| | @PersistenceContext
| | EntityManager em;
| |
| | public MissionStatusService() {
| | //do nothing
| |
| | }
| | .....
| | }
|
I did try that.
Then my web service handler that uses the em to create the response fails with
a null pointer error for em.
