Hi,
I have a private thread running inside an application scoped component that
wakes up every 5 secs and does some housekeeping work. It needs access to an
EntityManager.
The @In is unreliable the em is always null. So I tried this:
| EntityManagerFactory emf =
Persistence.createEntityManagerFactory("viewDatabase");
| EntityManager em = emf.createEntityManager();
|
but when I tried to use it nothing happened, I figured it wasn't being flushed
automatically as I know seam does a lot for you but when I manually tried to
flush() it I got complaints about not being in a transaction.
I then tried to get a transaction from em.getTransaction() but then I got:
| java.lang.IllegalStateException: JTA EntityManager cannot access a
transactions
|
Makes sense from the reading of done on EJB just now, so then I thought I'll
try getting from JNDI as the reading I've done says the persistence context
will be associated with a transaction.
How does one do this? Is this indeed the right thinking (or indeed the right
forum for this or shall I post it in the EJB forum or JBoss forum?) Please
advise.
Thanks
Troy
