SMPC and explicit transactions

monkeyden Sep 18, 2007 11:19 AM

I have seen many threads on the topic but none seem to solve this issue the "right way". I am currently using SMPC for the bulk of my application. I also have a background process which retrieves a Map from application scope and persists/merges the objects inside of it. This is in a completely separate thread. To do the saving, I need to be able to use transactions explicitly. Naturally, the transaction is not available because there is no Seam context. Has anyone an example of this?

Thanks.

For posterity sake....

In my EJB I just injected the SessionContext and the EM:
@Resource SessionContext ejbContext; @In private EntityManager em;

And had the EM join the transaction:
UserTransaction txn = ejbContext.getUserTransaction( ); txn.begin(); em.joinTransaction(); //do something txn.commit();
