ne emf.createEntityManager(EXTENDED) any more?

Hi!

I am using ejb3-rc8 on JBoss-4.0.4.GA.

I am trying to get an EXTENDED EntityManager inside a servlet. Doing this in a lervlet just seemed to be the simplest way to write some data to the DB while migrating to a new, rewritten version of our application.
I look up the EntityManagerFactory and UserTransaction from JNDI, call em.join(utx) and would be happy if I did not need an EntityManager in EXTENDED PersistenceContext.

The docs I found all mention using

EntityManagerFactory.createEntityManager(PersistenceContextType.EXTENDED)

but that method does not seem to be there. I can only find

createEntityManager();
createEntityManager(Map properties);

How do I go about getting this job done?
If injection into servlets worked, I just would do

@PersistenceContext(type=EXTENDED)
EntityManager em;

in my Servlet, but since it doesn't, there has to be another way.

Thanks for any hints you can offer.

Regards,
Phil

EMF always returns an extended EM now.

Hmm... why then do I get "detached object passed to persist" when I try to persist a newly created entity with collection mapping?

I can persist anything just fine, but when I create an entity that holds a List of other entities (even when the list is still empty), that fails.
I have already tried to merge() the entit instead of persisting it, but then em.find will return null for it while still in the same transaction. I would expect to see and use the entity later on to fill that collection...

I am confused,
