Nope, they are not supported. It's probably possible to support them if we want
it. So feel free to add a feature request to JIRA if you want me to spend some
time thinking about it.

I have just ran into the exact same problem,
I am starting up and want to read the database
to start communicating with registered end-points,
but cannot figure out how to do it.

If you are using EJB3 persistence try @PersistenceContext - it should be
available.

Yes, I have just got the following working:
- I had to make a Stateful bean, a POJO
didi not seem to work.
package com.mydomain;
import javax.ejb.Remove;
import javax.ejb.Stateful;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import
When looking up the EntityManager by hand from the JNDI I get:
| javax.persistence.TransactionRequiredException: no transaction is in
progress
|

Well, you do need a transaction running to use one you create manually. :(

So basically there is no Transaction during startup? So I cannot expect
@PersistenceContext nor a manual lookup to work?
Is there any way to start a Transaction by hand?

There is never a transaction unless someone somewhere starts one. There's no
reason that anyone would have created a transaction around object creation at
startup.
You can look up the UserTransaction from JNDI and start it a transaction just
as you would in any component where you are
I'm not sure if we can support conversational components at startup. Gavin
will have to chime in.
In the meantime, you could always look get an emfactory and create one
yourself.
