       Body:
I too have seen a similar issue.  I think your problem is that there isn't a transaction started for Hibernate to registerSyncronization with.  At least I was able to resolve the issue by starting a transaction.

However, my confusion is that Hibernate does this only once per connection.  I start a transaction, do a session.load, then rollback the transaction.  Then, I do another load which works fine.  Hibernate seems to assume that once the a connection is open it has only one transaction associated with it.  That does not make intuitive sense to me.

    Summary: NullPointerException in SessionImpl.connect under jboss
       Type: Bug

     Status: Unassigned
   Priority: Minor

    Project: Hibernate2
   Versions:
             2.1 beta 3

Environment: win2k, jboss 3.2.1, sun vm 1.4.1-b21

Description:
Thanks for Hibernate, it's very nice.

I'm using the version labelled "2.1beta3b" from sourceforge.  I get a NullPointerException under jboss when I try to use a session where Hibernate got the connection from a DataSource.  Hibernate 2.0 works fine, and 2.1beta3b works fine in a standalone JVM.

My code is:

		Session s = hFactory.openSession();
		Query q = s.createQuery("from com.nlg.dps.teo.booking.db.ItineraryLineItem as ili where ili.booking=:id and ili.origin!=ili.destination");
		q.setProperties(key);
		List lineItems = q.list();      <-- crash site
