[jboss-user] [JCA/JBoss] - Completely confused JCA and Hibernate

My apologies. I've searched and searched. I'm confused about my current configuration for Hibernate.
Basically we use Hibernate.getCurrentSession() to 'get' and 'save' information. We have CMT and an XA-datasource configured.
Is Hibernate using any part of JCA for its work? (the example mysql-ds.xml was in the examples\jca directory). And if I want to use the WorkManager, what am I supposed to do? Is there some default RA to use with JBoss that already works with the WorkManager?
Here is the use case:
1) stateless EJB inserts a record into table A: (get the primary key from the insert)
2) asynchronously do some 'work' that will use the PK from step 1 to insert into child table B
The problem is
1) TX1 is created for the insert
2) TX2 is created by the WorkManager for the inserts into the child table B. But TX2 cannot see the changes made by TX1.
I can set the isolation level to read uncommited but that is ridiculous. I think TX1 and TX2 should be able to see the changes and act as a coordinated transaction.
It's just that this is trivial stuff and I can't imagine I need to write some RA just to do something this simple.
