There are three APIs that allow you do make your resource transactional
aware and get it running in the context of a global transaction:
org.omg.CosTransactions.Resource (JTS/OTS),
javax.transactions.xa.XAResource (JTA), and
javax.transaction.Synchronization (no two-phase commit).
The only thing you need is a way to tell the transaction manager to
place this resource inside the transaction, and there is no API to get
that done. I expect the connector architecture to provide something like
that, or at least define some way to configure it.
