In the ODMG standard, there is the concept of the "current transaction" of a given thread, i.e., there is an association between the threads and transactions. For the sake of ODMG, it is advisable to have one thread per one transaction and, conversely, one transactiob per thread. (I am talking about concepts, I have not experiences about what OJB does). For the PersistenceBroker API, there is a similar association, but I do not know exactly what happens if several thread share one txn or vice versa. So I would give the same advice.
