We have such a layer working in my company. Unfortunately is is closed source :-( The basic idea is very simple: 1. have Transaction interface. providing methods like begin(), commit(), abort() lockRead(...), lockwrite(...), getObjectByQuery(Query), getCollectionByQuery(Query), etc. 2. write a OJB ODMG Implementation of this interface. 3. write a TransactionFactory that serves TransactionOjbImpls.
