What if we acquired a UoW with client session in JTS env?

Question

Dear all,
According to the application developer guide, session 7.5.2.5 - Using a Unit of Work When No External Transaction Exists,
======
When getActiveUnitOfWork returns a null Unit of Work, there is no existing external transaction. You must start a new external transaction.
Do this either by starting an external transaction explicitly using the UserTransaction interface, or by acquiring a new Unit of Work using the acquireUnitOfWork method on the server session.
======
What if the application acquire the UoW with client session instead?
Thanks and regards,
William

Answer 1

William,
Acquiring the UnitOfWork from a client session or Server session will accomplish the same thing.
One thing I would caution you on is that if your application is using JTA then I typically avoid having TopLink ever start the transaction. In this scenario the transactions should always be started by a container managed method on an EJB or through a UserTransaction. TopLink starting a JTA transaction would be an atypical usage.
