Re: Transactions

Hi Ricardo,

Yes, Cayenne provides transaction API with access to JDBC connections:

=
https://cayenne.apache.org/docs/5.0/cayenne-guide/persistent-objects-objec=
tcontext/#transactions

You can use one of CayenneRuntime "performInTransaction(..)" flavors to =
wrap both Cayenne and direct JDBC operations and access Transaction =
object and its connections via "BaseTransaction.getThreadTransaction()" =
while inside the tx.

Thanks,
Andrus
