PersistenceBrokerAware and current transaction

["V.B. Skrypnyk" <va...@skrypnyk.net>]

Hi,

I am trying to implement my own cascading deletes of sorts through
PersistenceBrokerAware beforeDelete callback. Strangely (?) I can't seem to
get the current transaction by calling:

OJB.getInstance().currentTransaction()

so that I can add the affected dependent objects to it (so it may be saved).
I get the following exception:

 [java] org.odmg.DatabaseClosedException: Database is NULL, must have a DB
in order to create a transaction

Is this correct behaviour? It's the same thread, shouldn't I be able to
retrieve the current transaction?

Cheers,
--Bill.

Thank you, Armin.

I am using TxManagerFactory.instance().getCurrentTransaction() now.

OJB isn't a singleton, thus when calling
OJB.getInstance()
you will get a new Implementation instance.
