transactionCommitted

public void transactionCommitted(DBTransaction transaction)

Description copied from interface: TransactionListener

called after a successful database commit; the transaction is already inactive. Note that you cannot start a new transaction within the call of this method, since subsequent listeners would not have a chance to react on this transaction end.

If you need to access/update resources of this database from this method, start a new thread that opens a new transaction.
