[OJB-developers] Some PersistenceBrokerImpl questions

[Daniel Fernn. E. <dfe...@wn...>]

Hi Thomas.

I have some questions about PersistenceBrokerImpl, as you know I'm working on JTA support for OJB, I have started with the PersistenceBroker interface, and then if everything goes fine will take a look at the ODMG interface.

I'm basically working with four methods, they are abortTransaction(), beginTransaction(), commitTransaction() and checkPoint(). Last two seems to be very similar, could you clarify me what checkPoint() is used for and why it should commit a transaction?

thanks in advance.
