Re: [J2] Persistence Usage?

[Scott T. Weaver]

Unfortunately they are not on all DBs.  In HSQL checkpoint and commit do 
the same thing.  However, with Oracle, you still need to commit even 
after a checkpoint or you loose everything.

All,
I have a simple question, it seems that we have 2 ways
of using the current persistence plugin:
Transaction tx =
registry.getPersistenceStore().getTransaction();
tx.begin();
registry.getPersistenceStore().lockForWrite(pa);
pa.addUserAttribute(userAttrName, userAttrDesc);
tx.commit();
or
persistenceStore.lockForWrite(internalUser);
persistenceStore.getTransaction().checkpoint();
I would like to clarify the difference between the two
approaches.  My understanding was that they were
equivalent.  Is this correct?
Regards,
David.
