I'm using hibernate 2.1 in the context of JTA transactions. I've enabled optimistic locking by timestamp. If I use the following jag of code to save, then I get stale object exceptions on subsequent saves in later transactions.
Code:
session = factory.openSession();
tx = session.beginTransaction();
session.save(order);
session.flush();
tx.commit();
session.close();
However, when I evict and reload subsequent saves occur without error.
Code:
session = factory.openSession();
tx = session.beginTransaction();
session.save(order);
session.flush();
session.evict(order);
order = (Order) session.load(order.getClass(), new Long(order.getWebOrderId()));
tx.commit();
session.close();
I hardly think that the evict and reload should be required. The timestamps seem to be getting set in both the entities and the database. Anyone have any ideas what I may be doing wrong?
