Hibernate Transaction
java code:
Transaction ts=session.beginTransaction();
Criteria criteria=session.createCriteria(Item.class);
criteria.add(Restrictions.idEq(product.getItem().getId()));
criteria.setLockMode(LockMode.PESSIMISTIC_WRITE);
Item item=(Item)criteria.list().get(0);
...
ts.commit();
...
Transaction tc=session.beginTransaction();
...
tc.commit();
Then I got the Exception:
Transaction not successfully started.

This is a pure Hibernate question that shouldn't have been posted in the
Tapestry users mailing list. Please stay on topic.

Are sessions thread safe? No.

Thx, I use HibernateSessionSource.create(). Is this thread safe?

Any of these options:
1) If you use managed transactions (i.e. @CommitAfter) don't commit yourself
2) If you really want to use the same session, start a new transaction
after committing. But it's a very questionable practice
3) Use HibernateSessionSource.create() to manage transactions manually
in a separate session
