 Post subject: Does rollback undo in-memory changes after an Exception?

Hi,
With regards to exception handling:

I make a few in-memory changes in an entity. Then, I do a save() for the first time and it errors out, for some reason. Now, if I roll back the transaction, I believe that Hibernate will try to undo the changes in the database. Since this is the first time I am doing a save() there has been no change in the database. Will Hibernate undo the in-memory changes as well using the getter/setter? Or Should I need to undo the in-memory changes?

Thank you very much.
Madhan.

If an exception is thrown or rollback then you should throw away the session object or clear the cache. This addresses the in memory state.

By clear cache, do you mean "refresh()" so that the state of the object can be re-read?
Thanks,
Madhan.

No, it does not. However, I consider adding an option for this in a future version of Hibernate.

No I mean session.clear().
