RE: tapernate question
Yeah, I know about the new getCurrentSession() stuff. It's just a matter of me finding the time to sit down and write the stuff that I want. As I said, it shouldn't be that hard really.

RE: tapernate question
The main reason that I use the Spring stuff is for the transaction demarcation stuff. Hibernate doesn't include anything "out-of-the-box" that allows you to do "nested" transactions (i.e. REQUIRES_NEW). You'd have to roll that yourself and Spring has already done that for me.

RE: tapernate question
H. Well, that's the way Spring wraps it by default. I don't have time to look into it right now, but maybe you can check the Spring docs to see what to do in your situation. The Spring library is pretty thorough, so I would imagine that there's something you can do.

RE: tapernate question
Thanks, James. I am able to get the exception now. However, the exceptions seem to be wrapped into spring's DataAccessException. The original cause of HibernateException is gone. I tried to traverse the Exception track by getCause(), but only get the DataIntegrityViolationException and java.sql.BatchUpdateException. I am writing an application that has two fields that can violate the same contraints. The lost of HibernateException won't allow me to figure out the which field is duplicated.

RE: tapernate question
If you want more fine-grained control over what's going on, turn off transaction-per-request and use service methods with transaction interceptors on them to achieve what you want. The reason that you didn't get the exception is that the transaction isn't committing until the end of the request and that's when you'll get the unique constraint violation exception. The exception presenter might not even catch this, come to think of it. I actually changed the way Tapernate is implemented in my local copy.
