TransientObjectException. Help!

Hibernate 3.2CR3

I get a TransientObjectException when the following happens:

- Log in to site.
- Put User instance (entity object) in web session
- Many requests are handled, User instance works perfectly.
- Stop/Start web application
- Web session persists, any use of the User instance now generates this TransientObjectException error.

What is the best way to resolve? I'd prefer something that doesn't have to hit the database to verify the User instance on every single web request.

Code:

org.hibernate.TransientObjectException: org.project.User

Gamigin,
Don't know if this'll help, but i received the same exception with a similar (though not exact) stack trace. In my situation i was able to reorganize the Hibernate xml into a form that worked. I feel like my original setup s/h worked, but at least there was a work-around. For the details, see this post: http://forum.hibernate.org/viewtopic.php?t=965437&highlight=transientobjectexception+foreignkeys&sid=2435ca2afbeb7ae19a999c65cc86f5f4.
(If link doesn't work, search in this forum for TransientObjectException ForeignKeys.)
