I'm want to use the hibernate in action examples in a swing application. In the book's example, the thread local patten has been used in a web application. So, the servlets requests was in a unique thread.
Can I use the session in ThreadLocal in a swing application? I don't konw if all objetcts will be in the same thread.

Is there some best pratice to controll the sessions in a swing application?

I suggest trying session-per-business transaction pattern and wrapping your business logic objects into Hibernate and transaction wrappers with using
HiveMind based Interceptor from HiveTranse ( http://hivetranse.sourceforge.net/ )
Spring based proxy (not HibernateTemplate) http://www.onjava.com/pub/a/onjava/2005 ... tions.html

Or roll your own CGLib based weaver: http://kgionline.com/articles/aop_1/aop1.jsp

Oh, and do not use lazy=true, make life simpler
