Hibernate version: 2.1.6

Mapping documents:

Code between sessionFactory.openSession() and session.close():

Full stack trace of any exception that occurs:

Name and version of the database you are using: mysql 1.4

Debug level Hibernate log excerpt:

I want to program a graphic display like memory monitor in Java 2D example to demostrate real-time changes. I want to refresh the diaplay in less than a minute, so It is a short period of time. But if I fetch the data from database frequently, There will be a large amount of memory usage and the program will be momory killer.

Any ideas? Thanks.

Regards,

Check out the docs. Pay particular attention to the Performance chapter.

Thanks, I will do it.
