I have a very long conversation (session per application). Another process can change any part of my underlying database. How do I completely clear my cache so all objects are looked up again?

use session.clear()

thanks alot. I'm now getting this though :

org.hibernate.HibernateException: reassociated object has dirty collection reference

Tom.

you should look up the objects again yourself manually.

Is there no way around this?

My application includes a replication process to a remote server. This is outside of hibernate and I don't really what has been updated.

My application is a swing app and it has lots of screens that can be switched without reloading.

So when my replication process runs I have to somehow mark all data objects in my application as 'dead' and reload them?
