Hi,

I'm having some problems with session cache and i'm asking for your help.

I have 2 threads each one with it's own session (i call it Session A and B), and they are acessing to a database.

They both load the same object from the database, and Session A changes that record and stores it back in the database. Than both Threads load that object again.

Thread A loads the object with the changes, and Thread B loads the original object. This happens because they are loading the object from their Session Cache instead of loading them from the database.

How can I refresh Session Caches when the database data changes?

Thanks,
Joao Rangel

It is not usually correct to use such long-lived sessions.

However, there are various ways:

Session.clear(), Session.refresh(), Session.evict(), etc...
