It's not very process intensive if you are using 
a connection pool where it just hands you an 
already-open connection.  Hibernate can use a 
few different connection pools including JCS,
C3P0, OSCache, etc.

Subject: OT: Hibernate Session to User Session


I was reading in the Hibernate forums that when you have a WebApp > DAO
> Hibernate > DB design, and you open/close each Hibernate session at
every single DAO method call (what I do now) its actually quite
expensive, and is suggested that you attempt to maintain a Hibernate
Session in conjunction with a user Session to increase performance.

I had a question for anyone that has done this (without using
SpringFramework). My gut-reaction to this was to add a
HttpSessionListener to my webapp that created and stored a Hibernate
session in the user's session, and then close it when the Session
expired... will this not work? Anyone else have a good solution for
this?

TIA,
Riyad
