[jboss-user] [JBoss Portal] - Advice needed on using Hibernate with Portlets

I want to use a HibernateSession to store and retrieve my data. Question one: does opening and closing a Hibernate session 10 times introduce a drastic overhead compared to opening and closing it once? (In this scenario there can be a good few hundred concurrent users) If it does, how can I use one session for all portlets? Ex: HibernateSession gets opened(); [Portlet1: processAction()] Portlet2: doView() Portlet1: doView() Portlet3: doView() .... HibernateSession gets closed(); To put it another way: 1. How can I run code BEFORE any portlet (processAction or doView) method gets called? 2. How can I run code AFTER all (processAction and doView) methods have been called?
