1. Session & HttpSession, best practice pattern forum.hibernate.org

Hello, What would be best practice for the following pattern: The user logs in. The User object is retrieved and stored in the HttpSession. Thereafter, we use the HttpSession-cached object unless we make changes to the User object. I understand that the User record in the DB may change and the HttpSession object will not reflect the change. How this would ...

2. Session in View Pattern and Portlet Development forum.hibernate.org

I'm about to use Hibernate and Spring in a Portlet project. And would like to know how to apply the Session in View pattern.

7. Question about the Open Session in View pattern forum.hibernate.org

Come on, I can't be the only person to ever wonder about this. The behavior I'm seeing appears to directly violate the documentation. If I'm a complete moron and missed something obvious, then tell me. That's fine. I just want to know what's going on. In case it matters, I'm using MySQL 4.1.18 as the database.

8. Open Session in View pattern doubt - help forum.hibernate.org

I learned and believed filters complete running before the response is sent and before the page is rendered. Is the author talking about response of the earlier request? I mean closing the open session of request1 while sending the response for request2? I feel like I am missing something great here. Most of you guys seem to have already landed in ...
