You could use servlet filters to have the hibernate session open until the
request is processed. There are articles in the www.hibernate.org that explains
different patterns to handle situations similar to yours... Hibernate session
needs to be open in order for the objects to load the collections or any lazy
properties... Also, if the object is dettached then you need to re-attach it to
the current session for it to be loaded or used... Hope this helps...

I´m using Struts 1.2.8 with Hibernate 3.0.5 and I´m doubt with some concept
designs for ORM with MVC:
A Hibernate session get's instantiated in my DAO constructor (Model). Later
on, the JSP (View) catches the Hibernate persisted objects populated in the
request or session by the Controller and shows the data.
Question is:
If I close Hibernate session in the Model, before the View, as by default
the objects are lazy-instantiated, that is, the data would be retrieved from DB
when it´s accessed, the JSP complains that session is closed.
Besides, closing the session after the View I would be breaking the MVC
pattern.
I'm trying to retrieve Blob objects not sucessfully, due the problem
above... the only way would be disable lazy-instantiation??
