i have an objectA that hold a lazy collection of other objectsB.
there may be serveral hundred objectsB's hence they are set to lazy load.

basically i am storing objectA in the HttpSession and when i come to use objectA i can no longer get the collection of objectB's as the Hibernate Session is closed.

is there a way to somehow overrided the lazy load option at run time?

or do i have to rework this?

You can do objectA.getObjectBs().size(); while the hibernate session is open.
This will load the collection into the objectA.
