Spring/Hibernate: Keep session open for thread, or open a new one? java, collection, following, continue, together

amy

Hi,

I am using Spring 3 together with Hibernate. I have a user request that starts a java thread in the spring controller and then a response is sent, so the thread might continue to work while the user from response has already been sent.

If I am working with lazy collections in my thread I get the following error:Code:
org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: my.model.MyClass.lazyCollection, no session or session was closed
I read I could use Hibernate.initialize(entity) to fully fetch the lazy collections but I cannot use this as I am filling the collection just in the thread. Furthermore I tried to use merge() but that still does not solve the problem.

Is there a way to manually keep the session open or to open a new one for the thread?

Thanks for your help!

Hello

I read I could use Hibernate.initialize(entity) to fully fetch the lazy collections

You should use that (initialize)

but I cannot use this as I am filling the collection just in the thread.

Can you post your DAO method?

I already solved the problem by autowiring the session factory, opening a session on my own and closing it on the end of the thread.

Thanks for your help, anyway!
