Re: T5ï¼s getting new Hibernate session in a lengthy thread
Maybe you can directly use HibernateSessionSource service instead of HibernateSessionManager.
HibernateSessionSource.create() creates a new session always, and do remember to commit and close the session by yourself.
Thanks,

Hi,
Yes, I think so. HibernateSessionSource is top of HibernateSessionManager.

Hi,
HibernateSessionManagerImpl uses HibernateSessionSource to create a session,
if we use HibernateSessionSource service in code as suggested by you, then
seems ok, right?

Sorry, my fault. If code don't call any method of HibernateSessionManager, it won't create a session.

Re: T5ï¼s getting new Hibernate session in a lengthy thread
Posted by DH <ni...@gmail.com>.
I haven't tried it yet because now my application is out of tapestry-hibernate.
But from source code of tapestry-hibernate, it should be doable.
But I still doubt how you close the session created by HibernateSessionManager (thread scope).
If you don't close it manually, the session still last fro the whole request process.
If close manually, maybe 'session has closed' exception is thrown by tapestry-hibernate because at the end tapestry would try to close the session of HibernateSessionManager, but it has been closed manually.
Thanks,
DH
