hi,
what do i use:
hibernate 3.0.5
jboss 4.0.3SP1
java 5.0
os: linux 64 Bit
mappingfiles,
i can send them by email, but they are ok. I working with them for a while in a SWT Application. Right now we transport the Apllication to ECHO (Web Framework based on Servlets)
my code:
Context context = Bellerophon.getApp().getContext();
UserTransaction transaction = (UserTransaction) context.lookup("java:comp/UserTransaction");
transaction.begin();
SessionFactory sessionFactory = (SessionFactory) context .lookup("java:/hibernate/SessionFactory");
Session session = sessionFactory.getCurrentSession();
//give my model the session
model.setQuery(session.createCriteria(Bin.class));
transaction.commit();
now we render the view and I get:
<stacktrace>
could not initialize proxy - the owning Session was clo
sed
so why does a session commit close my session? And if I don't do this and do a
Session session = sessionFactory.getCurrentSession(); In my model I get a: 2 OPen Session Error.
please help me...
