Hi, i have a strange problem in my hibernate application. It is a web application but i don't think that this does matter according to my problem.

5. Error saving a object using getCurrentSession().save(obj)    forum.hibernate.org

I just implemented auto id using Hibernate using MySQL with no problems. Is the column name in the database for myObject really "MyObjectId"; that doesn't seem like a typical column name, you may want to double check that. The only times -- of which I am aware -- that mysql will automatically set a column is with an auto increment or ...

Hello, I am getting the exception "org.hibernate.SessionException: Session is closed!" intermittently in a production environment when trying to get the Transaction via: Session session = sessionFactory.getCurrentSession(); Transaction transaction = session.getTransaction(); So far I am unable to reproduce this error on a developer machine unless I specifically close out the session with session.close(), however I cannot find any instances of something like ...

7. sessionFactory.getCurrentSession() ?    forum.hibernate.org

Well, even though I am running on JBoss 3.2.5 (yeah, old), but I am accessing Hibernate from both MBeans and EJB. EJB works fine (well, sort of, reason later), but MBeans obviously don't run in the context of a JTA (is there a way to make them? I am new to MBeans). So, currently, I am resorting to the Session-in-ThreadLocal pattern ...

Hi, Apologies in advance what what may seem to be a silly question. I am working with Hibernate 3.0.5 and really appreciate the tool.

12. Question about getCurrentSession & JOTM in an unmanaged    forum.hibernate.org

Hello, I'm try to use getCurrentSession() with JOTM in an un-managed environment. getCurrentSession() throws an exception unless I explicitly begin a transaction before getCurrentSession() is called. (JTASessionContext) txn = transactionManager.getTransaction(); if ( txn == null ) { throw new HibernateException( "Unable to locate current JTA transaction" ); } I understand this is the intended behavior, as in a managed environment the ...

15. SessionFactory.getCurrentSession();    forum.hibernate.org

Hibernate version: 3.1.2 I'm migrating to hibernate 3 from hiberante 2. I still have a HibernateHelper class which manages the current sessions and transactions. This was needed in hibernate 2. Hibernate 3 can handle it's own current session. So what do I do? This: public Session getSession() { Session session = sessionFactory.getCurrentSession(); try { if (session == null) { Interceptor interceptor ...

16. SessionFactory.getCurrentSession()... does this create    forum.hibernate.org

It does create new session. However Hibernate session is very lightweight object, so I would suggest you not to worry about it. If you still do, then wrap your code into some lazily instantiated ThreadLocal and on exit check if it has been initialized at all and then call commit. If( thl.getSession() != null) { thl.getSession().getTransaction().commit(); }

18. Threading issue when using GetCurrentSession()    forum.hibernate.org

In my Hibernate 3.1 web application, I'm allowing the user to save to the database in one session while a background thread is reading data from the database in a different session. I'm using hibernate.current_session_context_class="thread" and GetCurrentSession() to manage my sessions, guaranteeing that each thread has its own session. In theory I thought that would work fine, but I'm encountering strange ...

Here's actually an interesting discussion on that very topic at JavaRanch: http://saloon.javaranch.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic&f=78&t=003806 The getCurrentSession() method looks at the current context to see if a session is stored in there. If there is one, it uses it, and if there isn't a session in the current context, it creates a new one and saves it in there. On the other hand, openSession ...

24. method getCurrentSession() from SessionFactory class    forum.hibernate.org

You can use this method to access an object that implements Hibernate's Session interface, which is the primary interface through which applications can use Hibernate. A session is a single-threaded context provided by Hibernate; your application will likely use it to issue queries; begin, commit, and roll back transactions; save and update objects; and the like. getCurrentSession() retrieves whatever session is ...

25. Calls to getCurrentSession() returns a closed session    forum.hibernate.org

I am using Hibernate 3.3.1GA. I'm using the OpenSessionInViewFilter, and I'm running in to problems specifically when multiple requests are executed in quick succession. What happens is calls to SessionFactory.getCurrentSession() will return a closed session. Why does this happen?? Why would get current session ever return a closed session.

I may not be the right person to answer this question, but i'll give you what I do know about the session factory. W hen you close the factory you are not disposing of the object itself.
