Question

I am using Hibernate 3 version for my Application .

While going through tutorials on Hibernate, I found out that, SessionFactory should be created only once for the application.
So for this I have decided to use a static block inside a class and a static method to return this as shown.

public class SessionFactoryInitiliaztion {
    static {
        try {
            sessionFactory = new Configuration().configure().buildSessionFactory();
        } catch (Exception x) {
            x.printStackTrace();
        }
    }

    public static SessionFactory getSessionFactory() {
        return sessionFactory;
    }
}

Where exactly do I need to close this sessionFactory object , so that it resales the memory ?

I cannot think of any reason (offhand) why you would want to close the session factory while your application exists, so I wouldn’t be too concerned about reclaiming the memory. I would just close it when your application is shutting down.
