I'm a newbie to spring and hibernate and am in the learning process. I was wondering what would be causing spring to reload. I have been taking a look at this post

http://forum.hibernate.org/viewtopic...ighlight=leaks

and also at this one

http://acs.lbl.gov/~hoschek/javatree...1/doc/114.html

I know that this has to do with the SessionFactory being recreated everytime on DB Access. I am wondering if this is a configruation files that is causing this

or if I am going to have to make changes to the code.

import org.hibernate.Session;
import org.hibernate.SessionFactory;

abstract public class AbstractDAO {
    private SessionFactory sessionFactory;

    public void setSessionFactory(SessionFactory sessionFactory) {
		this.sessionFactory = sessionFactory;
	}

	protected Session getCurrentSession() {
    	return sessionFactory.getCurrentSession();
    }

	public AbstractDAO() {
	}
}

How do you load the application context?

[smu1997]

I just noticed that the Application Context is be created each time the Object is used. Thanks for the advice. Once I created a singleton for the Appplication context my problem went away.
