How to access SessionFactory instance stored in SerlvetContextListener class

[mDennis10]

I want my hibernate SessionFactory instance to be loaded when my application is deployed so I created a class named HibernateContext.

package org.LMS.Model;

import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;


public class HibernateContext implements ServletContextListener{

	SessionFactory sessionFactory;
	@Override
	public void contextDestroyed(ServletContextEvent arg0) 
	{
		sessionFactory = new Configuration ().configure ().buildSessionFactory ();
	}

	@Override
	public void contextInitialized(ServletContextEvent arg0) 
	{
		sessionFactory.close();		
	}

}//end HibernateContext class

I configured my web.xml file to reflect this change.

 <!-- HibernateContext Listener Mapping -->
  <listener>
  	<listener-class>org.LMS.Model.HibernateContext</listener-class>
  </listener>

My problem is that how can is access the SessionFactory throughout my application from the HibernateContext class.Please tell me if there
is a better way of accomplishing this.

Ok I found a solution

package org.LMS.Model;

import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;


public class HibernateContext implements ServletContextListener{

	private static SessionFactory sessionFactory;
	@Override
	public void contextDestroyed(ServletContextEvent arg0) 
	{
		sessionFactory = new Configuration ().configure ().buildSessionFactory ();
	}

	@Override
	public void contextInitialized(ServletContextEvent arg0) 
	{
		sessionFactory.close();		
	}

	public static SessionFactory getInstance () 
	{
		return sessionFactory;
	}
}//end HibernateContext class

But now when I run the application i'm getting a 404 for all the jsp & servlets. How do I fix this

Just saw the problem. didn't even realize that I made such a silly mistake I had this:

  public void contextDestroyed(ServletContextEvent arg0) 
    {
        sessionFactory = new Configuration ().configure ().buildSessionFactory ();
    }
 
    @Override
    public void contextInitialized(ServletContextEvent arg0) 
    {
        sessionFactory.close();     
    }

So I was making a SessionFactory instance in my ContextDestroyed method and closing the resources in the contextInitalized method. What I should have done was:

	@Override
	public void contextDestroyed(ServletContextEvent arg0) 
	{
		sessionFactory.close();
	}

	@Override
	public void contextInitialized(ServletContextEvent arg0) 
	{
		sessionFactory = new Configuration ().configure ().buildSessionFactory ();
	}
