Hey Joseph,
I was wondering. From where you got this code?
Context Listener are used to initialize like you can have Database
Connection there.
contextInitialized -> runs when you deploy your web application.
contextDestroyed -> runs when you undeploy.
I use this for hibernate connection.
package com.usaa.sas.model;
import javax.servlet.ServletContext;
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
import javax.servlet.annotation.WebListener;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
/**
* Application Lifecycle Listener implementation class HibernateUtill
*
*/
@WebListener
public class HibernateUtill implements ServletContextListener {
private SessionFactory sessionFactory=null;
/**
* Default constructor.
*/
public HibernateUtill() {
// TODO Auto-generated constructor stub
}
/**
* @see
ServletContextListener#contextInitialized(ServletContextEvent)
*/
public void contextInitialized(ServletContextEvent event) {
// TODO Auto-generated method stub
ServletContext sc = event.getServletContext();
try {
sessionFactory= new
Configuration().configure().buildSessionFactory();
sc.setAttribute("sessionFactory", sessionFactory);
}
catch(Throwable ex){
System.err.println("Intial Creation Failed"+ex);
}
}
/**
* @see
ServletContextListener#contextDestroyed(ServletContextEvent)
*/
public void contextDestroyed(ServletContextEvent event) {
// TODO Auto-generated method stub
sessionFactory.close();
}
}
