package org.apache.struts.webapp.example;

import javax.servlet.ServletContext;

import javax.servlet.ServletContextListener;

import org.apache.torque.Torque;



public final class  TorqueLoader implements ServletContextListener {
	private ServletContext context = null;

    public void contextInitialized(ServletContextEvent event) {
    	context = event.getServletContext();
       
        try { 
		 String torqueConfig = context.getRealPath("/WEB-INF/torque.properties"); 
		 Torque.init(torqueConfig); 
		 torqueLoaded = true; 
        } catch (Exception ex)
        {
        	context.log("Couldn't init torque engine: " + ex.getMessage());  	
        	
        }
		 
    }
      
    public void contextDestroyed(ServletContextEvent event) {
