Tomcat.

Make sure you've the listener in the web.xml

 

            <listener>

 
<listener-class>com.htg.base.listener.TurbineContextListener</listener-class
>

            </listener>.

import javax.servlet.ServletContext;

import javax.servlet.ServletContextEvent;

import javax.servlet.ServletContextListener;

 

import org.apache.torque.Torque;

import org.apache.fulcrum.*;

import org.apache.stratum.configuration.*;
