How to specify LifeCycle Listener listener class in web.xml?

I want to get notified once the server got started successfully.. For that I have added the below in the web.xml

<listener>    <listener-class>com.server.container.Listeners</listener-class> </listener>

Listeners is class which implements org.apache.catalina.LifecycleListener.

Is this correct? As of now i am not getting any notification during server startup end. Do i need to do anything extra?

In J2EE, Listener notifies whenever some action (context created, destroyed, request or session attribute added, removed, etc..) happens on the server.

Please find the below sample listener code below:

ApplicationListener Class (in your project):-

package com.myproject;

import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;

public class ApplicationListener implements ServletContextListener {

    @Override
    public void contextInitialized(ServletContextEvent arg0) {
        System.out.println(" Server Starting !!!!!! ");

        //Any other code you can place here
    }

    @Override
    public void contextDestroyed(ServletContextEvent arg0) {
        System.out.println(" Server Shutting down !!!!!! ");
    }
}

web.xml changes: Add below code to your web.xml

<listener>
        <listener-class>
             com.myproject.ApplicationListener 
        </listener-class>
   </listener>

Also, please ensure that you have got "servlet-api.jar" file in your classpath.
