Validation framework was introduced by David Winterfeldt as an external plugin to Struts framework.
Since we are using Servlet 3, we don’t need to configure it in and we just need to annotate it with @Web Listener annotation.
The Request Dispatcher interface provides the facility of dispatching the request to another resource it may be html, servlet or jsp.
App Context is the servlet context listener implementation that will initialize the Database connection when application context is initialized and it also configures the log4j using it’s configuration xml file. We have provided a lot of tutorials on servlets in java, this tutorial is aimed to use all of those information to create a full-fledged web application with database connectivity and log4j integration for logging. DBConnection Manager; @Web Listener public class App Context Listener implements Servlet Context Listener App Error is our application exception handler servlet configured in deployment descriptor, it provides useful information to the user incase of 404 errors or application level exceptions and provide them hyperlink to go to login page of application. I strongly recommend to check out following tutorials if you are not familiar with any of these. package com.journaldev.servlet.errorhandler; import This post collects all my notes and references on j Query Form validation library.This includes a large bunch of sample code and a complete reference guide to all the built-in validation rules in the library.
