AJAX (Asynchronous JavaScript with XML) enables a dynamic, asynchronous Web experience without the need for page refreshes. In this tutorial, you will learn to build AJAX-based Web applications -- complete with real time validation and without page refreshes -- by following the construction of a sample book order application.

In this tutorial

• Introduction to AJAX
• Application design
• Implementing the application
• Running and testing the application

Objectives

• Learn to develop and design Web applications based on Asynchronous JavaScript with XML, or AJAX.
• Build a sample Web-based book order application which provides real time validation and page refresh, making user interaction efficient and smooth.

Prerequisites

The sample AJAX application in this tutorial runs on Tomcat. Tomcat is the servlet container that is used in the official reference implementation for the Java Servlet and JavaServer Pages technologies.

• Download jakarta-tomcat-5.0.28.exe from the Jakarta Site and run it to install Tomcat to any location you'd like -- c:\tomcat5.0, for instance.
• Download the source code and Web application wa-ajax-Library.war for this tutorial.
