Since the article focusses on the
Since the article focusses on the
XMLHttpRequest object and how it
fits into Ajax, the article requires you have a good understanding of Javascript,
XML, DHTML, and the HTML DOM. Invaluable tutorials on these technologies can be

System Configuration
In this article, we will build simple Java web applications utilizing Ajax. To run
the example applications, you will need
Java SDK 1.4.2
or later and J2EE 1.3 or later. In
addition, you will need a servlet container such as
Tomcat 5.0.
Ant scripts are included to facilitate compilation and deployment. You
will need Apache Ant to run the build
scripts. You may download Tomcat already bundled with the article's
examples (pre-compiled and deployed) in the download section at the end of this article.
