When creating new Java web applications within an IDE such as Eclipse or NetBeans, the IDE creates a directory structure and uses its own internal builder to create WAR and EAR files. While these build tools may be convenient when starting to develop J2EE applications, when working on production grade projects, it’s important to create your own directory structure and build scripts to automate the building and deployment process. This tutorial will take you through automating the build process of a web application using Apache Ant as well as giving you a better understanding of exactly how web applications are laid-out and built within the EAR file.

Many view Checked Exceptions as a design flaw. In this article, I attempt to show how this flaw can be overcome using a base exception class to encapsulate exception handling.
