An open source tool from the Jakarta Project, Ant is used to put together all the pieces of an application. As Ant has grown in popularity, developers have expanded its use and functionality. Ant: The Definitive Guide, 2nd Edition, is a totally re-worked, revised and expanded look at this extraordinary tool. This edition now covers everything from downloading, installing and configuring Ant to using Ant with JUnit to test code, running Ant in the popular Eclipse IDE (integrated development environment), and scheduling builds in Unix and Windows. Developers also learn how to use Ant with JavaServer Pages (JSP) to build web applications, with Enterprise JavaBeans (EJB) to build enterprise applications, and how to use Ant with XML.
