Applied Software Engineering with Apache Jakarta Commons is a software engineering based guide to the Apache Jakarta Commons components (e.g., Betwixt, Digester, Discovery, Collections), other Apache projects such as Ant, the Axis Web Service toolkit, and the popular JUnit framework. The book emphasis focuses on solutions to complex problems using a simple task-driven approach. In this task-driven approach, the idea is to define a generic problem, for example Java class instantiation, and then provide solutions in multiple contexts, such as Collections-based factories, the Discovery package, or even the Launcher package. The book includes a companion CD-ROM with samples and source code.
