Jakarta Commons are easily reusable components that can quickly be put to good use in any server-side Java development undertaking. In fact, components are not big applications, but sleek code bits that perform specific tasks very well. This book provides much-needed documentation and usage information about the popular sub-projects forming Jakarta Commonsso that you can efficiently incorporate them into Java applications.

Jakarta Commons have potential to extend the core functionality of the Java language (the Lang sub-project), and they can provide a Validation framework (Validator) and a database connection pool (Pool). Jakarta Commons can even manipulate XML and JavaBeans in a more intuitive and pragmatic fashion.

"From Lang to Net, BeanUtils to Collections, this book provides a real way in to the breadth and depth of Jakarta Commons. The many examples and step-by-step guides should help everyone get the best from these libraries."
--Stephen Colebourne, committer at Jakarta Commons and creator of Joda open-source libraries

"This book is by far the best resource available on Jakarta Commons and covers the subject matter clearly."
--James McGovern, coauthor of the best-selling book A Practical Guide to Enterprise Architecture
