Apache Jakarta Commons: Reusable Java Components (Bruce Perens' Open Source) (Paperback)

The Apache Jakarta Commons project is a collection of freely-reusable, opensource Java components. Commons components are used in a wide variety ofprojects, including Apache Tomcat, Hibernate, and many other commercialand open source projects.This book is a Java developer's guide to the Apache Jakarta Commons project.It covers in detail the twelve most important Commons packages, with sampleprogram code provided for each. Included are a number of remarkably usefulideas for working the various Commons packages, such as using HttpClient toaccess web resources, File Upload for handling HTTP file upload, BeanUtilsfor easy form generation, implementations of various protocols such as FTPand NNTP, and building a command line tool to search for the location ofclasses on the class path.Also included are detailed instructions for combining the Commons projectlibraries with the popular Eclipse IDE. Plus, the book includes a handy 75-page Jakarta Commons quick reference Appendix.

• Easy-to-follow coverage of twelve indispensable Jakarta Commons packages

• Code examples that show innovative uses of Commons components, including using HttpClient to access Web resources, FileUpload for handling HTTP file uploads, and BeanUtils for easy form generation

Save time and money with reusable open source Java™ components

Master the Jakarta Commons Library of Open Source JavaTM Components

Using the Apache Jakarta Commons reusable Java™ components, you can leverage the work of the global open-source community to solve common programming problems reliably, quickly, and inexpensively. But, to use the Commons libraries effectively, you need far more guidance than the official documentation offers. In Apache Jakarta Commons: Reusable Java™ Components, Will Iverson covers what Java developers need to know to take full advantage of Jakarta Commons—starting right now.

Iverson begins with a definitive overview of the Commons project: goals, installation, and getting started with Commons components. Next, he presents example-rich chapters on the twelve most useful Commons packages, covering topics ranging from HTTP FileUpload to database connectivity. Iverson provides detailed code samples for every component he describes. After you've mastered the core Jakarta Commons packages, you'll constantly rely on this book's handy seventy-five page quick-reference. Iverson's coverage includes

• Downloading Commons project libraries and installing them into Eclipse

• Programmatically accessing resources via HTTP, FTP, NNTP, and other Internet protocols

• Using the Jakarta Commons suite of configurable object pools

• Managing database connectivity in Swing applications—and anywhere containers aren't doing it for you

• Using BeanUtils to generate forms and gain runtime access to information provided by JavaBeans-style objects

• Traversing complex object graphs with JXPath

• Using Jakarta Commons' advanced collections tools to establish richer object relationships

• Extending java.lang with better methods for manipulating core classes

• Implementing conversion routines, configurable logging, command-line help, and more

• Exploring the newest packages, including emerging "sandbox" packages

Whether you're building code for front-end Web applications, client-side software, or back-end servers, learning Jakarta Commons will make you far more efficient. Apache Jakarta Commons is the fastest way to master and get results with Commons.
