Git is the version control system developed by Linus Torvalds for Linux kernel development. It took the open source world by storm since its inception in 2005, and is used by small development shops and giants like Google, Red Hat, and IBM, and of course many open source projects.

This book is for all open source developers: you are bound to encounter it somewhere in the course of your working life. Proprietary software developers will appreciate Git’s enormous scalability, since it is used for the Linux project, which comprises thousands of developers and testers.

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.

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.

Chapters include:

• Overview
• FileUpload
• HttpClient
• Net
• Pool
• DBCP (Database Connection Pool)
• BeanUtils
• JXPath
• Logging
• Lang
• Collections
• Codec
• CLI (Command-Line Interface)
• Other Projects
