Jakarta Commons是Jakarta的子项目,它创建和维护着许多独立软件包,这些包一般与其他框架或产品无关,其中收集了大量小型、实用的组件,大部分面向服务器端编程。 

  Commons的包分成两部分:Sandbox,Commons代码库。Sandbox是一个测试平台,用来检验各种设想、计划。本文介绍的组件属于Commons代码库,文章将展示各个组件的功能、适用场合,并通过简单的例子介绍其用法。

  可重用性是Jakarta Commons项目的灵魂所在。这些包在设计阶段就已经考虑了可重用性问题。其中一些包,例如Commons里面用来记录日志的Logging包,最初是 为其他项目设计的,例如Jakarta Struts项目,当人们发现这些包对于其他项目也非常有用,能够极大地帮助其他项目的开发,他们决定为这些包构造一个"公共"的存放位置,这就是 Jakarta Commons项目。

内容介绍:

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.
