JSTL(Jsp Standard Tag Library) Kick Start（1）

The JSP Standard Tag Library is a collection of commonly used functions and tools invaluable to JSP developers to avoid re-creating the same functions on site after site.

jstl是jsp开发者开发网站中避免重复开发相同功能很有用的工具。

Sun has indicated that JSP development should be based around using tag libraries going forward, and will release JSP STL, as their official library.

Sun公司已经指出jsp开发要沿着使用标签库的方向发展，它将发布JspStl作为他们官方库。

This book starts with an in-depth discussion of the JSP STL, then goes beyond the standard library to teach developers to create their own tags to further encapsulate the most common features of their specific applications.

本书最初先深入讨论Jstl，然后跨过标准库教开发者创建他们进一步封装依据他们特定应用通用特性的标签。

Along the way, readers will also learn to use tags to access data, process XML, handle expressions, and further customize pages for international visitors.

这样，读者将同时学到使用标签访问数据，处理xml，控制表达式和为国际用户一步定制页面。

Later chapters explain how readers can expand the Standard Tab Library by creating their own tags.

后面的章节解释读者如何创建自己的标签来扩展jstl。
