A JSTL primer, Part 1: The expression language
Simplify software maintenance for JSP applications by avoiding scripting elements
Summary: The JSP Standard Tag Library (JSTL) is a
collection of custom tag libraries that implement general-purpose
functionality common to Web applications, including iteration and
conditionalization, data management formatting, manipulation of XML, and
database access. In this first installment of his new series on
developerWorks, software engineer Mark Kolb shows you how to use JSTL
tags to avoid using scripting elements in your JSP pages. You'll also
learn how to simplify software maintenance by removing source code from
the presentation layer. Finally, you'll learn about JSTL's simplified
expression language, which allows dynamic attribute values to be
specified for JSTL actions without having to use a full-blown
programming language.
