Included in this distibution:

Documentation ('doc/web' directory)

• Getting Started: A quick roadmap to help you get started with this release.
• Release Notes: Release history of the Standard 1.0 taglib.
• JSTL 1.0 Specification developed by the JSR052 expert group under the Java Community Process.
  • The specification is a formal description of the functionality and features of the JSTL 1.0 tag set.
• Sun's JSTL web site lists several books about JSTL that are available or will be available shortly.

Examples ('examples' directory)

The standard-examples application included with this distribution demonstrates the current capabilities of JSTL, exploring idioms and usage patterns when appropriate.

Implementation of JSTL ('src' and 'conf' directories)

Every effort has been made to provide a functional, robust, and speedy implementation of JSTL. For developers, the code is commented thoroughly to help provide an understanding of design considerations and salient implementation details.

Classes in any of the subpackages of javax.servlet.jsp.jstl represent JSTL API classes. Classes under org.apache.* represent implementation classes. The implementation's package structure is organized as follows:

  org.apache.taglibs.standard
   .tag         tag handlers and routines related to them
      .common      handlers and support routines common for RT/EL attributes
          .core    core library (common)
          .fmt     i18n-capable formatting tags (common)
          .xml     XML manipulation library (common)
	  .sql	   SQL library (common)
      .el          handlers specific to expression language (EL) evaluation
          .core    core library (EL)
          .fmt     i18n-capable formatting tags (EL)
          .xml     XML manipulation library (EL)
	  .sql	   SQL library (EL)
      .rt          handlers specific to rtexprvalue (rt) evaluation
          .core    core library (rt)
          .fmt     i18n-capable formatting tags (rt)
          .xml     XML manipulation library (rt)
	  .sql	   SQL library (rt)
   .tei         TagExtraInfo classes (common to both libraries)
   .tlv         TagLibraryValidator classes (and associated helpers)
   .lang        expression-language support and implementation
      .support     ExpressionEvaluator, ExpressionEvaluatorManager
      .jstl        JSTL 1.0 expression language

The javax.servlet.jsp.jstl.* tree is discussed in the JSTL specification.

Enjoy!
