What you'll learn

This two-day module introduces the JSTL, or JSP Standard Tag Library, actually a set of four custom tag libraries that establish a portable standard for common processing tasks in JSP. JSTL is a major part of the new scriptless authoring style encouraged (and enabled) by the JSP 2.0 specification. This module covers all four JSTL libraries in depth: *The core actions, which support JSP expressions for JSP 1.x containers, flow control for procedural processing in JSPs, and resource access *The formatting and internationalization/localization actions, which standardize formatted numeric and date/time output as well as multi-language support *The SQL actions, which dramatically simplify access to relational data from a JSP *The XML actions, which give JSPs a simple, powerful framework by which to parse, address and transform XML data using XPath and XSLT Each individual tag in each library is covered, with precise syntactic rules shown in a standard format in the student guide, and JSTL techniques and best practices are discussed for each library. An extensive set of example applications illustrates common usage of each major group of actions, and the module culminates with a wrap-up workshop that brings core, SQL, and XML techniques to bear in a single application.

Prerequisites

Students should be well-versed in JSP page authoring. Knowledge of JSP 2.0 is a plus, but is not required; the module's primary audience is JSP 1.x authors.
