JavaServer Pages Standard Tag Library
The JavaServer Pages Standard Tag Library (JSTL) encapsulates core functionality common to many JSP applications. For example, instead of iterating over lists using a scriptlet or different iteration tags from numerous vendors, JSTL defines a standard tag that works the same everywhere. This standardization lets you learn a single tag and use it on multiple JSP containers. Also, when tags are standard, containers can optimize their implementation.
JSTL has support for common, structural tasks such as iteration and conditionals, tags for manipulating XML documents, internationalization tags, and tags for accessing databases using SQL. It also introduces the concept of an expression language to simplify page development. JSTL also provides a framework for integrating existing custom tags with JSTL tags.
The JSTL reference documention at
<
JWSDP_HOME>/docs/jstl/index.html
contains some introductory material. For a complete description of the JSTL tags, see the JSTL 1.0 Specification Public Review Draft. This chapter assumes that you are familiar with the material in the Using Tags section of Chapter 16.In This Chapter
