Using JSTL

JSTL includes a wide variety of tags that naturally fit into discrete functional areas. Therefore, JSTL is exposed via multiple URIs to clearly show the functional areas it covers and give each area its own namespace. Table 6-1 summarizes these functional areas, subfunctions in each area, tags in each subfunction, and the prefixes used in the Duke's Bookstore application.

The URIs used to access the libraries are:

Core: http://java.sun.com/jstl/core

XML: http://java.sun.com/jstl/xml

Internationalization: http://java.sun.com/jstl/fmt

SQL: http://java.sun.com/jstl/sql

The JSTL tag libraries comes in two versions (see Twin Libraries). The URIs for the JSTL-EL library are as shown above. The URIs for the JSTL-RT library are named append _rt to the end.
