j2ee: JSTL [19/27]

The JavaServer Pages Standard Tag Library (JSTL) encapsulates, as simple tags, core functionality common to many JSP applications

JSTL is hosted at Jakarta - along with many other useful tag libraries

JSTL, unlike the other libraries, is standardized through the Java Community Process (JCP).

JSTL comes in two versions:

• 1.0 - for Servlets 2.3, JSP 1.2
• 1.1 - for Servlets 2.4, JSP 2.0

JSTL is the origin of the Expression Language that is now standard in JSP 2.0, so you can use the EL in any JSTL 1.0 tags in a JSP 1.2 container, but the EL is not available outside of JSTL tags (like in a JSP 2.0 container).

To deploy the JSTL, just follow the same directions as for any tag library.
