Tag Libraries Tutorial

Declaring Tag Libraries

You declare that a JSP page will use tags defined in a tag library by including a taglib directive in the page before any custom tag is used:

<%@ taglib uri="/tlt" prefix="tlt" %>

The uri attribute refers to a URI that uniquely identifies the tag library. This URI can be relative or absolute. If it is relative it must be mapped to an absolute location in the taglib element of a Web application deployment descriptor, the configuration file associated with Web applications developed according to the Java Servlet and JavaServer Pages specifications. The prefix attribute defines the prefix that distinguishes tags provided by a given tag library from those provided by other tag libraries.
