Mailer Tag Library

Of course, the JSTL only provides a set of standard tag libraries.

JavaServer Pages (JSP) tag libraries define declarative, modular functionality that can be reused by any JSP page. Tag libraries reduce the necessity to embed large amounts of Java code in JSP pages by moving the functionality of the tags into tag implementation classes.

The most common used tag library outside of the JSTL libraries is one for sending email.
