Supplied Library Tags (JSTL)
This tag library provides basic JSTL-like functionality for Info*Engine tasks. This includes the ability to set variables, iterate over lists and use conditional logic.
These tags are included in the /com/infoengine/tlds/iejstl.tld tag library. To use these tags, you must include a taglib directive in your task similar to the following:
<%@ taglib uri="/com/infoengine/tlds/iejstl.tld"
prefix="c" %>
The syntax for these tags assumes that you have specified the c prefix in the taglib directive. If you specify a different prefix, use the prefix you specified in place of c in the tag syntax.
