How to use JSTL in JSP

JSTL is developed by java people as part of  the JEE API. But to use JSTL in our JSP pages, we need to download the JSTL jars and we need to add jar into WEB-INF/lib directory.

JSTL has some JSTL Core Tags and JSTL Functions. Before writing any JSTL Core tag or JSTL function  into JSP page we need to add tag library into JSP page Header section.

JSTL Core Tags library

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

JSTL Functions Tag library

<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>
