JSTL Core c:set Tag
The JavaServer Pages Standard Tag Library (JSTL) encapsulates core functionality common to many JSP applications. Instead of mixing tags from numerous vendors in your JSP applications, JSTL allows you to employ a single, standard set of tags. This standardization allows you to deploy your applications on any JSP container supporting JSTL and makes it more likely that the implementation of the tags is optimized.
Below is the syntax to include JSTL Core library in your JSP for JSTL Core c:set Tag :
<%@ taglib prefix=”c” uri=”http://java.sun.com/jsp/jstl/core” %>
