JSTL Core tag – set() : Function

The <c:set> tag is JSTL-friendly version of the setProperty action. The tag is helpful because it evaluates an expression and uses the results to set a value of a JavaBean or a java.util.Map object.


The <c:set> tag has following attributes:

Attribute Description Required Default
value Information to save No body
target Name of the variable whose property should be modified No None
property Property to modify No None
var Name of the variable to store information No None
scope Scope of variable to store information No Page

If target is specified, property must also be specified.

JSTL Example :

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

<c:set var="num" scope="session" value="${1234}"/>
<c:out value="${num}"/>
