JSTL Core <c:set> Tag
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.
Attribute:
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.
Example:
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<html>
<head>
<title><c:set> Tag Example</title>
</head>
<body>
<c:set var="salary" scope="session" value="${2000*2}"/>
<c:out value="${salary}"/>
</body>
</html>
