<c:set> Tag

JSP Standard Tag Library

The <c:set> tag is used to set the value of variables and object properties.

The <c:set> tag is akin to the <jsp:setProperty> action tag's twin.

This tag is particularly useful because it evaluates the expression's value and then uses the result to set the value of a JavaBean object or a java.util.Map object.

Syntax

&lt;c:set
   var="<string>"
   value="<string>"
   target="<string>"
   property="<string>"
   scope="<string>"/>

Attributes

The <c:set> tag has the following attributes:

Attribute Description Required Default Value
value The value to be stored No Body content
target The object whose property is to be modified No None
property The property to be modified No None
var The variable to store the information No None
scope The scope of the var attribute No Page

If the target attribute is specified, the property attribute must also be specified.

Example Demonstration

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<html>
<head>
<title>c:set Tag Example</title>
</head>
<body>
&lt;c:set var="salary" scope="session" value="${2000*2}"/>
&lt;c:out value="${salary}"/>
</body>
</html>

The output is as follows:

4000
