JSTL Core <c:set> Tag

JSTL Set tag is used to create new variable and assign a value to new or existing variable.

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.

JSTL Set Tag Example,

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<title><c:set> Tag Example</title>
<c:set var="salary" scope="session" value="${50000*2}"/>
<c:out value="${salary}"/>

As you can see above, in the set tag, new variable "salary" is created and value is set to 100000. In the next line, it prints the valued of salary variable using out tag.
This would produce following result:


The <c:set> tag has following attributes:

valueInformation to saveNobody
targetName of the variable whose property should be modifiedNoNone
propertyProperty to modifyNoNone
varName of the variable to store informationNoNone
scopeScope of variable to store informationNoPage
