Within a <c:param> tag, the name attribute indicates the parameter name, and the value attribute indicates the parameter value.

JSTL <c:param> Tag Example:

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

<body>
<c:url value="/footer.jsp" var="myURL">

   <c:param name="employeeName" value="Dinesh"/>
</c:url>
<c:import url="${myURL}"/>
</body>
</html>
