add.jsp
<%@ page contentType="text/html" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<head>
<title>JSP calculation</title>
</head>
<body bgcolor="cyan">
<h1>Calculation through JSP is as </h1>
1 + 2 + 3<c:out value="${1 + 2 + 3}"/>
</body>
</html>
mul.jsp
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<html>
<head>
<title>Multiplication Examples</title>
</head>
<body bgcolor="cyan">
<h3>Out Example</h3>
10 * 45 =
<c:out value="${10*45}" />
<br />
</body>
</html>
Step 7: Compile and Run the application.
Now we compile the application and then run it on the server and find the following output.
Output
