problem with jstl code in spring application

Souranil21 chakraborty · March 3

so i am getting this error while trying to return a .jsp page and keep getting this error but if i remove the ${result} the page is displayed fine.

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1" isELIgnored="false"%>
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Addition result</title>
</head>
<body>
    <p>The result of addition: ${result} </p>
</body>
</html>

Any idea why this is happening ? am i missing some dependencies?

Been a hot minute since I've seen a JSP, but my guess is that your result is null. You may need to add the JSP equivalent of an If or make sure that result is initialized before the page is sent to the user.

I could be 100% out to lunch on this though.
