Could not resolve JSTL dependency - Tomcat 500 Internal error

I am currently trying to work with JSP/JSTL on Tomcat with Spring MVC. As *.jar dependency I tried the following ones:

web.xml (first few lines)

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
        version="4.0">

the jsp file:

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>
<html>
<head>
    <title>Student Confirmation</title>
</head>
<body>
The student is confirmed: ${student.firstName} ${student.lastName}
<br><br>
Country: ${student.country}
<br><br>
Favorite: ${student.favoriteLanguage}
<br><br>
OS Experiences in:
<c:forEach var="temp" items="${student.osExperiences}">
    ${temp},
</c:forEach>
</body>
</html>

Use

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>

And not

<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>

See:

https://jakarta.ee/specifications/tags/2.0/jakarta-tags-spec-2.0.html#multiple-tag-libraries

If that alone did not not work, also add this dependency (remove the others):

<dependency>
<groupId>org.glassfish.web</groupId>
<artifactId>jakarta.servlet.jsp.jstl</artifactId>
<version>2.0.0</version>
<scope>runtime</scope>
</dependency>
