model.addAttribute("msg", "Hello world buddy");

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt"%>
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions"%>
<%@ taglib uri="http://www.springframework.org/tags/form"
prefix="springForm"%>
<!DOCTYPE html">
<html>
<head>
<title>Spring MVC -HelloWorld</title>
</head>
<body>
<springForm:form name="hello" commandName="command" method="GET"
    action="/hello">
    <c:out value='${msg}' />
</springForm:form>
</body>
</html>

but i am getting output

It also happens to me, in my case my solution was to correct the pom.xml, just verify that your are using the correct version of jstl. This is the pom.xml that I use:

pom.xml

        </plugins>
    </build>

        </dependency>
        <dependency>

            <artifactId>jstl</artifactId>

        </dependency>
    </dependencies>
</project>

Clean all maven repository
Reload all the dependencies from maven, if you are using eclipse go to righ click to the project select maven and update project.
The example of the pom.xml that I used maybe doesn't have all the dependecies that your are using, but it can give you an idea if your jstl dependency is correct.
There are other post related to this issue, it depends to many reasons, in my case was just the maven dependency.
