Spring MVC. HTTP Status 404

I began to learn "Spring MVC" from this course: http://www.pluralsight.com/training/Courses/TableOfContents/springmvc-intro
At step "Building->Run the Application" I'm stuck.

When I try to go to link

http://localhost:8080/FitnessTracker/greeting.html

I get "HTTP Status 404"

HTTP Status 404 - /FitnessTracker/WEB-INF/jsp/Hello.jsp
type Status report
message /FitnessTracker/WEB-INF/jsp/Hello.jsp
description The requested resource is not available.
Apache Tomcat/7.0.50

- it's work (file: webapp/index.jsp)

Answer

The error message says that it's looking for Hello.jsp. And indeed, your controller returns the following view name: "Hello". But your screenshot shows that your file is naled hello.jsp. The case matters.
