Spring MVC. HTTP Status 404
Question
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.

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.

Try returning the properly cased view name which matches the JSP hello.jsp from the controller. Currently the controller returns Hello while the JSP is named hello.jsp , causing the 404.
@Controller
public class HelloController {
@RequestMapping(value = "/greeting")
public String sayHello (Model model) {
model.addAttribute("greeting", "Hello WorldX");
//return "Hello";
return "hello";
}
}

Change in your web.xml the to
<servlet-mapping>
<servlet-name>fitTrackerServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
