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.
Apache Tomcat/7.0.50

    public String sayHello (Model model) {
        model.addAttribute("greeting", "Hello WorldX");
        return "Hello"; 
    }

http://localhost:8080/FitnessTracker/ - it's work (file: webapp/index.jsp)

Have you tried with the commented version of the InternalResourceViewResolver? — Kevin Bowersox

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>

When you hit http://localhost:8080/FitnessTracker/ , it search for index.jsp file and return it. But when you hit http://localhost:8080/FitnessTracker/greeting it will search for file named "Hello.jp" because you are returning Hello in the controller method. But the file name is "hello.jsp". Note that it is case sensitive. So that was your mistake. You have to retun hello rather than Hello. It should work fine after that.

@Controller
public class HelloController {

@RequestMapping(value = "/greeting")
public String sayHello (Model model) {
    model.addAttribute("greeting", "Hello WorldX");
    //return "Hello"; 
    return "hello"; 
}
}
