Spring MVC. HTTP Status 404

java spring jsp spring-mvc model-view-controller

34,701

Solution 1

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.

Solution 2

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"; 
    }
}

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
