HTTP Status 404 - /FirstSpringMVCProject/WEB-INFHelloPage/.jsp

I am trying to learn the spring mvc framework but when I try to run the code underneat on the server, I am not getting anything rendered also only the error in the screen shoot. But I have noticed that the url has the following WEB-INFHelloPage/.jsp in the 404 error. Is that normal (also wihout backslash between WEB-INF/HelloPage.jsp)? And Why am I not getting something as:

First Spring MVC Application Demo

Hi user, welcome to the first Spring MVC Application

rendered?

The error is explicit about that: you forgot the ending / in prefix property. It should be:

...
<property name="prefix">
            <value>/WEB-INF/</value>
        </property>
...

But with a decent version of Spring MVC, you have no reason to use an explicit BeanNameUrlHandlerMapping nor derive you controller class from AbstractController. Those were for Spring 2.0, but since 3.1 RequestMapping annotated methods are both more powerful and simpler to use.
