Spring Web Application - The requested resource is not available

I would like to ask you for an advice what could be wrong with my easy tutorial example of spring web applications.

I am trying to reach website on this URL:

http://localhost:8084/SpringTutorial/hello

As a response to this URL I get HTTP 404 - Resource not available - from apache tomcat server.

Here is the code:

web.xml

<?xml version="1.0" encoding="UTF-8"?>
    <web-app version="3.1" xmlns="http://ift.tt/19L2NlC" xmlns:xsi="http://ift.tt/ra1lAU" xsi:schemaLocation="http://ift.tt/19L2NlC http://ift.tt/1drxgYl">

        <servlet>
            <servlet-name>spring-dispatcher</servlet-name>
            <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
            <init-param>
                <param-name>contextConfigLocation</param-name>
                <param-value>/WEB-INF/spring-dispatcher-servlet.xml</param-value>
            </init-param>

            <load-on-startup>1</load-on-startup>
        </servlet>
        <servlet-mapping>
            <servlet-name>spring-dispatcher</servlet-name>
            <url-pattern>/</url-pattern>
        </servlet-mapping>
    </web-app>
