Your DispatcherServlet is mapped to *.htm:

<servlet-mapping>
    <servlet-name>FreedomSpring</servlet-name>
    <url-pattern>*.htm</url-pattern>
</servlet-mapping>

But you are accessing the controller through non-matching URL: http://localhost:8080/FreedomSpring/hello. You have three choices:

1. Change you dispatcher servlet to:

   <servlet-mapping>
       <servlet-name>FreedomSpring</servlet-name>
       <url-pattern>/*</url-pattern>
   </servlet-mapping>
   

   but in this case all requests will be handled through the Spring MVC, including images and other static resources

2. Use extension in controllers as well:

   <url-pattern>/*.htm</url-pattern>
   

   and map Hello controller to .htm so that you use: http://localhost:8080/FreedomSpring/hello.htm.

3. Map controllers to a different subdirectory:

   <url-pattern>/mvc/*</url-pattern>
   

   to access them you will have to use: http://localhost:8080/FreedomSpring/mvc/hello without making any changes to the controller itself.
