Except that that's not just a "Hello Word" page.<p>That's routing to the right page, transaction and session control, storing the text of the message in a separate class than the one that returns the response, and using a template to return the resulting HTML.<p>Looking at the section with the actual example code in it, you could do it in about half that, if you wanted a simple version that just returned "Hello World".<p>If you don't want routing, templating, separation of concerns, etc. then you wouldn't be using a framework like that, of course.
