Looks OK so far.

Umm... you get that in the *browser*? The browser should never ever
receive FreeMarker tags and interpolations, as those should be
resolved on the server.

If the output indeed contains ${...} stuff, then the templates are not
processed by FreeMarker at all, but are served like static files. That
means, there is something wrong with the your HTTP server or
Servelet-related setup. What URL do you enter into the browser? You
shouldn't ever visit .ftl-s directly, as they need something that
prepares the data-model, this being an MVC template engine. If you are
using JSP-Model-2-like setup, please see:
