It sounds like you haven't read:

    <http://jakarta.apache.org/turbine/fsd.html>

So, let me explain:

You have 4 "UI" Modules:

    Page, Screen, Navigation, Layout

Screen is considered the "body" of the content you are trying to deliver.

If you think of the Modules as objects within each other, the Screen and
Navigation is contained in the Layout and the Layout is contained in the
Page.

This is illustrated here:

    <http://jakarta.apache.org/turbine/images/ModuleObjectLayout.gif>

Now, when you combine things with Velocity, you also need to factor in a
directory structure. All of that is described here:

    <http://jakarta.apache.org/turbine/velocity-site.html>

Now, a Navigation module is just like a Screen or Layout module.

If you want to include another navigation template into your page, you just
use the $navigation variable. If you want to include other templates, you
can also use the #parse/#include Velocity directives.

thanks,
