Hi Wes, thanks for the post.
I like the idea of being able to decorate screens differently depending
on device without changing much existing code and I can see a use to
this for example for pages being given a different footer to provide
device specific links or adding side menus for devices with enough
screen space. (The main focus of my web pages are application GUI rather
than content). I do intend to look into sitemesh but I know nothing
about it as yet. However, what sitemesh (I don't think anyway) cannot do
is for example, for an old blackberry that does not support html tables
very well, allow me to render a list of results in a business card style
layout instead of a four column table - if it can then I'd be glad to
know how and investigate it's use further as it would solve some of the
problems I encounter.

covered the answer already, but...
Have you looked at Sitemesh? I would suggest look at creating
different decorators for each of the devices you want to support, then
code your undecorated JSPs so that they can be decorated based on the
device accessing it. Sitemesh has a ton of different ways you can pick
the decorator, so I would imagine you'd be able to find a way to
abstract the decorator picking logic outside of your business logic.
Then, the advantage of the decorator pattern is that you can code your
UI screens and business logic once and just have the screens decorated
differently based on the abstracted decorator picking logic. (As a
bonus, you can add new decorators for new devices without changing
much)
