Thanks for the reference Craig; but unless I'm mis-reading you, that
still leaves me with data lookup 'hard coded' in Java classes. My goal
is to be able to change a page's data requirements without
recompilation. I'll take a look at Shale though and see if it has
anything to help in that context.

Laurie,
(Sorry for the late response -- just getting back from vacation).
You might want to take a look at how Shale approaches your "pull" requirement.
http://wiki.apache.org/struts/StrutsShale/
Being JSF based, Shale encourages you to associate a single bean with
each JSP page, where the bean can have more than one behavior (versus
a Struts 1.x action where the only behavior is to process the submit).
In particular, Shale supports a prerender() method that can be used
to pull the data that this page "knows" it needs from the model -- and
it sits right next to the logic (in a separate method) that processes
the subsequent submit. In Struts 1.x terms, prerender() is where
you'd do the things you currently do in a setup action, while the
normal event handling method (called an "action" in JSF parlance, but
it's a method instead of a class) does the follow-up updates to the
model.
In Struts 1.x, you see this same idea directly implemented in Tiles,
via the Controller interface. It's also a dominant idea in ASP.Net,
Tapestry, and Spring MVC -- and it's sorta immortalized in the J2EE
design patterns lexicon as the View Helper pattern.
I'd be interested to hear if this is close to what you had in mind, or
if it was something else again.

I think I'll drop the topic now, before this degrades into a flame fest.

I believe the point was nothing like this at all, Dave. Don't know
why you thought it was. Seems like you just thought this stuff up
separate to me. However, certainly I don't think that the issue
whether or not you are writing a CMS is relevant to the issues
discussed. I also have no idea why you went off on the XML stuff.
This is simply an issue of where work on the model should be. Your
discussion, so far as I can tell, is about something entirely
different and I have no idea where you got these issues. If these are
the issues, then you must be speaking some language with Ms. Harper
that I don't know.

Just use some framework, like Struts. Write your actions and your
model to take are of this business and feed the data to the
appropriate scopes and objects.
I believe the point was that this isn't an option.
