Hi Vincent,

The diagram implies Model View Controller with the labels but as you
said it's not attempting to describe MVC per se. Not a big deal, the
diagrams are clear and simple in terms of describing the structure. 

As far as the argument, I was trying to convey that there is a lot of
confusion about MVC that never seems to be clarified. I see the three
tiers as a data model, a constrainted view of that data model (the view)
and something that drives the code that creates the view (the
controller). JSPs, Servlets are a front-end for control and view
elements. MVC is a good architecture whether you hook up a GUI or not.
If you don't, you've still got a "view" which is why IMO the JSPs are
independent. Anyway, it's way off topic from cactus:)

Actually we're not even trying to describe the MVC architecture. It was
just a convenient way to explain all the places where Cargo could help
in testing.

I'm not sure I understand your argument but if you want to submit a
better image, we'll happily replace this one with yours.
