Eric --
I believe servlets just act as a glue connecting your business logic with
the presentation. The actual HTML *generation* classes should be clearly
de-coupled from the servlet logic. HTML generators can talk back to the
business objects, get data and generate to any presentation FE which
requires it - either browser / MS application as you said.
Strictly going by the 3-tier architecture kinda confuses one here. Servlets
are not the exact controllers. Infact the HTML generators can be ! Model is
your business objects and the view you want it to be. I wonder if there is
some layer in the architecture we can name - which does the same function as
the servlets. May be, negotiator ?
Just my $0.02 ..
