I don't believe you would make requests on the controller for generating
degenerate views (views with no parameters). In general, the views handle
themselves without interactions on the controller, unless the user is
affecting the data in the model. Remember that the controller's role in MVC
is to manage manipulations of the data, e.g. changing user passwords, etc.
To handle the authentication part, think of logging into the system as an
MVC pattern applied to the session object. You would need a
"SessionController" servlet to which you would post credentials and set the
session state.
Also, the view retrieves data from the model directly in a read-only role.
This is typical behaviour for a view in MVC, otherwise it can't act like a
bona fide view of the model! :) Just remember to ONLY act in a read-only
role with the model from the view.
Since this is a design pattern topic, it should probably go to another
mailing list ...
Please correct me if I missed something ...
