Hi,
If you just need login then you can use the Form Based Login (FBL)
feature of Servlets and leverage the web container to do authentication,
so you dont need to write code . If you need login and also
self-registration where users can *create/manage* their own accounts,
then you need to do programatic authentication and need to write your
own code(or leverage an open source library).
If you want an architecture that is EJB-centric then petstore login &
self-registration process design may work for you.
You might want to look at the Adventure Builder instead since it has a
non-EJB design which uses DAOs for its model data and for
self-registration & login process. This will probably be a better fit.
Ther latest version of Adventure Builder is at
https://adventurebuilder.dev.java.net/ and there is an document
discussing the basic architecture of the web application at
http://java.sun.com/blueprints/code/adventure/1.0/docs/architecture.html
hth,
Sean
