Class diagram for Part II in Mark Cade and Simon Robers's Study Guide

HI,
I just got the book and found the class diagram
in the case study is very simple. It includes
a modified domain model and three EJBs. My question is why there is no controller servelet.
What is the general guideline for class inclusion?
Thanks.

I would say the controller servlet belonged in the component diagram, not the class diagram.
I'm interested to know what Mark has included for Part II (I've not seen the book) in his book. Could you give us a quick run through Jim?

Simon,
The Part II is for an online ordering system
for web clients only. Customer does something
like selecting items, creating order, and paying
the order. The solution includes a layer map, a tier
map, one package diagram, one class diagram, three component diagrams,
and two selected sequence diagrams.
The reason that servlet controllers were not
included is that the servlets do not define
business rules. Am I right?
What if my login use case needs a servelet
controller to perform login?

Do they provide good Component Diagram examples? I would love to know what they look like.

I have the study guide. My take on the component diagrams is for example - what is in a WAR file for servlets/JSPs. These are the components you could distribute to various web containers.

I checked out the Study Guide today and the Component Diagrams didn't have any packages. They were very simple. It think I am ready to just submit my assigment and see how it turns out.
