Passed Part 2/3

Well I passed it. Pretty suprised looking at the results and where I lost marks.
Dropped 1 on my class diagram which over the long month I'd been waiting for my result I decided really sucked and would probably cause me to fail. But hey it got 43.
Lost none in my Sequence which i'm glad about and did really work hard on. But I did use some non uml constructs for if-else if-else provided by Together J.
Lost most of my marks on Component, now I dont really understand this since my component diagrams were almost ditto copy of the SCJEA Guide component diagrams. I used J2EE Sterotypes and worked pretty hard on these ..
Oh well not really happy with the result since I have no constructive idea why they think my component diagram sucked major ass .. maybe someone here will offer to review it for me.
I think the people at sun have a check list of things they look for and mark off what ever they find giving marks for things. I must have missed some things off!
Anyway I submitted
1 Class Diagram
3 Component Diagrams
8 Sequence Diagrams (only the 4 use cases but chopped diagrams to keep them small)
Changed the domain model cos I really couldn't accept it in its current form. Only changed it slightly. Followed the web controller - session controller pair combination as outlined in the blue prints.
Any ideas on what they expected in the component diagram???

If you passed, why worry?
When you do a real project, you're one day going
to think, if I moved this from here to there
this would all work a little smoother. Or maybe,
you'll think, I could reuse this component on a
different project too, if I moved this class.
Head for the pub, buy a new frame for your
certificate, and enjoy the day.
Congrats on your achievement, you are SCEA.

hi Jas,
would you kindly share with us on how you approach the design? What is the sequence of your designing steps?

Well I started out working on mainly the sequence diagrams trying to get the use cases to fit. I did initially do some activity diagrams but was unhappy with that approach. While on the sequence diagrams I discovered patterns, classes and components (JSP, VOs, EJBs) etc to satisfy my design. Then I just worked on all three concurrently until I was happy.

well, it really seems the is some degree of arbitraryness involved in the marking. I had to re-submit my exam once because I lost too many points on my first class diagram. However, I had 12 pts (100%) on the sequence and 42 on the component diagram.
The resubmission was identical with the exception of an enhanced class diagram. However, the resubmission results showed 7 pts for the sequence and 37 for the component diagram (along with 40 for the class, which made me mass - puh).
So the exact same sequence diagram gave only little more than half the score on the second submission...

Is there a good EJB design book that would be useful for Part 2/3?

My design was pretty much ejb neutral and you could use both but I did advocate the use of EJB2.0.
The best books I found were
1) EJB Design Patterns from the Server Side
2) UML Patterns by Craig Larman
I agree. Here's the link:
