congratulations let's celebrate
Thanks guys
No idea where I lost points, I included JSPs in the component diagram, it showed the separation of layers and J2EE patterns very clear. I also used stereotypes for every asociation.
Probaly they didn't like that the diagram was quite big in size.
Finally the ruslts arrived:

Thank you for the interesting discussions, and the great learning exerience.
I took part III test on Sept. 3 and received the results on Oct. 1.
My solution included one slightly extended class diagram, one single huge component diagram from the web client perspective one smaller component diagram from the fat client perspective and 12 sequence diagrams.
Key to solvng the asignment was to get a good understanding of the flight busines including a solid data dictionary ablut all the terms used.
It took 60% of the time to get this understanding and 40% to create the documentation.
Thanks and good luck
Yes, it's Test History right above the SCJP results. It took 3 weeks from the written exam until the results showed up.
Congrats, Matt!

Hi Cathy

I am using the system time (in milliseconds) to identify the client

Well there is still a small chance that two clients may receive the same Client Id so there should be a better solution that is 100% bullet proof.
One solution could be a Factory that uses a singelton cbject to hand out 'access instances' in a synchronized method. Each handed out access instance has an implicit id ar can be assigned an explicit one on handout time.
Hi, after waiting 3 weeks today the results arrived
Thank you all for your help and for the interesting discussions we had.
I took the follow up exam on Jan 10.
Test: Sun Certified Developer for the Java 2 Platform (310-027)

Grade: P
Score: 145

The maximum possible number of points is 155; the minimum to pass is 124.
Section Summary Report:
General Considerations: Maximum=58 Deductions=0 Actual=58
Documentation: Maximum=20 Deductions=0 Actual=20
GUI: Maximum=24 Deductions=0 Actual=24
Server: Maximum=53 Deductions=10 Actual=43
Total: Maximum=155 Deductions=10 Certification Score=145
A few words about my solution:
For the client and the server I used named parameters (so they seem to accept them):
java -jar client.jar flights=db.db host=localhost port=1099
java -jar server.jar flights=db.db host=localhost port=1099
The GUI employed application level MVC and I tryed to follow the Java Look and Feel Guidelines.
Busines logic was encapsulated in a class named TravelAgency and acted as the Model in MVC.
The server used RMI, a factory method that handed out one Remote instance per client and a encapeulated LockManager.
Good luck Cowboys and Girls and thank you
I'm heading for SCEA now...

Well, I'm not Peter,
but here come mt $0.02:
The data class relies on the first colum to be uniue i.e. this is the unique primary key.
That's a perfect qualification for identifying a record.
As long as you can defend your design I think any solution (almost) can be ok. Just state it in your design document.
I have choosen to extend the data class to add/ modify it's behaviour.
