I just received my results for the SCJD and I would like to thank everyone in the Developer Certification forum for their help. I received a score of 145/155. The break down was General Considerations(maximum = 58): 55 Documentation(maximum = 20): 20 GUI(maximum = 24): 21 Server(maximum = 53): 49
I chose to use RMI over serialized objects. I modified the Data class instead of extending. I implemented client-tracking for locking within a DataProxy class and implemented the actual database locking within the Data class. I used the Unreferenced interface to handle the release of locks for crashed clients. Design patterns I used included Factory, Proxy, MVC, and Data Access Objects and Value Objects for the persistence layer.
Thanks again to everyone for their help. On to SCWCD!
Regards,
Graham

Well done, Graham.
Can you tell us in brief how you prepared for the whole examination?

Thanks for the congrats Clement.
It took me about 2 hours to prepare for the follow-up examination. I reviewed my source code at a high-level and drew up some UML diagrams to review how the classes fit together (the diagramming was probably overkill but I am a very visual person). I then re-read my design document to review my design decisions (this was probably the most helpful).
The follow-up exam is dead easy once you've done the assignment and necessary documentation. It's more or less an exercise in proving that you actually did the work.
Regards,
Graham

Congratulations Graham! One questions, when did you submit your assignment and take your essay exam? I uploaded last Thursday, and still waiting.
Good luck on the SCWCD, thats what I'm working on now also.
Mike

Hi Mike,
I uploaded my assignment May 30th. I took my written exam on June 3rd. I received my results on June 19th. Sun claims that the marking process should take about 4 weeks from the time you take your written exam (that's assuming that Prometric sends Sun your exam promptly). The grading of your assignment will not begin until you've uploaded your assignment and Sun has received your written examination from Prometric. In my case, the process only took a little over 2 weeks. If you are worried about a mix-up you may want to write Sun and ask them if they've received your written examination yet.
Best of luck Mike!
