hi all..
I have passed the SCJD with a score of 145/155. Although, I've posted few queries in this list when i was at the end of submission of fbn. where i had to make few changes to my design .thanks to Rick Fortier suggestions which helped me a lot.
here are the scores..
General Considerations(maximum = 72): 65
Documentation(maximum = 10): 10
Object-Oriented Design(maximum = 6): 6
GUI(maximum = 20): 17
Data conversion program(maximum = 10): 10
Server(maximum = 37): 37
my design...
1. Modified the Data class
2. Didn't modify the lock and unlock signature
3. Command-line Conversion Tool
4. Used RMI
5. Extended AbstractTableModel

Just remember, meet the specs of the project and document what you did. Not in rediculous detail.
Even if u have your short comings in your FBN do document it in your design doc.Make ur readme.txt as clear and simple as possible.document all the classes there location and a small explanation that helps.
The written exam was a piece of cake, and took me 30 minutes. If you have the assignment fresh in memory you just can't fail.
I wish you all good luck with your certifications

Hi Baiju,
Cognate for such great score.
Can you guide me in locking.
I have simply used Hashmap.
R_Lock = new HashMap(); // THIS IS FROM ANOTHER singleton CLASS

while(R_Lock.containsKey(new Integer(recno))){
try {
BUT to my surprise everyone in this group uses :
private Map lockTable = Collections.synchronizedMap(new HashMap());

Can you guide me where am I wrong? Is not Hashmap threadsafe ?
Or my design is all right.?
I am worring about this point as my assignment says "server shuld be thread safe..." . Is my design (shown above) thread safe ? What comments u had written to show your server is thread safe?
I realize my question is big. but hope you will reply me
Thanks in advance.
I agree. Here's the link:
