Hello All,
Today my status was changed to pass after my re submission on 07/16/08. I am so happy today. Here is the break down. Initially i was failed due to a flaw in the locking code.

The maximum possible score is 400; the minimum to pass is 320.
General Considerations (maximum = 100): 100
Documentation (maximum = 70): 70
O-O Design (maximum = 30): 30
GUI (maximum = 40): 24
Locking (maximum = 80): 80
Data store (maximum = 40): 40
Network server (maximum = 40): 40

Total score Achieved = 384/400.

Can you explain a bit more on the flaw and what you did to fix it?

Jethro,Kah,

My locking was not up to the spec during my first submission. I have not used the object.wait,notifyall at all. My lock and unlock methods had nothing but add or remove the records from a collection(no wait,notify).

During my second submission, i have moved my locking from client to the server side. used object.wait and notifyall. I have read many threads about locking and got the idea of how to do it.
example
synchronized(lock){
while(isLocked(recNo)){
try{

lock.wait();
......
....
}

I hope i answered your questions and good luck to you all.
