After 2.5 months of hardworking, I finally get what I deserve. Once again, I have to give special thanks to Matt, Adrian, Lisa, Sam the ex-moderator and others which I have forgotten the name. The group discussion helps a lot in justifying the design. I have really learnt a lot of technical stuff from this forum. I will be working towards SCEA from this point on.

You DO deserve it and congratulations! Well done. You will be an inspiration to all of us. If you deem it worthwhile perhaps you could share with everyone your scheme....no specifics....but
1.) when you submitted, how confident were you?
2.) is it just me, or after you submitted did you say to yourself,
i should have done this, I should have done that.?
3.) did you find the follow-up exam challenging?
4.) what are your future plans?
5.) i have just submitted ( not taken exam yet )...
I graded myself...I'm just curious...did you grade yourself
and how close to the actual grade was your self-evaluation.
I'm finished looking for advice (I hope), but I know from personal experience that a lot of people would appreciate it if you would stick around and provide your insight ti those struggling.
Congrats Rudy.....wish you all the best.

With Respect,
Matt

Matt,
1) I am 90% confident with my assignment. The 10% I am worrying about is that my assignment might somehow not be working properly in their Solaris/Unix because I develop the assignment on Window ME platform. To play safe, I completely follow the installation document written by myself to install the FBN program to make sure the document does not miss anything.
2) Yes, I have the same statement as you have after the submission. I should have done this and that. But this is not a problem at all.
3) The follow up exam. basically tests that you know what you have done. If you steal the assignment from someone, you may not be able to answer the questions specific to the assignment because they are all design oriented.
4) Probably go for SCEA. It seems that EJB, servlet and XML are the next bunch of stuff I have to get familiar with. I have a feeling that only having the Java skill set is not enough. It has to come with other web related tools
5) I do not grade myself personally before knowing the result, but I am happy with the grade I achieve.

Rudy,
Congradulations for your success. I am in the middle of the way to finish my assighment.
You know the Data class has 2 constructors. I have not seen I need to use the 2nd one. Could you tell me when I need to use it or I do not need to use it.
Thanks
Ruilin

luis:
The business logic of flight booking is on the server side. I just provide a flight booking service to the client in the form of a remote object, and I only have one remote object in my program.
ruilin:
I am not sure about your assignment. But for mine, the other data constructor is for creating a blank database. Obviously, that one is not for use in the project.

congratulations rudy
i am much concentrating your replies in this forum.. it was really technical and more informative.
i have a question .. i have mostly finished my assignment, but i have doubt in concurrunt access. when i test my program with 3 host, 1st host it gives answer "succefully booked, 2nd gives " no seats available" but 3rd machine hangs. i am confused much . what is the reason.
i created only one remote object.in my locking logic is
i use vector
synchronized (vector)
if record is there
wait()
else
add elemnt to the vector
is this a correct logic for locking?
pls. could you me a reply
regards soundar

Would you please tell me, as I am doing my assignment and implementing the criteriaFind method
my structure of criteria is
<field name>=<field value>
eg. Origin Airport=SFO
but not the kind in the example in the instruction
but I think it is more likely to be in the form
<field name>=field value>
am I right? And What is your structure.
Also I have implemented logging for actions taken
Should I remove it? or If I don't. will I be penalized???
One more is I inherit the Data class instead of modifying it?
What's your idea on this? And Why???
Regards and thx for your kindly attention

Soundar: I guess you are encountering the deadlock situation or your client somehow is never waken up after being put into the thread pool. You have to debug your recording locking and unlocking mechanism. Do you rememeber to remove the lock after database updating?
Alex: Yes, you are right. IMO, your logging feature should not be penalized. I have the logging feature too for my server, but it logs it to the screen instead of a file.
ruilin: Just you a case statement for the local and network connection modes.

Thx a lot, I would like to ask a question about modifying or extending. As I am really afraid. My friends have read my codes and they said they never agree my method to enhance the Data class by extending it
They said they will just modify it for convinence
But I think there may be other implementation for criteriaFind or locking for other developers, I think I'd better extending it and just call the basic features of the base class
One more question is my criteriaFind constructs criteria without single quote in the values part but just fieldname=fieldvalue
do U think it will be penalized? To my understanding it uses
<fieldname>=<fieldvalue> in the instruction then I use it in this way. Would U please help me to solve these problems
Am I doing in the right way??? THX for your help and best Regards

Sorry one more question, can U tell me your project package layout as I have no layout for the class files now and just centralizing it in a single package
Should I separate them and how should I do it?
THX
