Are you sure that this offer is from SUN?
If not then then pls clarify.


Thanks

Hello Devisri,

Head first Servlet & JSP book is enough for the exam.
If you have experience with Web then you should be fine by just going through the book.Otherwise you have to try some example on tomact that will clear some concept. In my case I have experience so it took me only 4 days. Exam is easy, so if you study well you should be ok. I don't think you need to buy any stest simulator.

Hello,

Yesterday I cleared SCWCD with 91%.
HF book really helped me to pass the exam in relative short time.
Thanks to Javaranch.

Hello Suds


When did you submit your assignment and when did you take the essay test ? I am also waiting for my results and just want to check how much time sun tok to process yours.

Hello All,

From CertManager


Sun CertManager is being transitioned to a new site effective December 10th, 2003. Due to this transition the CertManager tool will NOT be available from Dec 4th 6:00 PM Eastern time through Dec 10th. Please be assured that any exam results from this period will be included in the new Certification Management system.


Why so many people passing SCJD ?

Hello Mickael,
Make version 1.2 instead of 1.0.

But if the submission job itself does not pass, the money invested on follow-up would be in vain and meaningless.
Is that right?


No, u don't have to take follow-up, if u fail.

I have not the weight you and Andrew may have on this forum and it would be a pity that Manoj would lose points in locking just because of my lack of personal conviction power ...


Hello Philippe,
You have great convincing power. The great explanation you provided led me to think about issues which I wasn�t (Code review). Well, I dropped the idea of record level locking and sticking with, what I have. Because what I think, each day I will come up with new ideas (buggy). So the assignment will go for forever.
About vector:
When I started learning JAVA I used vector a lot (in school). So the mind-set was (not now, u changed) use vector for object storing.
By the way I changed all code from vector to arrayList ( was simple one line ).
Thanks a lot

Manoj,
Hi Philippe,
I am glad you replied and you hit the correct point whcih I was thinking.
I need your opinion.
I am almost done with my assignment(coding part, this is what I think).
I have implemented locking mechanism same like most of other folks ( waiting on Vector and again notifying).
Yesterday I re- read instructions and thought I am wrong ( I am ).
So what I am thinking:
Record Object with instance variable recNo and cookie.
I will store it into vector and instead of waiting on Vector I will put thread waiting on Vector(i).wait() (where i is Record object).
Again notifying same thing Vector(i).notify and remove that Record object from vector. ( I love vector, so please no Array[]).
What you think is it ok to do changes at this time and will this solution work.
Please comment.

Hello Bharat,
I know it's logically and physically ( for RAF) works great.
But in case of CPU we can't be sure. So just forget about later(CPU)thing.
Is that right?.

Manoj.


Any attempt to lock a resource that is already locked should cause the current thread to give up the CPU, consuming no CPU cycles until the desired resource becomes available.


Hi,
I don�t think there is any way to implement above specification, which guarantees that thread will come up only when lock is released.
Consider following example:
Thread1 just locked recNo1.
Thread2 comes and lock recNo2.
Now Thread3 comes and tries to lock recNo1, but it is locked by Thread1 so goes in waiting period.
Now, Thread2 unlock recNo2 and notify (notifyAll). In such situation OS may again put Thread3 to run (assume my O.S is dump and there are other threads available to run).

The point here I am trying to make that, the waiting thread gives up CPU time for that period but again come up before the lock actually gets unlocked on desired recNo. So there is there any way that we can specifically invoke specific thread.
Correct me if I am wrong (and probably I am).

Manoj.
Thanks Jim,
You are right those are extra spaces. As I am just using it for validating whether contractor is booked or not. So the triming does not affect any operation.

Thanks a lot.
