[Sun qinlong]

hello everyone:
except that I have the same problem as many of you .I have another problem that in my assigment the full mark is 400.what about you ??/
sun email to me that I can download a new assignment once aggain till april 2ed . but I can't do that now !!

[Andrew Monkhouse]

Interesting. My project, which I downloaded on 25 March, only has 155 marks. Namely:
General Considerations (Total 58)
Ease of use (23)
Coding Standards (23)
Clarity and Maintainability (12)
Documentation (Total 20)
user (10)
javadoc (5)
Comments (5)
User Interface (Total 24)
Good Human/Computer Interaction (24)
Server Design (Total 53)
locking (30)
error handling (8)
search algorithm (15)
Feel like explaining where your points are allocatted?
Regards, Andrew
PS: Hello everyone. I am very new here. Just starting my assignment, and only recently found out about this site.

I just downloaded my assignment yesterday and the new marking scheme now looks like this:

Marking Criteria
Your work will be evaluated based on the following criteria. The minimum passing score is 320 out of a possible 400 points.
General Considerations (100 points)
Documentation (70 points)
Object-orietned design (30 points)
User Interface (40 points)
Locking (80 points)
Data class (40 points)
Server (40 points)

Data class (40 points)

Alex,
I am curious, does your version of assignment instructs you to define the lock/unlock methods in the Data class?
Eugene.

[Alex McLachlan]

I am curious, does your version of assignment instructs you to define the lock/unlock methods in the Data class?

It does - the data access class (Data.java) must implement the interface DB, which contains (amongst others) these two methods:

public long lock(int recNo) throws RecordNotFoundException;
public void unlock(int recNo, long cookie) throws RecordNotFoundException, SecurityException;  

Alex.

[Andrew Monkhouse]

In case anyone else is interested in what is being emphasised / de-emphasised in the new marking:
Still 80% to pass.
Gerneral considerations was 37% now 25%
Documentation was 13% now 18%
User Interface was 16% now 10%
Locking was 19% now 20%
Server was 15% now 10%
New:
Data class 10%
Object Orientated Design 8%
I am glad user interface has gone down in importance.

public void unlock(int recNo, long cookie) throws RecordNotFoundException, SecurityException;

Aha, that's something completely new, -- now a cookie is supposed to identify the client? I suppose Sun is pushing for a particular design so that it is easier for them to grade the solutions.

yep, and i dont know if marking was always like this, but based on the following i can see how the cookie and the data class being implemented in that way makes it easier to grade the solutions.

The marking is done in three phases. First, software checks that overall structure and nomenclature conform to specification. Second the examiner runs the code ensuring that it functions correctly through the specified operations. If any automatic failures are noted at this stage, the marking process terminates and the assignment is failed.

Hi,
Would you mind to tell us more about the implementation? I don't know how to generate the unique cookie for lock method.
Cheers,
Michael

Hi,
When I first downloaded my assignment there was no database and the interface DBAccess had cookies. Later on they replaced the assignment and now it has the interface DBMain without any cookie.

my new assignment no longer has a cookie, except for the magic cookie value which identifies the files as a data file, but that has nothing to do with the previously mentioned cookie.
are you sure you're using you're new instructions file?

[frank sun]

I also don't have a cookie file, so where can I find the magic number? and how?
best regards!

My DB interface has those cookie for lock/unlock/write methods. My intstruction file hasn't changed since first I downloaded. Did yours change? I hope there is no cookie for those methods.

You can open your given db file with any hex editor and you can locate the magic number (just follow your data format instruction). Mine is 0x00000202.
