do i need an average of 85% for whatever certification from Sun that i took?
if i had repeated one of them in order to reach 85%, would i still qualify?
I guess i wanted to know whether each candidate has only one record of test scores, that gets overwritten as you do the test.
I know this is not related to SCWCD, but i'm not sure where to put it, sorry.

is it possible? i would like to use swing instead of awt.Canvas..
I wanted to make an GUI chess game, where the grids and pieces would be drawn onto the Canvas..
Is there a way to do this in Swing?
TIA

I believe there are serveral incorrectly worded questions in the exam. Many have been raised, discussed and even notified Sun. However i don't think Sun removes those questions, so sometimes it's a matter of luck whether you'd encounter those questions in the exam.

Is the logo the same thing as what you get on the pin (cup of java)?. I saw the pin and i was a bit disappointed.. I like the Sun Blue/Lavender and its actual logo..

Thank you all who replied, particularly to Mike and Thomas.
It turns out that i had indeed multple servlet.jars in my environment variable declarations. After removing them and upgrading my jdk to the latest version i was able to install tomcat without much problems.
Thank you again

Thanks for all that replied..
I don't have a current employer...
job ads in my local area ask for at least 2 years commercial experience in java..
I was hoping to do something that follows one of the pasttimes, as i'd be more motivated..
What is needed in an inventory system that the database and SQL statements can't do apart from graphical analysis?

I would say that you'd pass without much of a problem, if you'd like to get less than 5 questions wrong though, perhaps you'd need a teeny bit of luck.. just my two cents.

Hi,
I'm thinking of doing a project that i can showcase to potential employers.
My current idea is to put my collection of comic strips (jpg images) into a database, with a java front end for various search and display options. Does this sound too dull? I am only thinking about stand alone apps at the moment, what would be a good model so that it can be easily extended to a client/server scenario?
I'm never programmed java professionally, only played with it in college and at home. I know a bit about swing, servlet, little on threads..
I'd like to be able to give potential employers a CD that they can browse through which demonstrates my abilities.
Any suggestions would be greatly appreciated.
TIA

Here's one rudimentry explanation.
Say there is a parent class P and a child class C
now consider pp, an instance of P, and cc, an instance of C.
In the assignment pp = cc, the compiler knows cc ISA pp (if you are not sure about this, then search for OO documents on inheritance and polymorphism) Hence it lets this happen.
In the assignment cc = pp however, pp is not a type of cc, rather the other way round. The compiler checks this by looking at the inheritance hierarchy, and since the inheritance tree is as such:
P+
|
|__C
an instance of C is also an instance of P, but not the other way round, hence you end up with the result you see.

Seems like the Exception starting filter for Compression Filter is the first problem, though i just have no clue on what is causing it.

Please, your assistance will be greatly appreciated.

Java_HOME is set to
e:\jdk1.3
CATALINA_HOME is set to
e:\program files\Apache Tomcat 4.0
Tomcat starts fine as i've changed the port number to 80 and i can still see the index page. I cannot access the examples via the links on the index page, however. I kept getting 404.
Your help would be greatly appreciated!

Am i supposed to modify the .xml file that is included in the installation? I cannot run the examples that came with Tomcat. I've got Tomcat_home, Catalina_home and java_home all set.. what else do i need to run the examples?

TIA

Thank you both Fei and Ravi for replying.
I was missing the Tomcat_home environment variable. I managed to get the http://localhost:8080 to come up, but then i tried the servlet link on it i got
Apache Tomcat/4.0.2 - HTTP Status 404 - /examples/servlets/ type Status report message /examples/servlets/ description The requested resource (/examples/servlets/) is not available.
I also have Java_Home set up ( in short my jdk runs fine).. I followed the instruction on the website provided by Ravi and got stuck at that point where my link returned a 404.. ? the examples/servlet directly is there..

Well i emailed them (about the exam, not the certificate) and was not expecting a reply but i did, so maybe you can try too, just find the email on the Sun Education site..
Sorry i couldn't be of more help
