Help!! uploaded assignment is corrupted??

Hi all,

I initially uploaded my assignment in early June.
Then when I checked the test history section of
the certmanager site in July,
I had an F saying that the uploaded jar file was corrupted.
It said to upload the assignment again, without additional cost.
So I did, and I checked the site again today,
and it says that the file is corrupted again.
(with a new date for "Test Date")

Has anyone experienced this? What could be the problem?
Could it be that I didn't package the jar file correctly,
or is sun's server giving me problems?

Did you checked if the .jar is unpackable? I assume you did use the jar utility, right?

You can also try to upload the final file in the .zip format. The runnable file inside the final file has to be .jar (runme.jar, to be more specific), but the file that contains all the deliverables can be .zip too.
You can check that on the page where you upload the assignment.

So, just to make sure again,

if the following command -
"jar xf submissionfilename.jar"
extracts files correctly,
then the file isn't corrupted, right?
