I uploaded the jar (size<400k) file for SCEA part 2 assignment a couple of months ago, I got an error. I immediately sent the email to email@example.com; they told me jar is successfully received.
But when I finished part3, I was graded "F", in the comment field, the accessor asked me to re-upload the jar file since the jar file is corrupted. Therefore I tried to contact firstname.lastname@example.org to grant me re-upload permission.
No response. I have been contacting them for a few weeks.
The upload process has been discontinued. The new process involves sending the jar file as an email attachment. Please check the Oracle site for the email address and other instructions including email subject line etc.
