I cleared the SCJP 1.5 yesterday and tryed to log on http://www.certmanager.net/sun with the information given on my exam report and get this messsage : We could not find a user meeting the specified criteria. Please review the criteria and try again.
It may take a few days for Sun's database to be updated with your test record. Since this is presumably your first Sun certification exam, your account will be created only when they add the exam record. Just be patient and check again in a few days (or next week).
