I have cleared the exam on 10/31/2007 but I haven't still received the certification kit.I'm registred on sun certificated database and i'm waiting it since 11/08/2007 because the kit has been mailed in this day. When did you receive the certification kit?
Don't worry, the delay is normal. The kit is always indicated as "mailed" about a week after you take the exam, but you may not actually receive it for another few more weeks. If you still haven't gotten it after a month, you can contact Prometric as indicated in Sun's certification FAQ:
"If you still have not received your certificate after the one month waiting period and your address is correct in the CertManager database, please send an email message to firstname.lastname@example.org. Please include your Prometric Student ID number in your message."
