SUN responded with the following:
The SCEA v1 was retired on February 28, 2008 with the release of the new SCEA 5. You have until December 31, 2008 to complete all parts of this certification.
If you have not purchased the SCEA v1 Part 3 essay exam (310-061), you may still purchase this exam through the Sun Training Registrar in your country. The exams are not available for purchase online.
Please use the link below to obtain the contact information for the Sun Registrar in your country: http://www.sun.com/training/world_training.html
The retired SCEA v1 did not have a time limit for completion, so you do not have to complete the assignment within one year of purchase.
