Actually certification last for only 2 years
what is means can be complicated ...
In my case:
I certified almost two years ago for SCJP 1.4
I have:
1. To Recertify AGAIN in 1.4 (stupid, stupid, stupid !), as there seems
there won't be a SCJP 5 in the near future ...
2. To certify in SCWCD 1.4 (on five days 1.3 certification disappears)
(Only 1 book available , the order is in amazon, Kathy
before my certification 'expires'.
(No, not interested in the other Sun Java certifications, right now ...)
I have found the Austrlian FAQ informative:
http://suned.sun.com/AU/certification/faq/ Search for 'expiration'
Hope this helps ...
