I gather that scjp is must for appearing for scwcd.
I am about to buy a voucher for SCWCD, i was wandering how sun/prometeric will make sure that i have already cleared scjp exam. I don't have any records with me, but i do have the scjp certificate.
You must have been assigned a unique Prometric candidate ID when you took your SCJP last time. That ID is used to track your progress. You can see your details on Cert Manager Site.
unfortunately i dont remember my candidate id and its not printed on certificate. I will check the link you have provided for cert manager, right now it seems to be down till march 3.
