I just got my copy of Head First: JSP & Servlets 2nd Ed. today. I'm so excited.
I do have a question. Do I need to update my SCJP 1.2 to a later edition before I can take the SCWCD? I'm slightly confused because I've read where as long as you hold a SCJP 1.2 or better your good to go. I've also read that you have to have an SCJP 1.2 that does not expire. I guess some of the earlier SCJP's expired and required a renewal. I think I took mine back in 1999.
