Hi Willy
i think you are right. Its first better to be certified with SCWCD, SCBCD and SCWSD before going on for SCEA.
BTW what material are you using to study for SCWCD? I am using only Head First Servlets and JSP. I feel this is enough to get a good score on the exam
I tried reading Manning SCWCD but it is too dry! So dropped it
