After a long hiatus, I decided to take up this certification and prepared for a month approx. The exam (taken today), given the preparation outlined below, was fairly straight-forward. Just was surprised by a couple of picky API questions and a couple of ambiguous ones (per me).
My study recipe:
Read HFSJ (first edition) twice
Read Manning's SCWCD Exam Study Kit (second edition) once - great for some of the finer points wrt tag file directives, tag dynamic attributes
Cross-linked w/ the J2EE, JSTL, J2SE APIs whenever in doubt
HFSJ first edition mock exam one day before the test (scored 78% on the mock).
