SCWCD Beta exam is based on the J2EE 1.4 SDK. The major differences between this (1.4) and the previous SCWCD exam are, additions of new things viz. EL, JSTL, Tag files[SimpleTag] etc. Yes, this exam will be available in production in about 2-3 months from now for a fee and will only contain ~60 questions (right now ~160). Book: For the earlier SCWCD, I used Professional SCWCD from Wrox publication. Very to the point book. Since I haven't studied the Deshmukh book, I can't say anything about it. You should read the specifications (it's little harder to read specs though), for SCWCD 1.4 along with other resources suggested by fellow ranchers.
