I just began studying for the exam. I bought the Head First Servlets and JSP book. My question is this. The exam is on web technology in J2EE 1.4. The current level of the spces is servlets 2.5 and JSP 2.1. Those aren't the levels covered by the book. Should I expect exam questions based on these later specifications? Looking at the exam page itself, SCWCD Examination I can't tell which version of the specs I will need to know. Can someone please tell me if the book I've got is sufficient, or do I need to read more recent specs as well? Thanks.
