I'm preparing to take the SCWCD exam, and being new to servlets and JSP I have some questions. All of the study material I currently have discusses the Servlet API 2.3 and JSP 1.2, yet J2EE 1.4 includes later versions of both JSP and servlets. Is anything included in those later versions going to be important for the exam?
Also, I know the 1.4 exam requires a lot more in the area of design patterns than the 1.3 exam does. Are there any other major differences? I currently have the Deshmukh-Malavia book and have the Head First book on preorder. Is there anything in the former book I need to be careful about because it is based on 1.3 objectives?
