Hi all,
I took the SCWCD exam last week and passed scoring 85%. I am happy with my score.
I used HFS, the specs and a few mock exams - javaranch, j2eecertificate, JWebPlus trial for my preparation. I scored 71% on the HFS mock exam. Some of these mocks are for the J2EE 1.3, so pay attention to what is relevant for 1.4.
Here are a few suggestions for future exam takers:
Know all the DD elements very well - including env-entry tags and EJB related tags.
Know EL very well - You need this to answer EL questions and also to answers questions on custom tags. You really need to know this!
Know the attributes for JSTL tags - what is valid, required or optional.
JSP and EL implicit object and what class/interface type they are.
Know the API for some of the important classes - the classes and some important methods are given in HFS chapters.
Questions on design patterns were pretty straight forward- scored 100% on this section.
Few things you need to know, but covered lightly on HFS are - dynamic attributes, RequestDispatcher include method.
Hope this info is useful.
