First of all, I give my great appreciate for your guys and this forum. Though I didn't give much dissution here, yet I got lots of helpful information.
I spent around two weeks in clearing this exam. I got errors on one question in isSecure(), and two questions in thread-safe questions.
the materials I used include:
More Servlet and JSP;
SCWCD Study Kit;(with JWebPlus+)
Servlet and JSP APIs;
Servlet and JSP specifications;
I would recommend Study Kit with JWebPlus, plus APIs and specifications for this exam. More Servlet and JSP book is good, but it is not for the exam study.
and I would recommend to remember all of the required web.xml elements and TLD elements so that some very sample questions will not get confuse.
Get a clear APIs study is good for this exam. and specification will help you understand some more deep content.
