I have done with SCWCD 95%. HFSJ and J Web Plus mock exam and ofcourse javaranch helped me lot during this. I have studied both HFSJ and deshmukh.Both helped a lot to understand in depth. But, I think HFSJ and J web mock exams are enough. I also gone thru the servlet spec but not JSP spec.
First I would like to congratulate you for your big success. I am also preparing for the SCWCD Exam. Can you please send me name of the books you have referred? also please send me any pdf book or material prepared by you to my email address email@example.com
