I am glad to say that I have cleared SCWCD. I must say that the syllabus for this exam is really vast. I have learnt a lot of concepts during my preparation for SCWCD. I found that there were lot of questions atleast 5 on EL, JSTL, J2EEpatterns and custom tags.
HFSJ explains all the concepts very clearly. I also read Mannings edition for 080 exam. Both these books are really good. I went through the specs for servlet and jstl. Reading through the specs explains a lot more details for every tag in jstl. I think one should read the specs for jstl. I took this exam preparation time as an opportunity to learn all these concepts as much as possible.
I am glad to say that I scored 92% and that it is all over! My next aim is to learn Struts and log4j logging in a formal way reading through books and learn lot on these concepts before I start preparing for SCWBD.
