For amar kasar :-
I managed to do it in 15 days because most of the thing I managed either from my previous reading Or from experiance(4.5 yrs). For example I did not read "Design Pattern" at all- Similarly no requirement for reading Filter chapter also. Most of the DD tags and Session were know to me from experiance . But I was not so familiar with custom tag. So, whereever gap was there , it was filled up by GREAT HFSJ book. I didnot expect I will struggle in "Servlet Tech Model" or "JSP standard action". Actually I should have read those area more carefully.
For the exam taker: -
Be sure you know the clear difference among 1) include file= .... 2) jsp:include and 3) c:import. I got around 4 questions in this area which requires clear understanding of these 3 elements. Try to write some code in this area.
For Design Pattern, you may read Core J2EE pattern if you want to get more than whatever is there in HFSJ last chapter .
Read each and every "BANG" and "Dumb question" of HFSJ-- these are really important for the exam. So, dont miss it!!
Next I will try to give SCDJWS. But alas! No Head First is there! So, let me see how it can be managed.
SCJP, SCBCD, SCWCD, SCEA
