Taking part 1 one was piece of cake after taking OCEJPA,OCEEJB and OCEWSD. There were many questions that were already covered by these exams. So It took me 2 weeks and a half approximately 9 hours per day study which resulted in 84%.
In the process I read the Oracle Guide which I find to be very very very boring.
UML distilled which is a good book for UML.
And
Java EE design
patterns rethinked which I find to be excellent book.
What I did not covered enough and what probably costed me points is the different attacking strategies like Denial of cervis, cross scripting attacks and so on...
Also there was one category of questions on the exam that in my opinion is very confusing. When you have like several answers and you all of them are partially correct and you need to choose the most correct.
Moving forward to the assignment.
