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.
Could you please share your cert path experience JPA, EJB, WS?
What was the order of the exams?
Do you think it's important or necessary to take WSD exam after JPA, EJB or it can be skipped if I plan to take in future Architect exam?
What required Oracle study coarse for getting Architect cert have you decided to take?
I think JPA comes first as it requires least dependencies from the JEE. I have never took the OCEWCD but if I think that it comes second place, or you take OCEEJB I would place both of them on second place. Does@t really matter which one you take first. I personally found OCEWSD most demanding, also had one of my worst certification exams fails ever on it. Probably if I had previously taken the OCEWCD this could have been avoided. But either way.
OCEJPA->OCEEJB->OCEWCD->OCEJSF or OCEWSD thats how i see it.
