Thank you all.
This is what i have used for the preparation.
SCEA for
J2EE Technology Study Guide - Mark Cade & Simon Roberts
JAVA EE Tutorial
Core Security
Patterns Core Design Patterns
Design Patterns Explained
Alan Shalloway & James Trott (This book is a good start to understand core patterns then one can switch to Gang of Four)
Design Patterns: Elements of Reusable Object-Oriented Software - G4
http://java.boot.by/scea5-guide/ (First two chapters)
http://java.sun.com/javaee/ (General browsing of FAQ, Technology section gives a good idea of overall J2EE & RESTFUL webservices)
There is one book which is not directly related to the exam objectives but can give a very good idea about IT architecture,and i will strongly recommend it though its not one of those very exciting books.
IT Architectures and Middleware - Chris Britton
The questions asked in the exam were totally covered in the above reading.
One cautious note - There are several links posted in the forum and on internet, most of them are not up to date for SCEA 5 and one can save time by sticking to the books posted here or by the Cameron.
Two month of preparation is what i required for myself, first month being lighter and with second month being intense and studying for atleast 3-4 hrs a day.
I have 9 yrs of exp with some architectural.
