I used the book "Sun Certified Enterprise Architecture for J2EE Technology Study Guide" by Mark Cade and also references from this site http://www.bm-one.com/Se/scea1.html for areas that Mark Cade book didn't covered. I used this site http://www.moelholm.com/data/mocks/mocks_scea.xml also for mock exam to look for areas that I find myself weak. I went through SCWCD 1.4 and SCBCD 1.3 which helps me a lot to have a good score for this exam. I am an avid reader of javaranch ever since I prepared for SCJP 1.4 which served as my guide in my preparation for the exams I finished already.
Thanks you for all you who have taken an exam and have given your testimonies here in this website unselfishly. You have served as an inspiration to people like me.
