Hi Neelu,
I would recommend that you look at the JavaRanch
SCEA Links and
SCEA FAQ pages. The
SCEA links page has a lot of links to topics of interest on the web, mock exams, and books.
In particular, most candidates here seem to use one or both of:
Sun Certified Enterprise Architect for J2EE Technology by Mark Cade, Simon RobertsSun Certified Enterprise Architect for J2EE Study Guide (Exam 310-051) by Paul R. Allen, Joseph J. Bambara[/url] I only used the first one (writen by the exam's authors), and found it a good revision book for my existing knowledge. I have my doubts as to whether someone reading it would actually learn enough to consider themselves an architct though. Be warned - it does not cover 'legacy connectivity' at all.
Regards, Andrew
