After a wait of around three weeks, I finally saw a Pass post in the Sun site.
Test: Sun Certified Enterprise Architect for J2EE 5, Part 3 (310-062)
Date Taken: 2009-05-17 23:10:56.390
Registration Number: r93syd511f
I prepared from several books and the ePractizeLabs software. I also had real-time experience working on medium-to-large scale JEE applications as a developer, team lead, designer and architect spread through almost seven years.
For the assignment, it was mainly problem solving and experience. I do not think there is any book available in the market. Maybe one can write! However the ePracticeLabs software provides some pointers but then the real problem is much more complex.
