It took me around 6 months to finish and submit the assignment - mid July. I was not able to give proper time for this due to work and family. I took exam the next day. I got result back in 4 weeks. The result was posted in
http://www.CertManager.net/sun_assignment. I went over the requirements many times. Every time I re-read the requirements, I seemed to find problems in my design and changed it several times. Posts in JavaRanch helped to find answers to many of my questions and doubts.
I had 1 class diagram, 1 component diagram and 4 sequence diagram. Clas diagram did include session beans. Was careful on navigation, multiplcity, streotypes and other UML rules. Added several classes to meet the business requirements. Showed how I used
patterns in Component Diagram. 1 Sequence Diagram for each use-case.
