Now my time to give feedback to community, I passed SCEA 2 and 3 with 90%.
I preapred around 12 pages documentation with sections as requirements summary, assumptions, architecture and design choices.
One class diagram only few attributes shown for some of classess
One component diagram with detailed J2ee components and design patterns hightlighted
Seven Sequence diagram , 4 for each usecases, 2 for login and 1 for delegate and facade interaction
I spent 2 weeks on part 2 assignment. I took off from work. I do not have any big direct j2ee development and implementation experience. I have doen few small j2ee project but old java guy.
Part 3 was very easy, asking how you have handled this , that in your architecture.
Hopefully this is helpful to users.
