I received my assignment results about 4 weeks after I did the essay. I am pleased to say that I am now a certified Java Architect with surprisingly high results of 151 points out of 160. I say surprising because I had doubts about my deployment diagram and I suspect this is where I lost 9 points. Not that it really matters.
Thank you for all your postings. This forum & the kind people that answered my questions really helped me.
Good luck to you all!
