This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
I saw my results posted and was shocked to see that I have failed.
I re-checked the assignment that I had posted and am at a loss to understand where I had gone wrong.
I had broken up the classes into logical packages and shown the relations between them.
For EJBs I had all the home-interface, remote-interface, primary-key classes for each component depicted in the class diagram.
The component diagrams were broken up into showing the relation of components in different tiers.
The only things that I had not depicted was the rich-client gui classes/components. But I think it is only server side components that need to be depicted and I have received 12/12 in sequence diagram where I have drawn the diagrams corresponding to web-based elements only.
What did I do wrong?
I had also used Visio tool to make the diagrams and when I converted it to HTML I realized that it uses activex controls and hence needs to be opened in IE to fully view the diagrams and use zoom-in/zoom-out functionality (Necessary for large diagrams).
I had an extra html file giving browser-instructions.
So my suggestion is to not use Visio for the assignment and use some other tool like StarUML. I havent tried StarUML.
I had not shown the standard methods of the Home interface class from which every EJB home interface class was deriving but I had used the fully qualified name of the HomeInterface class. Since the assignment statement says clearly we dont have to show all the methods or member variables, I felt the names of these standard classes from the javax package should represent that and would help in not making the diagrams cumbersome.
I think I could have been penalized for that but still that is not a sufficient reason to flunk me.
As for the component diagrams I dont know what the evaluator was expecting.
Any of you people have links to explanation in component diagrams or how to represent JSPs in UML?
I think it is totally unfair on Sun's part for not giving more details of the evaluator's reasons for failing a candidate.
Atleast they should provide details for candidates who fail so that they realize their mistakes.
I feel bitter that I paid $700 and spent the time and effort to flunk the assignment and dont know why I flunked.

I am really sorry to hear this!! Please dont give up.
Can you resubmit your assignment for SCEA2 ?

Thanks for your words of support and concern.
I cannot resubmit since it is an old version of the SCEA exam which has expired.
I put in a lot of effort on the sequence diagrams. Looking at the points allocated I should have focused more on the class-diagram and the component-diagram. And, I shouldnt have left out any detail in those diagrams.
The choice of tool was the biggest mistake I guess and it was too late before I realized the problems with it.
I have found very little material on component diagrams and representation of J2EE elements in this diagram. I shouldv worked on this more I guess.
In my work experience I havent made too many component diagrams and Iv found it very useful in combination with the deployment diagrams only.
Anyways I am posting this so that you guys can learn from my mistakes.
