Hi all,
I have few questions about Part 2. I have problem with how many and which objects/components to list in the diagrams etc. I just don't want to overdo it but on the other side I want to provide enough information for the 'marker' to understand my design. I know that a lot of the questions were probably answered before. I would like to ask those of you that already passed Part 2 following questions:
1) How many classes did you include in the class diagram and how many class diagrams did you provide?
2) How many components did you list in the component diagram?
3) Did you have to split large sequence diagrams into two?
From what I've heard it is enough if class diagram contains just EJBs(if there are any), Value Objects, DAOs, ServiceLocator etc. Do I have to list also HTMLAction, FrontController and other WAF classes? I still want to include WAF in the sequence diagrams.
If somebody considers above questions going too far, I apologize. Thanks for all inputs.
Tomas

Hi Tomas,
It appears to be your first post in the forum. Welcome aboard!
If you search the forum for "passed" you will find a lot of information from the folks who have already passed the exam on questions (1) and (2). From what I have seen, people have been successful with both of these approaches. So, there is more than one right approach for depicting your design.

>>> 3) Did you have to split large sequence diagrams into two?
Some people split large sequence diagrams into more than one smaller diagrams. You could alternatively choose to keep it simple and attach UML notes to the diagram to explain what your diagram doesn't communicate explicitly.
>>>From what I've heard it is enough if class diagram contains just EJBs(if there are any), Value Objects, DAOs, ServiceLocator etc.
Sun hints in the exam instructions that you need to show the J2EE components/patterns in the Componennt Diagrams and not the Class Diagrams. But then there are many people who have succeeded with high scores submitting overloaded Class diagrams.
>> Do I have to list also HTMLAction, FrontController and other WAF classes? I still want to include WAF in the sequence diagrams.
Just show it where it makes the most sense to you and provide the relevant documentation.
>>> If somebody considers above questions going too far,
I find your questions well within limits.
Regards
Sridhar
