Hi all brainies,

Hope you all well,
Sorry for been asking stupid question, I been struggle to draw the JSF Framework in component diagram,
Some questions :

Component - There are 6 stages in the JSF Framwork, do we need to breakdown the details of which life cycle belong to what design pattern?
Class diagram - do we need to draw the presentation layer in class diagram?
Sequence diagram – I am reusing the entity beans as a datamodel as well as using them as a backing bean in presentation layer, can I defined the entity component ‘s design pattern as composite entity / transfer object / context object?

again, much appreciate, i am stucked for weeks.

thanks

I don't think that is part of the scope of the SCEA exam. I would, and did, not.

>>do we need to draw the presentation layer in class diagram?

My opinion is that your class diagram documents your domain model. I don't see any reason why a presentation layer artifact should be referenced in a domain model.

>>composite entity / transfer object / context object

If you think the one single component plays all of these roles, and you believe that all of these roles are pertinent to a properly designed JEE5 application, then sure. I'd be hesitant to use the term 'transfer object' in a JEE5 project. Do you think 'transfer objects' still have a place in a JEE5 application?

Here's actually a good discussion on design patterns. You might get a good idea of what I mean about the 'transfer object' pattern.

I am doubtful about working in UML in part I of the exam. Does UML included in exam objectives?
