I read some article stating that relationships in component diagram should be established using suitable interfaces between components.
I am kind of confused by this...Does that mean we need to show interfaces for all components or for EJB components only (the lollipop notation)? I was looking into Cade's book and he hasn't shown any interface except the circular one (and that too for content management only).

Can somebody who has already cleared this exam can throw some light on this?...I am unable to find any good component diagram on the web.

Any help would be highly appreciated.

Hi,

There are numerous ways of showing interface notations on a component diagram but the most commonly used approach is the lollipop. Please note that UML 2.0 also includes another approach that shows the adapter and interface connectors but once again this is an inclusion not a replacement.

Unfortunately, the level of detail within the required deliverables is not defined by Sun and this is one of my main issues with the instructions. UML is a powerful notation tool that can be used at various levels of abstraction. With very little knowledge from Sun, with the exception of a "architecture and design..." (yeh, that means hell of a lot in an industry that is still trying to define what software architecture actually is and design - high level detail logical physical - what?), the students are suppose to simply plug into the great "Orb" and suddenly know the level of the detail required by the assessors.

My personal opinion is that Cade's book does not provide adequate examples of the level of detail expected. Are interfaces required, if so, as you pointed out, why does Cade's book only use them for one component?

So many questions - Sun...Sun..anyone there?

This certifications is so different from the SCJD. In that certification, also an assignment, we knew exactly what was expected and the level required to pass. It still required further studying but at least you knew what the assessors expected.

Regards,

:roll:
