Just finished the Part III essay exam this evening. Hope to get the result 4 weeks after.


Btw, is there any summary (either offically or unoffically) about the distribution of SCEAs in the world just like CISSP ?


SCJP, SCWCD, SCEA

Good luck!
I was just asking myself how many SCEA are in the world!
What a coincidence!

Hello Alex,
did you use EntityBean in your part 2? I am thinking of using some ORM such as hibernate instead? what's your thought? is EntityBean required?
Good luck on your test.
Thanks.

Hi Brian,

Yes, I followed the classic J2EE framework where entity beans (CMP) are used to represent the domain objects and session beans are as facades in the EJB tier. Moreover, I mentioned in the assignement that entity beans were applied for mapping single entity only. For those scenarios where large quantities data with complex relationships are retrieved, I used the Fast Lane Reader pattern (i.e. DAO component) because of the heavy-weight lifecycle management imposed in EJB spec.

There is no right or wrong on using EJB or Hibernate. Your assignment will be marked base on how you jusify your solution. For example, performance, scalability, mantainibility or even productivity (time to market etc)..
 
It is sorta covered in the JavaRanch Style Guide.
