If not, why not?
Any thoughts appreciated,

Hi Harbo & Parag,
Personally, I wouldn't use composite entities at all now that EJB 2.0 is available. Whether I went for BMP or CMP, I would use 'local' for all entity beans. I would access these through session beans acting as facades. I would pass data back to the client (web tier) using 'data transfer objects'.
For the exam, I personally don't think you need to mention about BMP or CMP, as it won't make a difference to the diagrams. Can anyone who's passed the exam comment on this?
