Dear Krishnan,
Sorry to bother you again. I have a design question. In CMP 2.0, CMR fields linking
to entity beans cause those entity beans to be better cached, right? In that context,
I was thinking using the superclass value object B in your example goes against the
whole acceptable fine-grained design for entity bean. Why not make the entity a you
are trying to "bulk set" into another entity bean, and make it a CMR field in Bean A?
This shouldn't be too much of a performance overhead if the contatiner caches CMR
entities in memory. Here is a code example to better understand...
---------------------------
coarse grained model :
Value Object B
|
\/
entity A extends B
---------------------------
fine grained model:
Entity A has public abstract EntityB getB()
Entity B has the value object variables
---------------------------
What do you think?
Warmest Regards,
Eric Dunn
