Folks,

Sorry, attached mail should have read "not every (reasonably dynamic)
persistent entity should be modelled by an entity EJB"

i.e. drop the "bean".

When do persistent database entities warrant an entity EJB?


Thanks - Adam

Subject: Architecture: When to use Entity Beans to model persistent
objects?


Folks,


I am interested in the frequently voiced opinion that not every (reasonably
dynamic) persistent entity bean should be modelled by an entity EJB.
I am designing a J2EE server consisting of client facing session beans,
action and modelfactory (valueobject factory) classes interfacing onto
persistent entity EJB's.

Are there any rules of thumb as to when one should use an entity EJB to
model a persistent object? Any opinions?


Thanks in advance
