Thanks.
Is this saying that if I don't make the dependant object an EB (with all the
development and runtime overhead), I am left with BMP ?
Cheers

My understanding is you are trying to model an entity bean where dependent
objects are involved.
Checkout section 9.1.2(Granularity of Entity beans), that might help

Subject: EJB design when one object has a second within
Has anyone a recommendation for modelling EJBs when one object (say
customer) has another object (say address) which only they can own
[customer/address is therefore not a perfect example].
Ideally object #1 would have a reference to object #2. But I think I am
right in saying that CMP could then not be used to farm object #2's data and
store within the database row - is this correct ?
An obvious way I can see around this is to dispense with object #2 and have
the data stored as attributes in object #1 but this does not seem very
OO-ish.
Alternatively, object #2 could be upgraded to an EJB, I could determine a
simple type PK and store this within object #1. But what if the primary key
is more complex (address would probably have building designation and postal
code) ?
TIA
