Hi,
so, why using BMP if you can do the same into session beans ?
is your question ...
- with BMP you write the data access code, but you let the
container manage the data synchronisation, transactions, i.e.
when to load/store the data ...
- entity beans are shared between several clients, while a session
bean is dedicated to one client.
Regards,
François
