Here's a radical voice.
I threw away the disgusting O/R mess that Entity beans continue to
perpetrate and just used a persistent OODB - PSEPro/ObjectStore with
transactions wrapped inside session beans.
Unfortunately there is no native support for OODBs under J2EE, and never
will be, because Sun needs Oracle revenues <grin />, and because most
e-business applications don't need arbitrary reference graphs. If you want
to distribute OODB transactions you'll have to wait for the J2EE Connector
and probably write your own glue.
This doesn't really answer your question, but if anyone is interested in
how to implement ODI-style transactional persistence within a session
bean, I might write up a detailed howto for orionsupport. Sadly, it turns
session beans into glorified RMI servers.
