Thank you Ron!
>From the FAQ:
Q: I don't like OQL, can I use the PersistenceBroker Queries within ODMG?
A:
Yes you can! The ODMG implementation relies on PB Queries internally!
Several users (including myself) are doing this.
If you have a look at the execute() method in
org.apache.ojb.odmg.oql.OqlQueryImpl you will see how OJB Query objects can
be used withing ODMG transactions. The most important thing is to lock all
objects returned by a query to the current transaction.

have rebelled they cannot become conscious"

to do exactly what you're talking about. However, I'm not sure how you'd go
about working with the PB and ODMG apis within the same transaction.
