Yes, to both. The Object type pk will turn on the unknown pk code, and
JBoss specific metadata will be used to configure the system.

Both. Actually I think there will be three supported types.
- Get pk value from some generator MBean before the insert
- Get the pk value after the insert using JDBC 3.0
- Get the pk value after the insert using a special DB query
