Out of the box the isolation-level setting is only used by the ODMG-api 
which use pessimistic locking by default.
http://db.apache.org/ojb/docu/guides/lockmanager.html#Pessimistic-Locking
The PB-api doesn't use pessimistic locking, thus it will ignore these 
settings.

The database transaction levels are completely independent from the 
isolation-level setting in OJB. So you can use different database 
transaction levels (e.g. as property in the dbalias attribute in the 
jdbc-connection-descriptor)
