Re: Does OJB supports Geronimo?

hello armin,

sorry for the late reply and thank you for your help!
I  had to skip the managed transactions and use the normal
PersistenceBrokerImpl.
However I have tried your suggestion and failed
got a: org.apache.ojb.broker.PBFactoryException: Can't instantiate
TransactionManager of managed environment
with not further details.
