Hi, I've never used OJB in managed environment, but looking at the PersistenBrokerFactorySyncImpl (http://cvs.apache.org/viewcvs.cgi/db-ojb/src/java/org/apache/ojb/broker/cor e/PersistenceBrokerFactorySyncImpl.java?view=markup) specifically, the PersistenceBrokerSyncImpl inner class, it certainly seems to implement to the Synchronsation and pass on the calls to the delegating PB - which would intern invoke the listeners.
However, the tricky bit would be where to add the listeners - as you'd have to subclass the PersistenceBrokerFactorySyncImpl broker factory. Armin seems to be the man to do with using PB in a managed environment; I'll have to leave you in his hands for where to add the listeners.

I just found Listener for Transaction stuff in the API. Any suggestions?
