AW: Problems with PersistenceBrokerSyncImpl
Hi Armin
Should it not be hidden from the user of ojb. With this solution
A user of ojb has to implement two different db layers: one for managed
Environment and one for not managed environment.
What happens if I inherit from your PersistenceBrokerFactorySyncImpl class
And overwrite the begin, abort and commit Transaction function and implement
This functions as empty function?
Regards
Matthias

In managed environments the tx handling/demarcation is done by JTA, so it's
no longer allowed to use the PB-tx demarcation.

If you use websphere as simple servlet engine without distributed tx,
there is no need to use the JTA integration supported by PBFSyncImpl. If
you use JTA it's mandatory to use PBFSyncImpl and JTA-tx demarcation.

more elegant is to:
- extend PersistenceBrokerFactorySyncImpl
- extend inner class PersistenceBrokerSyncImpl and override beginTx, ...
methods to noop
- override PersistenceBrokerFactorySyncImpl.wrapBrokerWithPoolingHandle
and return the extended PersistenceBrokerSyncImpl class

This could solve your problem, but this class is really complex. You
have to extend inner class PBSyncHandle an override the methods.
I will have a look at it, maybe I can integrate such a solution in the
upcoming bug-fix release.
