I am very sorry to come back to the same topic after such a long time, but we are super bussy to get our thing up and running.
we are using the Persistent Broker API in an managed enviroment as jboss or OC4J (oracle application server). using the ojb.org.apache.ojb.broker.accesslayer.ConnectionFactoryManagedImpl from
OJB with jboss I see the following log:
-------------------------------------------------------------------------------
[ejb.ojb.org.apache.ojb.broker.accesslayer.ConnectionManagerImpl] (Thread-10) Rollback was called, do rollback on current connection [EMAIL PROTECTED]
[ejb.ojb.org.apache.ojb.broker.accesslayer.ConnectionManagerImpl] (Thread-10) Rollback on the underlying connection failed
java.sql.SQLException: You cannot rollback during a managed transaction!

-------------------------------------------------------------------------------
if I use an implentation which produces connections with a NOOP-rollback method, than I see only:
-------------------------------------------------------------------------------
[ejb.ojb.org.apache.ojb.broker.accesslayer.ConnectionManagerImpl] (Thread-11) Rollback was called, do rollback on current connection [EMAIL PROTECTED]
14:00:20,312 INFO [STDOUT] ** we ignore rollback
-------------------------------------------------------------------------------
when I understand the JDO spec correct, than the transaction borders is done by the embedding enviroment only.
so altogether our own implementation works fine on jboss and on OC4J with our connection factory.
FYI: OJB really helped us a lot to have an application which deploys easiely on serveral application servers !!
hope you find the time for checking it.
best wishes Kristian
