Description

A discussion on the dev mailing list indicates that OpenJPA currently does not utilize the TransactionSynchronizationRegistry. Although OpenJPA does provide other means of finding and accessing the various TransactionManagers, we should update OpenJPA to use the standard interfaces. Following are the two notes on this subject...

I'm trying to get openjpa running in geronimo and wonder how openjpa
locates the TransactionSynchronizationRegistry. Grep'ing for
TransactionSynchronizationRegistry I don't see it used anywhere in
the code base. What am I missing?

thanks

David-

We don't use TransactionSynchronizationRegistry (not yet, at least).
Instead, we manually locate the TransactionManager via appserver-
specific heuristics defined in openjpa-kernel/src/main/java/org/
apache/openjpa/ee/AutomaticManagedRuntime.java

If the Geronimo TransactionManager is accessible from JNDI or some
method invocation, you can just add it into AutomaticManagedRuntime
as a default (you can test it out by specifying the
"openjpa.ManagedRuntime" property to "jndi
(TransactionManagerName=java:/GeronimoJNDINameForTransactionManager)".

We may add support for integration via
TransactionSynchronizationRegistry in the future, but the fact that
it doesn't provide support for accessing the current Transaction
would mean that we would need to rework some OpenJPA internals.
