Subject [jira] Commented: (OPENJPA-61) Missing usage of TransactionSynchronizationRegistry
Date Tue, 24 Apr 2007 19:58:15 GMT

    [ https://issues.apache.org/jira/browse/OPENJPA-61?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12491423
] 

Marc Prud'hommeaux commented on OPENJPA-61:
-------------------------------------------

Note that you should make sure that you are really using the new RegistryManagedRuntime, since
if any exceptions occur when loading that class, they will be silently consumed and it will
fall back to using the old internal APIs for accessing the TransactionManager.

You should be able to force it to use the new class by specifying "openjpa.ManagedRuntime"
to be "org.apache.openjpa.ee.RegistryManagedRuntime".

> 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...

> 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.
