Is TransactionSynchronizationRegistry used?

[David Jencks <da...@yahoo.com>]

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

thanks

Interesting.  I knew about the "backdoor" approach for accessing the various
Transaction Managers, but I thought OpenJPA would have had the new
TransactionSynchronizationRegistry as well.  I will open a JIRA report to
address this issue.

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.
