[rules-users] JTA question

[Allen Day]

Kris,

Thanks again for your help with this!

If you want to help, you could provide native support for the TransactionSynchronizationRegistry as an alternative to
TransactionManager.  We created a new issue for that here:

https://jira.jboss.org/jira/browse/JBRULES-2322

Thanks,
  Allen

Quoting Allen Day <DayAK at ldschurch.org>:

No, this class handles the transaction management.

Sure, we use a provider strategy for getting the actual implementation.
 So you can use JPAKnowledgeService.setJPAKnowledgeServiceProvider to
configure another provider. If you look at
JPAKnowledgeServiceProviderImpl, it simply uses a property to specify
the command service, so your own provider impl. should change that to
use your custom implementation:
  props.setProperty( "drools.commandService", 
    "org.drools.persistence.session.SingleSessionCommandService" );

Let us know how it goes, or if there is anything we could improve in our
implementation to make this easier for you.

Kris
