Thanks, I assumed I would need to make these calls to an RA. But let's suppose I do that. Will that help my transaction issue? Will the RA be treated as a resource manager (for inclusion in XA)? In other words, will the following be true if I write and deploy an RA that makes the calls to WorkManager | 1) A CMT transaction TX1 is created in the EJB via hibernate call. | 2) the ejb uses the Resource Adapter to schedule work | 3) A new transaction is created TX2 by the WorkManager? | 4) TX2 will now participate in the XA transaction? | | | Again a note: cmt transactions are used. I never 'have' programmatic access to TX1. I'm using the MySQL XA driver and have correctly setup the xa datasource.
