Subject Re: Transactional Route with JTA
Date Fri, 30 Oct 2015 14:37:56 GMT
Hi Christian,

You need to plug in the JTA TransactionManager into the JMS consumer, so
that the transaction is opened as part of the consumption.

Otherwise, the transaction starts after the route kicks off and therefore
doesn't cover the JMS consumption itself.

Maybe this resource helps:
