So, does that mean there is no solution for consuming multiple JMS messages in a single transaction? Such that transactionality is correctly respected, ie if something goes wrong with the Nth such message the whole batch is rolled back.
Ideally without the need to use a transactional aggregator to it into a persistent store. I don't have much interest in configuring a local storage DB, just want to process the batch of messages and then move on (or roll back). — Sent from Mailbox for iPhone On Fri, Jan 24, 2014 at 3:38 PM, sully6768 [via Camel] <ml-node+s465427n5746450...@n5.nabble.com> wrote: > Hi RK, > SJMS batch transaction consumes messages individually and does not use or > produce a List.
