Hi Dilini, What is the Acknowledgement Type you are hoping to use here? Or is it configurable?
Acknowledgment type changes the way JMS messages are acked. Once acked, message is getting removed from the queue. i.e if you use AUTO_ACK message will be acked no matter processing failed or not. If you need to preserve message (and maybe re-try), you should consider other acknowledgement types. http://wso2.com/library/articles/2013/01/jms-message-delivery-reliability-acknowledgement-patterns/ Thanks On Wed, Dec 2, 2015 at 11:41 AM, Dilini Mihindra <[email protected]> wrote: > Hi, > > WSO2 BPS already contains a RESTInvokerTask to send a message from a BPMN > process instance to a REST service.
