Listener Exception handling
Requirement: JMS listener need to process the each message from the JMS Queue and create one work object
Design:In the listener activity, we are calling work object flow by passing the message information. In that flow we are keeping the one temporary assignment after start shape and queuing this assignment to Agent, this will reduce processing time of the listener and it will resume to work on the next message in the Queue.
In this entire process if listener fails to create work object by any reason, how can we handle? What about the message, will it be re-queued again?
Is there any chance the messages in the queue is going to deleted, do we have any recovery?
If i enabled listener in all node, is there any chance that the same message is going to processed again?
Please share your ideas or correct if there is any correction

Thanks Sudhakar for your reply! Since we have problem with agent queues, we are planning to change design as follows..
JMS listener will create WO, the work object flow have one stub assignment after start shape, after this assignment we are planning to incorporate business logic. So listener won`t spend more time on the processing logic
One agent will monitor this table and process the rest of the business logic
if listener picks message and fails to create WO due to some server issue. Will it be re-queued?
