<div dir="ltr">Here, after catching the exception I want send it back to the producer, so that my client will know what kind of error occurred at backend system. As mentioned above if exception occurred inside the handleMessag method message will not deleted from the queue, that is fine and to printing that error message by registering ErrorHandler with the listener container. But, I want to send that exception to the producer, can you please tell me how can we send it back to producer?<div>

<div dir="ltr">However, if you use ackMode=AUTO, the container will take care of your needs - if you throw an exception, the default behavior is to reject (and requeue). If you don't throw an exception, the message will be ack'd.</div>

For this I have used AcknowledgeMode.MANUAL , but am not getting how to set the acknowledgement after processing the message in handleMessage method. Can anyone tell me how to do that?<br>
