&gt; I want to capture the basic.return information (replyCode, replyText) if my basisPublish fails. �I&#39;ve set the channel to confirm.select and set mandatory flag to true. �It&#39;s my understanding that if an invalid routing key is provided, the message wouldn&#39;t route anywhere and the message should return to the client since it fail to route to a queue. �I just don&#39;t understand how to implement that in the java code.<br>

<br>
</div>Publishing is asynchronous, so is returning of messages to the client.<br>
You need to register a handler for returned messages. This can be used in combination<br>
with publisher confirms, as necessary.<br>
