[rabbitmq-discuss] How to determine if my message was publish successfully

Wed Oct 30 20:42:46 GMT 2013

MK,

I want to capture the basic.return information (replyCode, replyText) if my
basisPublish fails.  I've set the channel to confirm.select and set
mandatory flag to true.  It's my understanding that if an invalid routing
key is provided, the message wouldn't route anywhere and the message should
return to the client since it fail to route to a queue.  I just don't
understand how to implement that in the java code.

channel.basicPublish(strExchangeName, strRoutingKey, true,
MessageProperties.PERSISTENT_TEXT_PLAIN, byteMessage);
