Subject Re: Help with Camel Config routing using a custom ActiveMQ Message Property
Date Fri, 24 Jun 2016 02:19:48 GMT
I had a similar use case in the past, and I chose to route the "trash"
messages to a JMS Topic that didn't have any durable subscribers.  That way
I could create a subscriber when I needed it to see what was being
"trashed" - just be careful you don't create a durable subscriber or the
messages will build-up in that topic.
