Hi, First, I would recommend using the camel-jms component. Remember that activemq-camel is not deprecated, and camel-activemq doesn't bring much compared to camel-jms.
Back on your point, you have to provide the destination type on the URI (queue or topic). So the activemq endpoint URI should look like activemq:queue:foo where foo is the name of the queue.
