Ok, I put back the "all protocols" acceptor and can get some output.
$ sudo ./artemis browser --destination queue://chat --verbose Executing org.apache.activemq.artemis.cli.commands.messages.Browse browser --destination queue://chat --verbose Home::/opt/apache-artemis-2.14.0, Instance::/var/lib/testbroker Connection brokerURL = tcp://localhost:61616 Consumer:: filter = null Consumer ActiveMQQueue[chat], thread=0 trying to browse 1000 messages Consumer ActiveMQQueue[chat], thread=0 browsing null ...ActiveMQMessage[null]:NON-PERSISTENT/ClientMessageImpl[messageID=2278, durable=false, address=chat,userID=null,properties=TypedProperties[destination=chat,content-length=4,JMSCorrelationID=NULL-value,_AMQ_CONTENT_TYPE=text/plain,JMSType=NULL-value]] Consumer ActiveMQQueue[chat], thread=0 browsed: 1 messages Consumer ActiveMQQueue[chat], thread=0 Browser thread finished This is after I started my client, sent a message, while noone was subscribed. I assume the behavior is to leave it sit there forever, until someone comes and picks it up. Surely there is a limit how many the queue can hold. What happens then? I will test the no acknowledgement scenario now.
