I am using Artemis 2.6.2 with STOMP only and the following constellation: Broker: * No queues configured in broker.xml, everything is auto created.
Server: * SUBSCRIBE to destination "TaskResponse" without selector/filter * SEND to destination "TaskRequest" with header clientId = ID (the ID of the client what the server would request to) Client 123: * SUBSCRIBE to destination "TaskRequest" with selector clientId = 123 * SEND to destination "TaskResponse" with header clientId = 123 When I watch at the Artemis Console the following happens: 1. No server and no client is connected No address or queue is present 2. Server connect Artemis creates a multicast address "TaskResponse" and a multicast queue for this address with empty filter 3. Client 123 connect Artemis creates a multicast address "TaskRequest" and a multicast queue for this address with filter clientId = 123 4. Message exchange Messages are transfered from server to client and back to server as expected. 5. Client 123 disconnect Artemis removes the multicast address "TaskRequest" and the coresponding multicast queue with filter clientId = 123 6. Server sends message to TaskRequest for client 123 According to STOMP client on server the message is sent successful. On the broker the message disappears. 7. Same behavior vice versa: Client 123 is connected and server is not According to STOMP client on client 123 the message is sent successful. On the broker the message disappears. My guess is that the message is discarded because there is no route to a subscriber. If I enable the option "send-to-dla-on-no-route" in address-settings section of broker.xml the message goes directly to dead letter queue. Do you know a way to preserve the messages until the subscriber reconnects? -- Sent from: http://activemq.2283324.n4.nabble.com/ActiveMQ-User-f2341805.html
