Deleting a single message from topic

[dms]

Is it possible to delete a single message from a topic? We tried the following approach but this deletes all messages up to the one we want to get rid of:

        TopicSession jmsSession = jmsConnection.createTopicSession(false, ActiveMQSession.INDIVIDUAL_ACKNOWLEDGE);

        Topic topic = new ActiveMQTopic(destinationName);

        TopicSubscriber consumer = jmsSession.createDurableSubscriber(topic, subscriptionName);

        Message message = consumer.receive(1000l);

        while (null != message) {

            try {

                if (messageID.equals(message.getJMSMessageID())) {

                    message.acknowledge();

                }

                message = consumer.receive(1000l);

            }

            catch (JMSException e) {

            }

        }

Best regards

The individual ack mode is not supported for durables at the moment. There is a fix in 5.6 to flag this as an error.

https://issues.apache.org/jira/browse/AMQ-3486

The problem is that the store just keeps track of the latest acked sequence number and has a shared message store. To support individual ack mode, would require backing each durable with a queue.

You could look at using Virtual topics in place of Durables, in this case, consumers subscribe to a queue and the virtual topic dispatches to each of the subscription queues.
