@Gary : thanks for the pointer, this looks like the ideal solution. But I can't make it work, here is some code that does not work as expected : (Note : this is some C# using the NMS API but this is very close to Java+JMS)
[code]// Generate a new unique topic name string retroactiveTopicName = "testRetro_" + Guid.NewGuid() + ".topic"; ConnectionFactory connectionFactory = new ConnectionFactory("tcp://localhost:61616"); var producerConnection = connectionFactory.CreateConnection(); producerConnection.Start(); var producerSession = (Session)producerConnection.CreateSession(); var producer = producerSession.CreateProducer(); var message = producer.CreateTextMessage("First message!"); // Send a first message producer.Send(producerSession.GetTopic(retroactiveTopicName), message); message = producer.CreateTextMessage("Second message!") as ActiveMQTextMessage; // Send a second message producer.Send(producerSession.GetTopic(retroactiveTopicName), message); var consumerConnection = connectionFactory.CreateConnection(); consumerConnection.Start(); var consumerSession = (Session)consumerConnection.CreateSession(); var consumer = (MessageConsumer)consumerSession.CreateConsumer(consumerSession.GetTopic(retroactiveTopicName + "?consumer.retroactive=true")); // Wait for incoming messages consumer.Listener += incomingMessage => { Console.WriteLine("Consumer in : {0}!", (incomingMessage as ITextMessage).Text); }; message = producer.CreateTextMessage("Third message!"); // Send a third message producer.Send(producerSession.GetTopic(retroactiveTopicName), message); System.Console.Write("Press enter to exit..."); System.Console.ReadLine();[/code] The producer sends three messages : two before the consumer is connected, one after. But the consumer only receives the third one, so the "retroactive" flag seems to be completely ignored. What am I doing wrong ?
