Schedule Message Delivery
26.1. Scheduled Delivery Property The property name used to identify a scheduled message is "_HQ_SCHED_DELIVERY" (or the constant Message.HDR_SCHEDULED_DELIVERY_TIME). The specified value must be a positive long corresponding to the time the message must be delivered (in milliseconds). An example of sending a scheduled message using the JMS API is as follows. TextMessage message = session.createTextMessage("This is a scheduled message message which will be delivered in 5 sec."); message.setLongProperty("_HQ_SCHED_DELIVERY", System.currentTimeMillis() + 5000); producer.send(message); ... // message will not be received immediately but 5 seconds later TextMessage messageReceived = (TextMessage) consumer.receive(); Scheduled messages can also be sent using the core API, by setting the same property on the core message before sending.
