About the JMS Publish-and-Subscribe Model

The traditional message model, where a message is sent to a queue and later removed by a single receiver, is called point-to-point messaging. In addition to this familiar model, JMS also supports the publish-and-subscribe messaging model. Here, messages are published to topics, rather than sent to queues. Interested receivers subscribe to individual topics and receive a copy of each message published to the topic. In order to subscribe, a subscriber registers with the topic, providing a unique identifier. For more information about the JMS publish/subscribe model, refer to the specification that is available from Sun at http://java.sun.com/products/jms.
