There are 2 ways of comm with messaging: point-to-point and publish-subscribe.

In p2p there is only 1 consumer. in pub/sub the message is published to multiple subscribers and the subsribers can selectively process the messages using filters. For more details read the 3.5.2 Message Selectors section in jms tutorial.
