- Provides asynchronous message based communication to Java applications.
- There are two styles of JMS:
- Queues - Messages are stored in queues where they can be processed in the order received.
- Publish and Subscribe - Multiple subscribers are notified when messages are published.
- JMS can guarantee message delivery
- Messages can be processed as part of a transaction. If the transaction is rolled back, the message activity is also rolled back.
