JMS provide for two messaging models, publish-and-subscribe and point-to-point queuing.
Java Message Service (JMS) provides two messaging models:
- Point-to-Point (P2P) Model: In this model, messages are sent from one producer to one consumer. The messages are placed on a queue, and only one consumer can consume a message. The point-to-point model is typically used for asynchronous, reliable communication where each message has only one intended recipient.
- Publish/Subscribe Model: In this model, messages are sent from a producer to multiple consumers. The messages are published to a topic, and any number of consumers can subscribe to that topic to receive the messages. The publish/subscribe model is suitable for scenarios where multiple consumers need to receive the same message.
So, the correct answer is that JMS provides two messaging models: Point-to-Point (P2P) and Publish/Subscribe.
