Publish-Subscribe Messaging

Question

Elaborate publish/subscribe messaging?

Answer 1

In publish/subscribe message passing the sending application/client starts a named topic in the JMS broker/server and publishes the messages to this queue. The receiving clients register (specially, subscribe) by the broker to the messages by topic; every subscriber to a topic receives every message published to that topic. There is a one-to-many relationship among publishing client and the subscribing clients.
