7.3. JMS Architecture Overview

We need to understand some of the basics of JMS architecture before using JMS in our application. Here are the players:

JMS Provider

A messaging system that implements the JMS specification. A JMS Provider, also known as a JMS Server, routes messages between clients.

Clients

Java applications that send or receive JMS messages. A message sender is called the Producer, and the recipient is called a Consumer.

Messages

Messages contain data or events exchanged between Producers and Consumers.

Destinations

A Producer sends a message to a JMS Destination (either a Queue or a Topic), and the Consumer(s) listening on the JMS Destination receives the message.

We now will cover messaging models to show how JMS routes messages between Producers and Consumers.
