Java Messaging Service (JMS)

The Java Messaging Service (JMS) is a standard API for accessing enterprise messaging systems.

JMS is an enterprise messaging system, also referred to as message-oriented middleware (MOM), enables applications to communicate with one another through the exchange of messages. A message is a request, report, and/or event that contains information needed to coordinate communication between different applications.

A message provides a level of abstraction, allowing you to separate the details about the destination system from the application code.

JMS (Java Messaging Service) Features

• Enables Java applications sharing a messaging system to exchange messages.
• Simplifies application development by providing a standard interface for creating, sending, and receiving messages.
• JMS specification describes a common way for Java programs to create, send, receive and read distributed enterprise messages.
• Loosely coupled communication
• Asynchronous messaging
• Reliable delivery where a message is guaranteed to be delivered once and only once

MOM Stands for Message Oriented Middleware. MOMA (Message Oriented Middleware Association) promotes MOM as a middleware solution in distributed computing applications.

MOM mainly addresses the following issues

• Asynchronous communication between objects available on locations on the network
• Fault tolerance feature in Distributed Application Development
