The Java Message Service (JMS) API is:
A Java Message Oriented Middleware API for sending messages between two or more clients.
An implementation to handle the Producer-consumer problem. JMS is a part of the Java Platform, Enterprise Edition, and is defined by a specification developed under the Java Community Process as JSR 914.
A messaging standard that allows application components based on the Java Enterprise Edition (Java EE) to create, send, receive, and read messages.
Enables communication between different components of a distributed application to be loosely coupled, reliable, and asynchronous.
