Description: Messaging systems are used to build highly reliable, scalable, and flexible distributed applications. This article discusses messaging systems in general, providing an overview of their features and types, and then describes how developers can write message-based applications using Java Message Service (JMS).Distributed applications are proliferating, as are a host of previously unexplored problems of synchronization, reliability, scalability, and security. One solution is a Messaging System built from loosely coupled components communicating through messages.
