Whether you are looking to move your operations to the Internet and dot-com your business, or are simply looking for ways to get applications to talk to one another, messaging middleware will play a critical role. As computing becomes more network-centric and applications become more distributed, developers are turning to middleware solutions to solve complex inter-process communication issues in a cost-effective and industry-standard fashion. Though traditional messaging solutions have proven to be effective, they are typically proprietary in nature, complicated, and difficult to maintain. Java Message Queue software from Sun Microsystems helps you to realize all the benefits of Message-oriented Middleware without the complexity and compatibility problems of proprietary solutions.     Java Message Queue software implements the industry standard Java Message Service (JMS) 1.0.1 specification, which provides a standardized API and common messaging strategies for developers. Java Message Queue software supports traditional, address-based queues for message delivery, but also includes the speed and flexibility of the asynchronous Publish and Subscribe message delivery model. In this model, messages are routed and delivered based on the properties of the message, not on an address or location. Client processes simply register an interest in a particular topic, allowing Java Message Queue software to intelligently and efficiently handle all the communication needs between application components.
