Learn the basics of messaging, a powerful paradigm that makes it easier to decouple and integrate enterprise applications. In this video course, messaging expert Mark Richards takes you through messaging fundamentals with the Java Message Service (JMS) API. You’ll learn the basics of how to use the JMS 1.1 and 2.0 API to send and receive messages, how to do request/reply processing, how to use message selectors, and how to use publish and subscribe messaging—all through live, interactive coding with ActiveMQ and OpenMQ.

This video begins with some fundamental messaging concepts, then takes you on a live coding journey through the JMS 1.1 API, the new JMS 2.0 simplified API, then a variety of messaging fundamentals topics that will enable you to understand and effectively use messaging for enterprise-wide applications.

Topics include:

• Core messaging concepts, including guaranteed delivery and the difference between point-to-point and publish-and-subscribe messaging
• New JMS 2.0 features, including shared subscriptions, asynchronous send, delivery delay, and delivery count
• Standard, extended, and application message header properties
• Techniques for request/reply messaging—when you require a response from the receiver
• Publish-and-subscribe messaging, including the various types of subscribers and guidelines for using them
• Uses and limitations of message selectors, which specify conditions for receiving messages
• How the three message acknowledgement modes work and when to use each

Once you complete this video course, you’ll be ready for the follow-up: Enterprise Messaging Using JMS: Advanced Topics and Spring JMS.

'Clearing a path from developer to architect and enriching that path once you arrive.'

Software architecture is a fast-moving, multidisciplinary subject where entire suites of “best practices” become obsolete practically overnight. No single path or curriculum exists, and different types of architecture—application, integration, enterprise—require different subject emphasis. Whether you’re at the outset of a career as an architect or in the midst of such a career, series editor Neal Ford has curated this collection of tools and guides for aspiring and seasoned architects alike.
