Summary

This book is a thorough introduction to Java Message Service (JMS), the standard API that supports "messaging" -- the software-to-software exchange of crucial data among network computers. Messaging is a key component of today's service-oriented architectures, and with this practical guide, you'll learn how JMS can help you solve many architectural challenges, such as integrating dissimilar systems and applications, increasing scalability, eliminating system bottlenecks, supporting concurrent processing, and promoting architectural flexibility and agility. Updated for JMS 1.1, the second edition of Java Message Service also explains how this vendor-agnostic specification will help you write messaging-based applications, using IBM's MQ, Progress Software's SonicMQ, ActiveMQ, and many other proprietary messaging services. With this book, you will:Build applications using point-to-point and publish-and-subscribe messaging models Use features such as transactions and durable subscriptions to make an application reliable Implement messaging within Enterprise JavaBeans (EJB), using Message Driven Beans Use JMS with RESTful applications, and with the Spring application frameworkMessaging is a powerful paradigm that makes it easier to uncouple different parts of an enterprise application . Java Message Service will quickly teach you how to use the key technology that lies behind it.
