Summary

...grab a copy ofPro JMXat your local bookstore and stick yourself deep into your La-Z-Boy for a relaxing reading experience. - Valentin Crettaz, Val's BlogGet ready to plunge into the complete world of JMX architectureincluding the release of JMX Remoting 1.2!Pro JMX: Java Management Extensionsfeatures cutting-edge examples of JMX integration with distributed applications, including sequence diagrams and real-world sample code.Author Jeff Hanson takes a top-down approach, starting from the highest level of detail and drilling down. In the process, he presents the JMX architecture as a pluggable, services-oriented framework, and discusses how JMX allows you to dynamically add, remove, and modify services at runtime. Hanson also provides in-depth discussions of JMX notifications, event models, and messages.The book finishes up with real-world examples of JMX in use, and features discussions of how JMX is integrated with different management systems and how JMX is used to expose these systems to the J2EE environment.
