JMX: Managing J2EE with Java Management Extensions leads you through the JMX
API with thorough coverage of Standard MBeans, Dynamic MBeans, Model MBeans,
the MBean server, and standard agent services. With the help of detailed code
examples, you will learn how to create management systems with JMX, create
MBeans and services, and use the MBean server. This book also offers working
examples of JMX Connectors and agent discovery, a model MBean implementation,
a view of the J2EE Management specification, and a JMX use case using the JBoss
application server.

JMX: Managing J2EE with Java™ Management Extensions About the Authors
About the Authors
Juha Lindfors got involved with the JBoss J2EE application server in early 2000.
While digging into the source, he got a crash course in the JMX API, which was
already part of the server core. Today, apart from trying to learn to write, he spends
a lot of his time writing free software and training people in JMX and J2EE. The rest
of his time is spent trying to figure out what to do when he grows up while studying
Computer Science at the University of Helsinki, Finland.
Marc Fleury, Ph.D., was born in Paris in 1968. Marc started in Sales at Sun
Microsystems France. A graduate of the Ecole Polytechnique, France's top
engineering school, and an ex-Lieutenant in the paratroopers, he has a master in
Theoretical Physics from the ENS ULM and a Ph.D in Physics for work he did as a
visiting scientist at MIT (X-Ray Lasers). Marc currently serves as the President of the
JBoss Group, LLC? n elite services company based out of Atlanta, GA.
The JBoss Group LLC, is a service company dedicated to support, training, and
consulting around the free JBoss platform. Based in Atlanta, GA, this LLC regroups
core JBoss programmers around the world. JBoss is an open-source,
standards-compliant, J2EE application server implemented in 100 percent pure
Java. The JBoss/Server and complement of products are delivered under a public
license. With 50,000+ downloads per month, JBoss is arguably the most
downloaded J2EE-based server in the industry.

Acknowledgments
I'd like to thank Marc Fleury for his excellent insights into JMX and for kicking my
arse to keep me moving. I also much thank Andreas Schaefer for h is help in
covering some of the difficult parts of the book. My thanks to all the folks at Sams
who made this book real, especially Christy Franklin for her help and comments to
get the chapters finished, and the Technical Editor, Kevin Farnham, for putting up
with my buggy Java command-line instructions. To Mikko and Tuomo, thanks for
dragging me out for an occasional movie or a game of squash. There are numerous
other people to thank I can't remember right now. JBoss developers should be
proud of your work. And of course, I would like to thank the Academy.

JMX: Managing J2EE with Java™ Management Extensions Introduction
Introduction
The Java Management Extensions defines architecture for software and network
management in the Java programming language. This book will cover the JMX
specification and show you how resources can be managed using JMX.
What is JMX?
JMX is a unified framework to instrument the disparate pieces of Java code in a
modern IT infrastructure. Before JMX, there was no standardized approach in the
Java programming language to start, manage, monitor, and stop different software
components or applications. Management of software has been achieved through
an ad-hoc collection of procedures and custom management code. JMX promises to
remove the need for expensive application-specific management solutions by
defining an architecture that allows more generic management applications to be
built.
Why JMX for J2EE?
The Java 2 Enterprise Edition is a complex, distributed, service-based enterprise
platform. It consists of many different kinds of resources that are dynamically
created, distributed, moved across nodes, redeployed, and destroyed. The
management of such a platform calls for an isolation layer between the
management applications and the managed resources. The management
architecture must be generic enough to allow a wide variety of different kinds of
resources and components to be managed. The management architecture must be
able to cope with the dynamics and distribution of the platform and provide a
management model that allows increasingly long uptimes and 24x7 services. JMX
can provide all this.
Part I: Java Management Extensions
Specification
The first part of this book will cover all the aspects of the JMX specification. Several
examples will be implemented to demonstrate how to build management
components, discuss the different types of components the JMX specification
defines, and look at the management architecture established by the JMX
implementations.
