Sebastopol, CA--Happy Java enterprise developers are all alike; every
unhappy Java enterprise developer is unhappy in his or her own way.
However, quite often this unhappiness stems from the difficulty of
managing increasingly complex enterprise applications and the questions
developers face when grappling with this task: Which management
solution is best for the application? What standards should a
management solution follow? How much effort is required to enable the
components of the application to be managed?
To deal with all these questions, Java Management Extensions, or JMX,
was created. The result of the Java Community Process (JCP) Java
Specification Request (JSR) 3, JMX was designed to address the
management needs of applications written for the Java platform and to
be compatible with existing management standards, such as SNMP (Simple
Network Management Protocol). But the JMX technology is new and
complex, and according to J. Steven Perry, author of "Java Management
Extensions," (O'Reilly, US $34.95) still has a few "potholes" in it.
Perry's book introduces developers to the JMX APIs, providing a
complete treatment of the JMX architecture, (both the instrumentation
level and the agent level). Says Perry, "I've read the JMX
specification--so you don't have to--and have boiled it down into
practical, hands-on advice for using JMX to manage and monitor your
Full of real-world examples for implementing management extensions, the
book takes developers through JMX step-by-step, pointing out the
"gotchas" before they have a chance to trip up smooth operation of the
application. The book also contains useful higher-level information
about JMX to help technical managers and architects who are evaluating
various application management approaches and are considering using
JMX. "Java Management Extensions" covers the following topics:
-Standard MBeans
-Dynamic MBeans
-Model MBeans
-Open MBeans
-The Mbean server
-The JMX notification model
-Dynamic loading
-The timer service
-The relation service
"JMX is an important step forward in managing Java, and more
specifically J2EE, applications, and there is nothing else out there
currently that covers the full specification and reference
implementation," says Perry of his book. And Perry has spent his time
in the trenches. "I've been paged at 3:00 am to provide support because
the system wasn't doing what it should and no one had a clue how to
figure out why. I've scrolled through endless log files to decipher
system problems, when a management solution could have presented an
operator with a warning message hours earlier!"
Written for developers, managers, and any other IT professionals
interested in understanding JMX, "Java Management Extensions" offers
both a "big picture" view and a how-to approach with concrete examples
to help the reader implement the JMX APIs effectively from the start.

"Happy Java enterprise developers are all alike; every unhappy Java enterprise developer is unhappy in his or her own way" - this is a hidden quote from "War and Peace" by L.Tolstoy. Tolstoy was speaking about families, though.
