Preface

This Message Queue Developer’s Guide for JMX Clients describes the application programming interface provided in Sun Java System Message Queue 4.0 for programmatically configuring and monitoring Message Queue resources in conformance with the Java Management Extensions (JMX). As in earlier versions of Message Queue, these functions are also available to system administrators by way of the Message Queue Administration Console and command line utilities, as described in the Message Queue Administration Guide. The API described here, new in release 4.0, makes the same administrative functionality available programmatically from within a running client application.

Message Queue 4.0 also includes several new broker properties and command-line options to support the new JMX API. These features are described in the Message Queue Release Notes for release 4.0, and will eventually be incorporated into the Message Queue Administration Guide.

Who Should Use This Book

This guide is intended for Java application developers wishing to use the Message Queue JMX API to perform Message Queue administrative tasks programmatically from within a client application.

Before You Read This Book

This guide assumes that you are already familiar with general Message Queue concepts, administrative operations, and Java client programming, as described in the following manuals:

• Message Queue Technical Overview

• Message Queue Administration Guide

• Message Queue Developer’s Guide for Java Clients

You should also be familiar with the general principles of the Java Management Extensions, as described in the following publications:

• Java Management Extensions Instrumentation and Agent Specification

• Java Management Extensions (JMX) Remote API Specification

Together, these two publications are referred to hereafter as the JMX Specification.

How This Book Is Organized

This guide consists of the following chapters:

• Chapter 1, Introduction to Message Queue JMX introduces the basic concepts and principles of the Message Queue JMX interface.

• Chapter 2, Message Queue MBean Reference provides detailed information on the attributes, operations, and notifications provided by Message Queue managed beans (MBeans).

• Appendix A, Alphabetical Reference lists the MBean attributes, operations, and notifications alphabetically, with references back to their descriptions in the body of the manual.
