Who Should Use This Book

This guide is meant principally for developers of Java applications that use Sun Java System Message Queue.

These applications use the Java Message Service (JMS) Application Programming Interface (API), and possibly the SOAP with Attachments API for Java (SAAJ), to create, send, receive, and read messages. As such, these applications are JMS clients and/or SOAP client applications, respectively. The JMS and SAAJ specifications are open standards.

This book assumes that you are familiar with the JMS APIs and with JMS programming guidelines. Its purpose is to help you optimize your JMS client applications by making best use of the features and flexibility of a Message Queue messaging system.

This book assumes no familiarity, however, with SAAJ. This material is described in Chapter 5, Working with SOAP Messages and assumes only basic knowledge of XML.
