Overview of this book

<p>Messages and information can be exchanged at exponential speed with JBoss HornetQ asynchronous messaging middleware. Learn how to use the JAVA open source Message Oriented Framework, to build a high-performance, multi-protocol, embeddable, clustered system and manage millions of messages per second.<br /><br />In the HornetQ Messaging Developer’s Guide you will find the most common applications of a message exchanger with example code, as part of real-world scenarios. This practical and applicable guide increases reader knowledge chapter by chapter, covering basics to the most advanced features.<br /><br />You will start from a clean installation of a HornetQ sever and, having progressively become a HornetQ master, will finish by being able to use the framework embedded in your software and sharing information in a cluster environment.<br /><br />Starting from writing and reading a single message, we will discover more advanced features like managing queues, clustering the server, and controlling the undelivered messages. The book deals with a real-world advanced medical scenario as the main example that will lead you from learning the basics to the advanced features of HornetQ.</p>

JMS management API


The general settings that we had for managing HornetQ using the core API are nearly the same for JMS settings. As we explained in Chapter 2, Setting Up HornetQ, HornetQ uses core APIs internally to manage the JMS requests so the only thing that changes is how to call the management API in the correct way.

So we are now ready to re-code the previous example in the JMS dialect only to underline the differences.

Before doing anything we need to create the queue used for testing and to tell HornetQ how to treat the security of the management queue:

  1. Fire up your preferred text editor and open the hornetq-configuration.xml file located in the HORNETQ_ROOT\config\stand-alone\non-clustered folder, and add the following tag into the <security-settings> tag:

          <security-setting match="jms.queue.hornetq.management">
             <permission type="manage" roles="guest" />
          </security-setting>

    The lowest trusted role of security is the guest role. In this case...
