In-Depth Information
After executing this command script, you now have everything running for your
test application. In order to see things work, you need to publish control mes-
sages to the message bus. The next section describes the process of running the
JMSPublisher
class that you built to publish control messages.
13.4.4
Publishing the control messages
Your publisher class will publish three messages to the message bus. The first two
messages drive your MBean functionality, and the third message causes your
MBean to print a message to the screen indicating that it is not interested in the
message. Listing 13.8 shows the command script required to run the publisher.
Again, notice the reference to the
JMS
JAR
s from the JBoss provider.

Congratulations—you just successfully integrated

with

.
13.5 Summary
This chapter presented the idea of integrating
JMX
MBeans into your Java Mes-
sage Service applications. Due to the non-intrusive nature of
JMX
, you can build
a window into your
JMS
applications using
JMX
MBeans. By writing MBeans that
