By this chapter, you have seen similar code many times. This class registers the
JMSController MBean in the agent by providing an ObjectName and the class-
name of the MBean.

Writing the MOVIELIGHTSOn and MOVIELIGHTSOff publisher
Now that you have written the MBean and subscriber code, you need a way to
publish the control commands to the JMS bus. The class in listing 13.5 publishes
three messages: MOVIELIGHTSOn , MOVIELIGHTSOff , and doNOTHING . This class repre-
sents the IR signal process receiving commands from a remote control.
