# ============================================================================== # # JMX Tutorial Introductory Example : Instrumenting Your Own Applications. # Using Notifications. # # This example is the same as the previous essential example with the # only difference that the Hello World MBean has been modified to send # notifications. # # The Hello World MBean implements the NotificationBroadcaster interface # by extending the NotificationBroadcasterSupport class and emits # AttributeChangeNotifications every time the CacheSize attribute # is changed. # # ============================================================================== # # In order to compile and run the example, make a copy of this README file, and # then simply cut and paste all the commands as needed into a terminal window. # # This README makes the assumption that you are running under Java SE 6 on Unix, # you are familiar with the JMX technology, and with the bourne shell or korn # shell syntax. # # All the commands below are defined using Unix korn shell syntax. # # If you are not running Unix and korn shell you are expected to be able to # adapt these commands to your favorite OS and shell environment. # # Compile Java classes # # The Java classes used in this example are contained in the com.example.mbeans # Java package. # # * Main.java: gets the Platform MBean Server, and creates # and registers the Hello World MBean on it. # # * Hello.java: implements the Hello World standard MBean. # This MBean emits notifications every time # the CacheSize attribute is changed. # # * HelloMBean.java: the management interface exposed by # the Hello World standard MBean. # javac com/example/mbeans/*.java # Start the Main application # java com.example.mbeans.Main # Start jconsole on a different shell window on the same machine # # JConsole is located in $(J2SE_HOME)/bin/jconsole # jconsole # ==============================================================================
