In our example, the adapter is accessible through the http://localhost:8080 address, which is defined by the added fields on lines 22 and 23 in Listing 9-27. An instance of MBeanServer is created on line 31, and the adapter is initialized on line 39. The manageable resource is then registered in the MBeanServer component (see line 5). Finally, we define two monitors. (For clarity, the actual code of line 42 is shown in Listing 9-28.) Listing 9-28.

The monitor of line 1 in Listing 9-28 checks the number of incoming orders. Every five orders, the monitor emits a notification event, which is received by the listener of line 13. The monitor of line 20 checks the status attribute of the Stats bean and emits a notification when the attribute s state changes. These notifications are received by the listener of line 34. When run, the application gives the output that is shown in Listing 9-29. Listing 9-29. The Output of the JMX Example JMX notification Order #1 Order #2 Order #3 Order #4 Order #5 JMX notification Order #6 JMX notification Order #7 JMX notification Order #8 Order #9 Order #10 JMX notification JMX notification - Process OK

As you can see, the application emitted notifications as expected. The delay comes from the monitors granularity period, which must be set to 100 milliseconds with the setGanularityPeriod method of the javax.management.monitor.Monitor class. We can now use the HTTP adapter s GUI to reset the Stats class, as shown in Figure 9-6.

Extending a Manageable Resource with an Aspect
Through the use of AOP, we have been able to extend a regular Java class into a manageable resource. In some cases, it is interesting to transparently introduce new functions or attributes. Here, we propose to add a property that contains the mean amount of orders. To do so, we will first modify StatsMBean and StatsMBeanDescription to take the new attribute into account, as shown in Listing 9-30. Listing 9-30. The Enhanced Stats MBean package aop.management.jmx.mixin; public interface StatsMBean { public int getMOrders(); public float getMTotalAmount(); public float getMeanOrderAmount(); public String getMStatus(); public void mReset(); } Next, we will create a mix-in class that implements the new attribute, as shown in Listing 9-31. Listing 9-31. A Mix-in Implementation that Defines the Introduction 01 package aop.management.jmx.mixin; 02 03 public class StatsMBeanMixin implements StatsMBean { 04 05 private Stats advised; 06
