By using the following

MBeanServerConnection mbsc = (MBeanServerConnection) ctx.lookup("jmx/invoker/RMIAdaptor");
//

ObjectName serverInfo = new ObjectName("jboss.system:type=ServerInfo");
mbsc.addNotificationListener(serverInfo, this, null, null);

And then placing the following listner in my class

 public void handleNotification(Notification notification, Object handback) {

 System.out.println("\nReceived notification:");
 System.out.println("\tClassName: " + notification.getClass().getName());
 System.out.println("\tSource: " + notification.getSource());
 System.out.println("\tType: " + notification.getType());
 System.out.println("\tMessage: " + notification.getMessage());
 if (notification instanceof AttributeChangeNotification) {
 AttributeChangeNotification acn =
 (AttributeChangeNotification) notification;
 System.out.println("\tAttributeName: " + acn.getAttributeName());
 System.out.println("\tAttributeType: " + acn.getAttributeType());
 System.out.println("\tNewValue: " + acn.getNewValue());
 System.out.println("\tOldValue: " + acn.getOldValue());
 }

 }
