Added an MBean class which can be registered within JBoss as an AlertListener. The JBoss application server comes with 2 built-in AlertListener implementations: console and email. This new class allows alerts to be integrated cleanly into a Nagios monitoring solution. Configuration is defined in the monitoring-service.xml, which is typically found in the deploy directory (or the deploy/monitoring directory, depending on the version). The configuration is very similar to how you would setup log4j, except that there is no need to define mappings between logj levels and Nagios levels. The conf directory in this installation contains an example JBoss setup. This MBean has worked properly using JBoss 3.2.7 and 4.2.2.
