title: Can we use JMX for Alerts/Notification
body: <p>Here are the specs that I'm trying to implement in a nutshell:</p>
  
  <p>1) Some Alerts have to be sent on certain events in the application.</p>
  
  <p>2) These Alerts have Users subscribe to them.</p>
  
  <p>3) And the Users have set their own Notification preferences (e.g. Email and/or SMS).</p>
  
  <p>I have not been able to find an open source solution in Java so far.</p>
  
  <p>Is JMX Notifications an option? The more I read about JMX, the more I feel that it is trying to achieve something different that my problem.</p>
  
  <p>Any help would be useful.</p>
