Thanks for the response. I am writing an external java application that reads this values periodically. This will be launched from a unix cron job. Its just a simple tools that periodically checks that the application is available.
I have gone through all the mbeans by using Jconsole but i cant find the one i need that tells me that the application is active and running. I do use Jconsole and jVisualvm and also LamdaProbe but all these require someone to physically log on to look at anything. The tool i am writing will do this automatically and generate an alert if necessary. I just need to know which Mbean to look at. I have found the Datasource ones but not the ones related to the webapplication itsself.
