Monitoring Java apps in Tomcat6

I've got 3 tomcat6 clusters, with 3 nodes in each.

I've got Hyperic setup to monitor the tomcat6 instances, however, I need to monitor the apps running inside the tomcat6 instances

What is the best way to do this? I know I can setup HTTP monitors, but having to manually set that up does not scale well (I've got 100+ apps to monitor, so creating 300+ HTTP monitors....)

Can this be scripted? I've got almost everything else automated when it comes to adding a new app, so doing something like an HTTP monitor would be OK if I could do it programmaticaly.

Thanks.
