(Syntax below is not exactly correct, but has the right idea)
Assuming you loadlancer worker is named loadbalanceworker which has workers tomcat1worker and tomcat2worker
Instead of JkMount *.jsp loadbalanceworker
Try this JkMount /testworker1page tomcat1worker JkMount /testworker2page tomcat2worker

Could you please explain what do you mean special (hidden) and how to do it? Currently I only define on JkMount for loadbalancer. Thanks, -Simon

For the load balanced tests, have a special (hidden) JkMount for each tomcat
in the cluster.

I can come up with a WatchDog to do the monitoring/restart. But We have a few tomcat instance runing in load balance mode with one Apache

question
is can we bypass Apache to go directly to Tomcat since we know where they are?

Some commercial monitoring products perform a request to an (unprotected) URI and, in the event of a failure, perform some specified action. -that is, call the start script.
Otherwise, you could have Tomcat started by a (custom) watchdog, the idea being that it kicks the start script if the expected process isn't running. I recall iPlanet 4 did something similar.
As for free + out-of-the-box solutions, I haven't seen any...
