I have a Java worker that are polling a external queue system for jobs, through web service calls. What is the most solid way to ensure that the worker is operating at any given time? JVM execution is not different from any other program. So what you want to do is to put together a shell script and place it in /etc/init.d and link it appropriatelly to to /etc/rc.d.

In this script you would have to
