Gettting the process id for a VM ...

[Tim Panton - Westhawk Ltd]

the simplest way is to edit your 
startup scripts to say

exec java -DPID=$$ MyMainClass

then you can get the pid with System.getProperty("PID")

But you must ensure that exec is
used throughout any shell scripts.

Alternatively if your ?nix supports
/proc/self/stat, (like red hat 6.0)
then read that file, the first number
is the processID. This is more reliable, but less portable.
