What is /opt/sun-jdk-1.5.0.08/bin/java ? Does it change it's process name at 
all? Maybe you need to use the --name option.

I ask as for init scripts we have a bash wrapper around s-s-d that is a lot 
more strict than s-s-d itself. For example it should only be used for 
daemons - ie what you call is expected to be a daemon. Thus it is useless for 
shell scripts that call daemons. See the courier-imap fiasco for details on 
this.

For hints on what we do, checkout /lib/rcscripts/sh/rc-daemon.sh
