Changing Tomcat's User ID

[jason . majors]

I'm running tomcat 3.2.1 on Solaris. It is started in an rc2.d/ script by
root, and therefore runs as root. We'd like to be able to have it run as
nobody like apache does. Is there a way to do this? I read through the
documentation on it, and it mentioned using su inside of the start scripts,
but that method did not work.
Any help would be greatly appreciated.
Thanks,
