Re: [OpenMap Users] Java 1.4.0_02 Problems

Maybe when you are running as root, your home directory is /root, and
it (JVM) succeeds in opening a file (openmap.properties?) there, but
not running as root, it doesn't succeed in reading a file in /root.

I'm on a Mac OS X machine right now, but I have a RH7.3 machine handy
with JDK1.4, so I'll try there and see what gives.
