Re: [OpenMap Users] Java 1.4.0_02 Problems

Herve,

Thanks for giving me some ideas on this. However, the problem appears
to be that my openmap.properties file is not being read correctly. In
fact, it does not seem to be read at all. When I take my openmap-4.5.3
directory (unchanged) to Windows 2000, it appears to find the correct
openmap.properties file, and produce the desired layers, etc.

This problem is identical to Solaris. I've tried running the openmap
application as root, and it works correctly. I should not have to be
root to do this. I've tried wiping my ${HOME}/.java directory,
wiping /etc/.java, and setting all permissions as open as possible.

Regards,

Eliot
