Nathan,
It's ugly to do it.
You can either bypass security (which I do) so that you can read a file
from an applet. Or you can use ugly code like:
URL iniURL = new URL(codebase, "our.ini");
URLConnection conn = iniURL.openConnection();
conn.connect();
BufferedReader br = new BufferedReader(new
InputStreamReader(conn.getInputStream()));
Beware... URLConnections don't let you write to them (normally). You can
only read.
