Well, I've been trying all day to list a directory in Java (under Win95 with Explorer 5.0), only to get an "AccessControlException : Permission denied" message. So, I've read the documentation of Policytool and put .java.policy file in my profile(giving myself all possible permission over this directory). It didn't change a thing. Besides, I didn't quite understand how to give permissions or forbid users from giving permissions to themselves. I mean, if anybody can give himself any permission he wants, it doesn't make sense.
