You need to establish permission for your program to access things on win2K and NT. when you run your program
you should run it with a commandLine option pointing it to a permission file that gives your program permission to access the resources you seek.
The policytool.exe will help you create the appropriate permission file.
Here is an example of a lazy man's policy file
grant {
permission java.security.AllPermission;
};
Here is how you start your program with it
java.exe -Djava.security.policy=filepath -jar ChessOne.jar
I think you can figure out the rest. This is not the only way to use a policy file and I used this back in the 1.3 days so I hope it applies to 1.4 as well...
