(Please stop sending your questions to all three groups, as many people are
subscribed to all of them, and are getting several copies of each question.)
If you are running this from an applet, the applet classloader is blocking
access outside the directory the class was loaded from. That's on purpose.
Here's a test file which demonstrates directory listing. (If it doesn't
compile with the alpha compiler, adjust as needed.) Run it using the java
interpreter, *not* as an applet.
import java.io.File;
import java.io.IOException;
public class test {
public static void main(String argv[]) {
File f = new File("/tmp");
String files[] = null;
try {
files = f.list();
} catch (IOException e) {
System.out.println("Failed listing /tmp: ");
e.printStackTrace();
System.exit(1);
}
System.out.println("Files in /tmp:");
for (int i = 0; i < files.length; i++) {
System.out.println("\t" + files[i]);
}
}
}
