I have a small Java class that I want to use to test things. When I type javac classname I always get the message "classname is npt permitted unless annotation is explicitly requested." What's going on here? the class is public class Tryout { public static void main (String[] args) { String osName = System.getProperty("os.name"); System.out.println(osName); } } John -- John J.
