Need help reading files from a simple applet

Question

hi everyone,
i have the following problem while trying to read from a file:
java.security.AccessControlException: access denied (java.io.FilePermission dr.xml read)
this problem shows up only when loading applet from a browser... if i use appletviewer everithing is ok.
this is the code:
        cycle = new String[2];
        phase = new String[8];
        v = new Vector();
        int temp;
        try {
            try {
                fis = new FileInputStream("dr.xml");
                while ((temp = fis.read()) > 0) {
                    buf += (char) temp;
                fis.close();
                fis = null;
            } catch (java.io.FileNotFoundException ex) {
                System.out.println("File does not exist. ");
        } catch (java.io.IOException ex) {
            System.out.println("error. ");
            ex.printStackTrace();
        }thanks

You don't have access to the file system. Think about it, you visit a web page and an applet starts reading your files? That's a HUGE security risk.
That said, I think you can do this if you have a signed/trusted applet. Google "signed applets" and "certificates"
