Signing applets/ access controll violations

Question

I have just created a fairly simple game (much like that marble jumping solitare game), that is nice, fine, and works. But, however I run it in applet viewer, which automaticly gives it full power and stuff. If i try to run it in it's webpage, it says that it is not allowed to access the reasource default.txt (the default map file). How can I make it run in a webpage? Would it run on a server? Would it run on a completely seperate folder on a person's computer (aka family)? Can I use other files destributed later for new maps(withough more steps, just read the plain text file--It has the ablity to customise the file loaded)?
To sum it up: can I give something to my mum, so that she can click a shortcut and have it just work?

Answer 1

thawte? I haven't herd of it.
also: this is the code that reads the file:
public void resetBoard() {
  try {
   theFileReader = new FileReader(fileName);
   theReader = new BufferedReader(theFileReader);
   String temp;
   for(int i = 0; i<X_BOXES; i++) {
    temp = theReader.readLine();
    for(int j = 0; j<Y_BOXES; j++) {
     if(temp.charAt(j) == ' ') {
      board[j] = -1;
} else {
board[j][i] = Integer.parseInt(String.valueOf(temp.charAt(j)));
} catch(Exception e) {
System.out.println(e);
by the way, theFile can be changed, to load other files
