Permission to read file

Question

Hello,
I'm developing a class that is supposed to read information from a .txt via Scanner(). The file contents give the program instructions on what to draw in a graphics area. The problem is that I keep an AccessControlException saying access is denied.
The code that read the file is as followed:
import java.awt.*;
import java.io.*;
import java.util.Scanner;
public class Map {
     String mapID;
     Tile[] tiles = new Tile[204];
     public Map(String mapID) {
          this.mapID = mapID;
          this.loadMap();
     public Color loadGraphic(String name) {
          Color graphic;
          if(name == "grass") {
               graphic = new Color(0, 255, 0);
          else if(name == "water") {
               graphic = new Color(0, 0, 0);
          else if(name == "path") {
               graphic = new Color(100, 60, 0);
          else
               graphic = new Color(0, 0, 0);
          return graphic;
     public void loadMap() {
          try {
               Scanner mapFile = new Scanner(new BufferedReader(new FileReader(mapID + ".txt")));
               mapFile.useDelimiter(System.getProperty("line.separator"));
               int i = 0;
               int x = 1;
               int y = 1;
               while(mapFile.hasNext()) {
                    String tile = mapFile.next();
                    if(tile != "") {
                         Point coords = new Point(x++, y);
                         int level = Integer.parseInt(tile.substring(tile.indexOf("["), tile.indexOf("]")));
                         Color graphic = loadGraphic(tile.substring(0, tile.indexOf("[")-1));
                         if(tile.indexOf("(") != -1) {
                              Point teleportTo = new Point();
                              //get point for ()
                              tiles[i++] = new Tile(coords, level, graphic, teleportTo);
                         else {
                              tiles[i++] = new Tile(coords, level, graphic);
                         if(i%17 == 0) {
                              x = 1;
                              y++;
          catch(FileNotFoundException e) {
}The class is designed to be used like Map map = new Map("Map ID");, where Map ID is a string of numbers that directs to a file with that name. For example, Map ID 43253 as a file called 43253.txt that has the instructions in it. The ID I'm using is just 1, and the file contents of 1.txt is just 204 lines that say grass[1]. So the map loader is supposed to read the file and create 204 Tile objects with all the information about it. The class I'm about to show then uses that information to draw, in this case 204 32 x 32 squares of green. Eventually they will be varying colors and tiles and the like, but for now I kept it simple.
package com.momentum.tworeborn;
import java.awt.*;
import java.awt.geom.*;
import javax.swing.*;
public class GraphicsScreen extends JPanel {
     static final long serialVersionUID = 7526471155622776147L;
     public GraphicsScreen() {
          this.setPreferredSize(new Dimension(544, 384));
     public void paintComponent(Graphics g) {
          super.paintComponent(g);
          Graphics2D g2 = (Graphics2D)g;
          Map map = new Map("1");
          int x = 0;
          int y = 0;
          for(int i = 0; i <= 203; i++) {
               g2.setPaint(map.tiles.graphic);
               g2.fill(new Rectangle2D.Double(x, y, x+32, y+32));
               if((i+1)%17 == 0) {
                    x = 0;
                    y += 32;
               else {
                    x += 32;
I'm pretty sore not all of that information was needed, but I just wanted to make sure I gave enough information.
Anyway, as I said, I'm getting a access denied when it tries to read 1.txt. I created the file myself, hand typed it an all. Is there any way to give the program permission to read it?

Answer 1

I'm running it as an applet through Firefox 3.5, on Windows XP.
Edit: I have Service Pack 3 and all that as well. Fully Updated.
