Applet works in appletviewer, but not in browser

java.security.AccessControlException: access denied (java.io.FilePermission words.txt read)


There is the error in my Java Control Panel Console thingy when I try to load my applet in a browser. I've tried IE and FireFox. Are applets unable to read files located in the same directory as the applet? Or is there something simple I have to change?

Code:

---

                // build the dictionary tree
                String dictionaryFN = "words.txt";
                try
                {
                        BufferedReader fin = new BufferedReader(new FileReader(dictionaryFN));
                        String word = fin.readLine();
                        while (word != null)
                        {
                                dictionary.insert(word);
                                word = fin.readLine();
                        }
                        fin.close();
                }
                catch (FileNotFoundException e)
                {
                        System.err.println("FileNotFoundException: " + e.getMessage());
                        return false;
                }
                catch (IOException e)
                {
                        System.err.println("IOException: " + e.getMessage());
                        return false;
                }

There is the code in question. Maybe I'm doing something wrong? Any help is appreciated.

You can't read files off the harddrive in an Applet, it's part of the Java sandbox security model. If you package everything in a jar file, you can then access files as resources. I can give you code examples if you need them (it's been a while since I've done it and would have to look it up).

Thanks, that makes sense. I'll jar it up then, I'm sure I can figure out the resource thing on my own. :)
