Trying to Write Files in Java

Question

I've written this; it's one of three classes that work together in a java applet.
import java.applet.*; import java.awt.*; import java.util.*;                            import java.io.*;
class Game{Graphics run(Graphics bufferGraphics, ArrayList<Image> image, Buff buff){
//* Game Code *************************************************************************************************************************//
     bufferGraphics.drawImage(image.get(1),0,0,800,600,buff);
     bufferGraphics.drawImage(image.get(0),100,100,400,300,buff);
     File file = new File ("Meh.dat");
     try{
     PrintWriter out = new PrintWriter(new BufferedWriter(new FileWriter(file)));
     out.close();
     catch(IOException ex)
          bufferGraphics.drawString("Error!", 0, 0);
return bufferGraphics;}}
//*************************************************************************************************************************************//If I take out
     try{
     PrintWriter out = new PrintWriter(new BufferedWriter(new FileWriter(file)));
     out.close();
     catch(IOException ex)
          bufferGraphics.drawString("Error!", 0, 0);
     }It works fine, but with that in there, the other two classes don't work (And it doesn't even write the file). It doesn't even give me my error message, so I'm confused.
The I/O code works fine in a file with system.out.println, so I think it might have to do with the out method/class/whatever.

Answer 1

On that site, it says this:
Can applets read or write files?
In Java-enabled browsers, untrusted applets cannot
read or write files at all. By default, downloaded
applets are considered untrusted. There are two ways
for an applet to be considered trusted:
1. The applet is installed on the local hard disk,
in a directory on the CLASSPATH used by the program
that you are using to run the applet. Usually, this
is a Java-enabled browser, but it could be the
appletviewer, or other Java programs that know how
to load applets.
doesn't being in the same folder/server count as no.1?Yes but in that case you need a permissions file ... don't expect your users to have that or know how to do it. If this is yours and you are running it for yourself or someone you can give the permissions file to, then no you don't need to sign it - you just need to know how to do the grants. search this site for how to do that (tutorial/t-tip/already asked question ... )
