Why do I get the message "Applet not initialized" when I try to open a simple text file??

try {
	file = new FileReader("player.txt");
} catch( FileNotFoundException e ){
	System.out.println("Unexpected Exception: "+e.toString());
}

I''m pretty sure it''s because of the Applet sandbox. You cannot load an arbitrary file from the user''s computer from an Applet. The way to have external files would be to package them in the JAR file, then use ClassLoader''s getResource* methods.

Optuse is correct on this one....

No problems though as you can just read the file from the server the applet is being server from....



/* following method has dependancies....
import java.net.*;
import java.io.*;
*/

/** read url
  *  
  *  @param url_loc location of url to read from
  * 
  *  @return String of url connections or null
  *  
  */
 public static final String read_url(String url_loc) {
  String result = "";
  
  try {
   URL url = new URL(url_loc);
   
   InputStreamReader ins  = new InputStreamReader(url.openStream());
   BufferedReader    in   = new BufferedReader(ins);
   String            line = in.readLine();
   
   for(;line != null; line = in.readLine())
    result += line;
  } catch(Exception e) {
   CS.ex("Read URL exception:", e);
  }
  
  return result;
 }

:-) hope that helps....
