exception in initializer error?

P: 59
I created a japplet in java and put it on website. there are no errors in eclipse and it works fine.

on web it say "Error - click for details". when i click on it, it says 'ExceptionInInitializerError' but no details.

does the error has to do with the code below?

  1. public void run()
  2.     {
  3.         while(!player_class.isDEAD())                         
  4.               {
  5.             ....    
  6.             repaint();
  7.             try
  8.             {
  9.                 Thread.sleep(10);
  10.             }
  11.             catch(InterruptedException e)
  12.             {
  13.                 e.printStackTrace();
  14.             }    
  15.         }/*** end of while loop ***/
  16.     }/*** end of run method ***/

According to the java api docs, this Error is thrown when there's a problem in a static initializer. So, while the above code may CALL something static, there's no way for us to know without more context.

I would suggest checking everything static for errors. Everything else depends on code you haven't posted.

by static do you mean static variable or method?

bc i have some static variables:

private static final long serialVersionUID = 1L; //in main
public static final int WINDOW_WIDTH = 900; //in main
public static final int WINDOW_HEIGHT = 400; //in main
public static final int DELAY = 15; //in main

Those look ok, at least out of context. I am however a little confused by the comment
Expand|Select|Wrap|Line Numbers
  1. //in main
after every line. Are they in a main method? If so, that main method won't be called when running the code as an applet (unless you call it manually). So everything in that method needed for the applet to run would have to be moved elsewhere (e.g. into the run method).

Also, please use [code] tags for posting code.

Hm, it shouldn't be... Is there anything else that's static? And when you click on click for details (you know, where you got the ExceptionInInitializerError), is there anything clickable there? There should be a stacktrace or something. Alternatively, the server you're running should have a log file in which you can check the details. Somewhere there it should tell you what line of code caused this error.
