applet NullPointerException

Question

I've been working on a game in an applet. In Eclipse it has been working completely fine, but when I sign it and load it in my browser, it throws a NullPointerException, without any further information. What can I do?

Answer 1

You don't give very much information here, but I can make a guess that you are calling getAppletContext and it is returning null, because the browser's java implementation is broken. Try the applet viewer, and try a different browser, and see if it works there.

Answer 2

That happen to me once. You'll need to go to:

• Configure Java.
  • Security.
  • Exception List
  • Edit the list adding the directory of your applet.

This, I think, should fix the problem!
