Applet-subclass-image-handle-problem

[Benjamin Hössl]

Hi NG,
I have a problem with the Toolkit.getDefaultToolkit().getImage(String, int)
method. In the normal Applet viewer there is no problem with getting
pictures with this method, but when I try to run in a browser e.g. Internet
Explorer or Netscape, i get security probs. I'm using this method in a
subclass.
However the problem can be worked around by using
applet.getImage(getCodeBase(),String) but there is my problem. To be able to
use this method, my class must extend Applet as far as I can see. But when I
let my subclass extend Applet plus my mainclass extends Applet I'm not
getting any pictures but NullPointerExceptions.

My Question: Is there any possibility to use a secure method to get Images
into an array in a subclass?

Thanks for your help
