io.filepermission: acces denied

[Reskaillev]

Hi everyone,

Im having this problem where I can't seem to be able to "read" images in JPanels and Jbuttons
because they don't seem to have permission to "read" the image.

Did some research but found nothing...

here are the error messages:

A second one, after removing the activeIcon.gif image (it was an animated gif and I though
maybe the fault would be animation related):

Thnx in advance,

Assuming this is an Applet or Webstart app (which is important information), see the following which applies to both:
What Applets Can and Cannot Do (The Java™ Tutorials > Deployment > Java Applets)

Srry Indeed I forgot to mention that im dealing with an applet here...

Ok it seems I need to make my unsigned applet a signed applet
And do it as described in this link:

http://java.sun.com/developer/online...ok/signed.html

is this correct?
