It's clearly a permission error but I cannot solve it

you've got multiple certificates there, they don't really work too well with applets, best to delete all the certificates in the jars and sign everything again with a single certificate.

but the problem happens when I try to read a file out of the jar (a 3ds file)
are you sure?

* (with provided texture, if any) that can be attached to

how can I say to it to look for textures in my jar?
thanks bye
Set up the ResourceLocator correctly.
It needs to point to the Folder containing the textures (don't forget the trailing slash)
new SimpleResourceLocator(your/package/data/textures/);
I need an url
I wrote
location = new SimpleResourceLocator(getClass().getResource( "./media/" ) );
but I get
java.lang.NullPointerException: baseDir can not be null.
