I have tested this, but it continues giving this exception. The getCodeBase() works
correctly (it has to be called from init(), paint() or another applet method but not
from the constructor).
Has anyone been working with this ? Is there any code example ?
Many thanks !!

Hi
I ran into this problem when I first tried texture mapping in Java3D. Due to
the untrusted nature of applets, browsers will not allow them to read or
write to or from the local file system, so the "file:./test.wrl" is the
culprit
Use Applet.getCodeBase() to get the base URL.
For example
s = f.load(new URL(getCodeBase(), "test.wrl"));
