Hello list,

I'm trying to make an applet display a geotiff coverage. I first tried
to make the code run as a java application. So far so good. Then I
changed the code to make it an applet.
The applet runs fine through appletviewer but fails through the web
browser. There are 2 errors: one is related to jpeg and the other is
related to tiff. Here they are:

# display tiff coverage #

I understand that the first issue seems to be related to the
imagereader and the second seems to be a transformation issue. But it
works fine through the appletviewer which makes me think that it is
probably a missing library issue. Could you please help me ?

Basically the applet allows the user to select a file in the local
file system (jpeg or tiff). Then it shows the coverage image.
The applet's jar is signed in order to run outside the security
sandbox to allow local file system access. I checked that every
required jar (geotk + extra) is provided with the applet. Every
dependent jar had to be signed as well. Please let me know if you want
me to provide the code.

Kind regards,
Ramzi
