Hi Jesse:
thanks for that pointer, it fixed my problem and I was able to display GeoTIFF
files with the Mantario Trail SHAPE file superimposed upon them. I currently
have 6 6Mb GeoTIFF files shown.
I tried translating one of our MrSID images into
GeoTIFF to display much more of the trail, but the GeoTIFF ended up being 600Mb
and uDig couldn't seem to handle that. It would be a lot better if uDig
supported MrSID files which we release a lot of our imagery on the MLI here in
Manitoba in. Or else if you can't support MrSID because of proprietary issues
conflicting with the LGPL license then at least if you supported JPEG2000 would
be an option. I couldn't translate this file into ECW because of a GDAL 500k ECW
SDK issue and anyway uDig doesn't support ECW.

This is a frusterating problem that I have not been able to
solve. It seems that sometimes it works and sometimes it doesn't. I
found a hack that works though. in the short cut add:
-vmargs -Dosgi.parentClassloader=ext
that worked for me. I will update the install script.

I am
trying to include 6 GeoTIFF files in my uDig project and am getting errors
when I do this. The error message under the GeoTIFF category is:

can not be read. Could be a JAI configuration problem or a corrupted
file. Error recieved was: java.lang.IllegalArgumentException: ImageRead:

So I listed the information about one of the images using
GDALINFO and got this
