Hello,
I 'm trying to use GT 2.3, in order to create a map viewer (Shapefile,
Geotiff, etc ...). Displaying Shapefiles work perfectly, but when i m
trying to add a Geotiff layer based on GridCoverage2D in my
MapContext, I've got this :
private GridCoverage2D _loadFromTifFile(String filepath)
{
File tif = new File(filepath);
GeoTiffReader reader = (GeoTiffReader) ((new
GeoTiffFormat()).getReader(tif));
try {
return (GridCoverage2D) reader.read(null);
} catch (IOException e) {
e.printStackTrace();
}
return null;
}

I tryied to load a real GeoTiff file ,and a Tif+tfw file, it's not the
same class but the same error. So i decided to open the
GeoTiffReader.java, and try to find the reason of this error.
It seems to be all the JAI.X static methods, that raise this exception
but why and of course how to solve that ?
Thanks for all.
