Hi
Sorry to dig up an old thread but I'm getting this problem on both
windows and a linux. I'm deploying with maven and have the pure java
jars as dependencies (jai_core, jai_codec, jai_imageio).
I've been using geotools version 2.4.4 (possibly the problem has already
been resolved in the development version). Anyway, in each case I can
only perform the read if I've deployed the native libraries. The code I
use is below, I think it's based on code from a tutorial.
ImageMosaicFormatFactory imfFact = new ImageMosaicFormatFactory();
ImageMosaicFormat fmt = (ImageMosaicFormat) imfFact.createFormat();
if (fmt.accepts(dataIndex)){
ImageMosaicReader reader = (ImageMosaicReader) fmt.getReader(dataIndex);
coverage = (GridCoverage2D) reader.read(null);
reader.dispose();
}
Is there a pure java workaround for this?
Cheers Alistair
