Hi,
World Image reader is throwing an exception while setting up the
ParameterBlockJAI. I suspect it is because of incorrect setup of JAI or
something like that. Here's the exception:
java.lang.IllegalArgumentException: The input argument(s) may not be null.

Here's the lines were the exception is thrown:
private void readSourceImage() throws IOException {
if (source == null) {
throw new IOException(
"WorldImage:No source set to read this coverage.");
}
//preparing the parameteres to read the images using a file channel
ParameterBlockJAI readParams = new
ParameterBlockJAI("ImageRead", // this is line 464
"rendered");
This is happening in uDig so it is possible that it is a classloader
problem... But GridCoverage reprojection is working when I create a
GridCoverage by hand.
Any ideas would be great!
