Hi,
Jody is right. The GridCoverageExchange isn't really used for WMS
anymore, but I am surprised it doesn't work (there are test cases). The
API is really really confusing.
Here's a faster way to turn a WMS GetMap Response into a GridCoverage:
BufferedImage image =
ImageIO.read(wms.issueRequest(request).getInputStream());
GridCoverageFactory factory = new GridCoverageFactory();
GridCoverage2D gc = (GridCoverage2D) factory.create("GridCoverage",
image, gtEnv);
Hope that helps,
Richard
