[udig-devel] NPE when loading tif image

[Kelly, Brendon (SAPOL)]

Hi,

I'm using the following code to load a tif map image in my mapeditor.

URL url = new URL(
    "file:///D:/ESRI/maps/adelaide/raster/adlk1205.tif");
List<IService> services =
CatalogPlugin.getDefault().getServiceFactory().acquire(url);
IGeoResource resource = services.get(0).members(new
NullProgressMonitor()).get(0);
List<IGeoResource> resources = new ArrayList<IGeoResource>();
resources.add(resource);
Project project = (Project) ApplicationGIS.getActiveProject();
ApplicationGIS.addLayersToMap(null, resources, -1, project);

In the same directory I have a file called adlk1205.tfw and adlk1205.prj
using GDA94 projection as detailed in the FAQ.  When I run the
application I get:


java.lang.NullPointerException

Is geotools trying to parse a file other than what I've provided?  I
thought that the .tfw file is the world file.  If I load a shape file
using the same code above, everything works fine.
