Hi,
I am trying to load an ECW map with GeoTools but I am having some problems
so I have been unable to achieve this.
As I read in the GeoTools user's guide, I have downloaded and configured
the imageio and imageio-ext libraries, and I have added the Maven
dependencies to my project.
I have also copied the GDAL native libraries and installed de ECW SDK for
read only (downloaded form the ERDAS page)
When executing gdalinfo I can see that GDAL is correctly installed and
reviewing the project libraries I found the imageio-ext libraries (version
1.0.8). I am using GeoTools 2.7.2 version in Windows XP
My code is based on the ImageLab tutorial, but when executing the following
instance:
AbstractGridFormat format = GridFormatFinder.findFormat( rasterFile )
I get this exception
Exception in thread "main" java.lang.UnsupportedOperationException: Trying
to get a reader from an unknown format.
at
org.geotools.coverage.grid.io.UnknownFormat.getReader(UnknownFormat.java:62)
at org.geotools.test.LoadECWMap.displayLayers(LoadECWMap.java:87)
at org.geotools.test.LoadECWMap.getMapAndDisplay(LoadECWMap.java:134)
at org.geotools.test.LoadECWMap.main(LoadECWMap.java:139)
This code works perfectly with TIF maps.
If I change the code to use directly an ECWFormat object:
ECWFormat format = new ECWFormat();
reader = format.getReader(rasterFile);
it raises the following exception:
Exception in thread "main" java.lang.RuntimeException: The Provided input
is not supported by this reader

The ECW map is ok and a can see it with IrfanView using the appropriate
plugin.
What am I doing wrong? Is there anything that I am missing?
Thanks in advance.
Regards.
