I've added the GDAL extensions to GeoServer and it worked. However, I followed the instructions in order to add GDAL ECW & MrSID Extensions for GeoServer documented in the installation guide (Adding support for ECW and MrSID on Windows) but I got the error in the screenshot below:
Considering that I've created a GDAL_DRIVER_PATH variable in the environments variables as shown below
And not appearing in the GeoServer. I am using GeoServer 2.8.1
What might be the issue here?


In any case the error looks like a low level error, GDAL related. I suggest to look around for solutions regardless of GeoServer.
