Hi there!
I'm trying to create a coverage in GeoServer 1.7 from a GeoTIFF. Said
GeoTIFF was in turn created by gdal_translate from a mrsid file. I get this
error message:"Invalid url: 'file:coverages/dane.tiff' for format type:'GeoTIFF'.
AFAIR, I've run into such error message because mosaic was unable to
handle a filepath with whitespaces in it.
On Win32 GeoServer dir by default is "C:\Geoserver 1.7.4\" , so I
simply moved data_dir to the "C:\geoserver_data" 
dixi
