I have GeoServer on Ubuntu 14 as part of a Geonode 2.6 install. I am having trouble installing the GDAL extensions. The version of GeoServer says 2.9-SNAPSHOT.
I have tried to install the GDAL extensions following the instructions here - http://docs.geoserver.org/2.9.3/user/data/raster/gdal.html
I used the GeoServer 2.9.4 GDAL extensions. After restarting GeoServer, the additional coverage formats aren't available.
gdalinfo --version returns the correct version, and gdalinfo --formats returns the list of supported formats.
I can't find anything obvious in the log file, there is a reference to - ArcSDE Java API seems to not be on your classpath. Please verify that all needed jars are. ArcSDE data stores will not be available.
and then
2017-06-27 03:31:35,393 DEBUG [gdal.envihdr] - EnviHdrFormatFactory is not availaible. 2017-06-27 03:31:35,393 DEBUG [gdal.jp2mrisd] - JP2MrSIDFormatFactory is not availaible. 2017-06-27 03:31:35,393 DEBUG [gdal.jp2ecw] - JP2ECWFormatFactory is not availaible. 2017-06-27 03:31:35,393 DEBUG [gdal.mrsid] - MrSIDFormatFactory is not availaible. ...........etc
I have updated the \etc\environment file to include the path, still nothing.
