Hi Dan:

This is a bug using reletive filepaths, will be fixed in next release.

use absolute path

/home/you/ecmwf_yotc.ana.eta.D91.20090916_00z.grib


instead of

ecmwf_yotc.ana.eta.D91.20090916_00z.grib

Some environment settings
echo $JAVA_BINDIR
/gpfsm/dnb52/projects/p10/dkokron/play/JAVA/jre1.6.0_31/bin
dali05.dkokron 272>  echo $JAVA_HOME
/gpfsm/dnb52/projects/p10/dkokron/play/JAVA/jre1.6.0_31
dali05.dkokron 273>  echo $JAVA_ROOT
/gpfsm/dnb52/projects/p10/dkokron/play/JAVA/jre1.6.0_31

The corresponding task using
toolsUI-4.0.jar ucar.nc2.iosp.grib.Grib2Netcdf
works fine.
