I have downloaded the nctoolbox (version: nctoolbox-1.1.0) to read the grib2 file from http://nomads.ncep.noaa.gov/pub/data/nccf/com/cfs/prod/cfs/cfs.20160308/00/6hrly_grib_01/. The java error always occured. I didn't know why. Could you help me? My matlab version is 8.1.0.604 (R2013a). The error information will be list below.
