Hi, guys: I want to deal grib file with IDL 8.3 and Netcdf-java in windows 7 64bit. I run the fellowing code: oNetcdfDataset = OBJ_NEW("IDLJavaObject$NetcdfDataset", "ucar.nc2.dataset.NetcdfDataset") NetcdfFileObj = oNetcdfDataset->openDataset("GLDAS_VIC10_M.A201305.001.grb") In IDL workbench "idlde.exe", I get the errors, which shows that java bridge could not open the resource files in jar: IDL> oNetcdfDataset = OBJ_NEW("IDLJavaObject$NetcdfDataset", "ucar.nc2.dataset.NetcdfDataset") IDL> NetcdfFileObj = oNetcdfDataset->openDataset("GLDAS_VIC10_M.A201305.001.grb") % May 25, 2014 9:48:52 AM ucar.nc2.grib.grib1.tables.Grib1ParamTables$Lookup readLookupTable WARNING: Could not open table file:resources/grib1/lookupTables.txt % May 25, 2014 9:48:52 AM ucar.nc2.grib.grib1.tables.Grib1ParamTables$Lookup readLookupTable WARNING: Could not open table file:resources/grib1/ecmwf/lookupTables.txt % May 25, 2014 9:48:52 AM ucar.nc2.grib.grib1.tables.Grib1ParamTables$Lookup readLookupTable WARNING: Could not open table file:resources/grib1/ncl/lookupTables.txt % May 25, 2014 9:48:52 AM ucar.nc2.grib.grib1.tables.Grib1ParamTables$Lookup readLookupTable WARNING: Could not open table file:resources/grib1/dss/lookupTables.txt % May 25, 2014 9:48:52 AM ucar.nc2.grib.grib1.tables.Grib1ParamTables$Lookup readLookupTable WARNING: Could not open table file:resources/grib1/wrf/lookupTables.txt % May 25, 2014 9:48:52 AM ucar.nc2.grib.grib1.tables.Grib1ParamTables$Lookup getParameterTable WARNING: Could not find a table for GRIB file with center: 0 subCenter: -1 version: -1 % Exception thrown % Execution halted at: $MAIN$ But with idl.exe command, it works OK.
