I'm using a 4.3 bundle that I downloaded a couple days ago. The NJ and GRIB jars are both timestamped Feb. 9. I just doublechecked to see if using a custom cache directory otherwise worked by opening a compressed NC file. NJ created the uncompressed version in the specified cache dir. >> BTW: Something else I was running into last night is that the discussion of >> runtime loading of GRIB tables and lookup lists at >> http://www.unidata.ucar.edu/software/netcdf-java/reference/RuntimeLoading.html >> doesn't seem to have been updated for the latest NJ-4.3.

The webpage says that to open a lookup list... Register a GRIB1 or GRIB2 lookup table (version 4.3): ucar.nc2.grib.grib1.Grib1ParamTable.addParameterTableLookup(String lookupFilename); ucar.nc2.grib.grib2.tables.Grib2Tables.addParameterTableLookup(String lookupFilename); I am getting complaints that neither ucar.nc2.grib.grib1.Grib1ParamTable or ucar.nc2.grib.grib2.tables.Grib2Tables is available. It looks like I can replace the GRIB-1 call by instead trying ucar.nc2.grib.grib1.tables.Grib1ParamTables.addParameterTableLookup(lookupFilename); Note different package and class name. I haven't figure out what to replace the GRIB-2 call with, but at the moment that doesn't matter as I don't have a user's sample GRIB-2 table or lookup list to test it on anyway. I haven't yet tried a straight open of a GRIB table without going through an intervening lookup list, but again, when I look at the examples on the webpage Register a GRIB1 or GRIB2 table (version 4.3): ucar.nc2.grib.grib1.Grib1ParamTable.addParameterTable(int center, int subcenter, int tableVersion, String tableFilename); ucar.nc2.grib.grib2.tables.Grib2Tables.addParameterTable(int center, int subcenter, int masterVersion, int localVersion, String tableFilename); it doesnt't look right. The GRIB-1 looks, again, like it's missing the .tables. from the package path. The GRIB-2 .tables. package just isn't there. rbs -- Robert B.
