I do have DiskCache.setCachePolicy (true) in my code, along with a call to

i thought i fixed that. are you using the latest version?
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. I was getting
compiler/linker complaints because classes couldn't be found to be imported.
it has been updated, but probably i missed some. which classes where you
seeing missing?
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.
