Hello Jin, since you are writing NetCDF-4, also check the NetCDF-C library version in your system, it has to be 4.2.1 or above (http://www.unidata.ucar.edu/software/netcdf-java/reference/netcdf4Clibrary.html). I've just run the code you posted and the only problem I see is that: file.findGroup("root"); returns null. Also, the directory "data" for the path "data/foo.nc" must exist. NetCDF-JAVA won't create it. Have you tried with the path "foo.nc" ? And yes, from ftp://ftp.unidata.ucar.edu/pub/netcdf-java/v4.3/netcdfAll-4.3.jar you get the latest version of the NetCDF-JAVA library. However, yesterday we released 4.3.16 and that's the latest now so I recommend you to update (although I don't think this new version makes any difference in this case). Cheers! Marcos Hermida.
