Hi All,

In a project I have a class, A, that creates a new netcdf-3
(NetcdfFileWriter.createNew(NetcdfFileWriter.Version.netcdf3,
fileNameToSave);) and update it as new output are available. To read the
file I use NetcdfFileWriter.openExisting(fileName).

Now I would like to have a new class, let say B, that opens an
existing netcdf-3 and modifies the values of some variables, just
overwriting them. Again to open the file I use

NetcdfFileWriter.openExisting(fileName);

Running class B I get this error

java.lang.UnsatisfiedLinkError: Unable to load library 'netcdf': The
specified module could not be found.

at ucar.nc2.NetcdfFileWriter.openExisting(NetcdfFileWriter.java:105)

The file exists.

The weird thing is that one I call NetcdfFileWriter.openExisting(fileName);
in class A everything is fine and I get my output file


Thanks for any assistance you can provide.
