Perhaps JNI is the best approach. I don't know.
But I do know that using JNI makes Java code not
write-once-run-anywhere. That is partly because the non-Java code must
be available for all target platforms. Even if it is available, JNI can
be very picky -- code has to be compiled with certain versions of
compilers and with certain flags. So, using JNI can seem relatively
straight-forward for the initial developer ("it works for me"), but be
an installation headache for others trying to reuse the code.

NetCDF-Java Folks,
We have a need to write NetCDF4/HDF5 files from within a project that
already has a significant framework developed in Java. We also have a
firm requirement to be able to "append" to existing files - which
(unfortunately) takes the Nujan library off the table (at least in it's
current incarnation). I see from the NetCDF-Java FAQ
(http://www.unidata.ucar.edu/software/netcdf-java/reference/faq.html#Writing)
that you are considering a JNI approach for writing NetCDF4 from NJ, and
I'd like to put my vote in for that. The HDF Team supports JNI Java
modules for Windows, Linux and Mac - wouldn't it be relatively
straightforward to integrate those into the NetCDF-Java distro to give
it NC4 writing capability?
As part of such an addition (including & using the JHI & JHI5
libraries), would you also consider refactoring the current HDF read
support to utilize the JNI libraries?
Best,
Chris
