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?
