Hi Ghislain,

As I understand you'll need two binary packages for the Java bindings:

* libsimpleitk-java (arch: all), with simpleitk-1.0.1.jar installed in
/usr/share/java and a versionless symlink in the same directory (I
suggest using a javahelper debian/*.jlibs file to handle this operation).

Ack, I'll look into javahelper. I have only dealt with maven-based packaging so far.

* libsimpleitk-jni (arch: any), with libSimpleITKJava.so in a multiarch
path (for example /usr/lib/x86_64-linux-gnu/jni/)

Ack.

You'll have to ensure the .so file isn't included in the jar, this may
require some tweaking of the library loading code.

I am not sure what you mean here, though that might be because of my personal ignorance of how JNI works. Could you be a bit more explicit please?

I have also looked at similar packages using swig to generate Java bindings. src:vtk6 [1] does provide separate java and jni packages as you are proposing, but src:gdcm [2] does not. I have got to say, I am a bit confused.

[1] https://packages.debian.org/source/sid/vtk6
[2] https://packages.debian.org/source/sid/gdcm

Cheers,
Ghis
