Tried to create libcolt-free-java.git (Was: Please help freeing libcolt-java)

Hi Emmanuel,

I tried with my admittedly close to zero Java skills to follow your
advise given in your mail.

I did so using Files-Excluded and created a new tarball.  I think it is
a good idea to provide it as a separate package libcolt-free-java (feel
free to suggest a better name).

I think I've got this.

Not sure what to do here.

I also fetched the files from freehep jaida with the same names and
moved them into place.  I commited this to

   git://anonscm.debian.org/debian-med/libcolt-free-java.git

and you can find the files I fetched from freehep jaida in
debian/freehep-jaida (and the script I used to fetch the files to make
it reproducible what I did).  The freehep files are moved right into
the old place in d/rules.

Unfortunately I'm not as lucky as you since my attempt to build failed
with

    [javac] /tmp/buildd/libcolt-free-java-1.2.0+dfsg/src/hep/aida/IAxis.java:11: error: package hep.aida.jni does not exist
    [javac] import hep.aida.jni.AIDAJNIUtil;

    [javac]     file does not contain class hep.aida.IAxis
    [javac]     Please remove or make sure it appears in the correct subdirectory of the sourcepath.

BUILD FAILED
/tmp/buildd/libcolt-free-java-1.2.0+dfsg/build.xml:156: Compile failed; see the compiler error output for details.

Unfortunately I have no idea what to do next.

I'd be happy to reproduce this if I get some hints how to build
libcolt-free-java.

The question in my other mail where I responded to your mail above was
how we actually should proceed packaging freehep aida/jaida.  I would
need more exact advise how you would obtain the tarball of what really
needs to be packaged.  I fail to understand all the files in their SVN
and how they are organised and what part we will really need.
 
So this boild down to two questions:

  1. Is there any chance to get libcolt-free-java building and working
     with this as a quick and dirty solution

  2. Could any kind soul give a kickstart for freehep aida/jaida
     packaging.  I would try to help finishing it to get a cleaner
     solution than the code copy above.

Kind regards

     Andreas.
