I think 2) is a real problem. Choice 2a) opens a can of worms with native compilation of a library with just the right set of compiler/linker options to allow it to be opened by Runtime.getRuntime().loadLibrary(name). I've done it several times on Unix and Linux systems with autoconf/automake/libtool but this is really a pain. I also don't know how to do that on Windows or other systems. Choice 2b) raises different issues: f2j is distributed under a modified GPL license (i.e. GPL with the addition of the BSD advertising clause, something I have never seen before). It is announced in sourceforge as being published under a BSD license, but the LICENSE file in both f2j 08. and f2j 0.8.1 are GPL with BSD clause ... The underlying javab tool is also freely available only for education, research and non-profit purposes. We clearly can redistribute neither f2j itself nor javaB due to these licensex and so would have to distribute only the already compiled jar files. I'm reluctant to distribute binary only blobs in our distribution (and if I remember correctly, Phil also didn't like this idea). I don't know of any other fortran to java conversion tools.
