  I have embedded Kaffe in Amaya Web browser/editor of the W3C
you can fetch the code from Sunsite mirrors:


The glue code is in the directory javalib, look at kaffeine.c,
a stub generator for Java/Kaffe->C is available in tools/javastubs
it produces the stubs by scanning C includes files for constants,
enums, and functions signatures.

(note that you also need the Thot library sources to build Amaya-java
 contact me it you really want to rebuild the Java version, not just
 looking at the code)

  2/ should be clearly possible since that's what Kaffe engine does !

  1/ looks more like the Java compiler jobs, you could grab existing
     free replacement of javac written in C and embedd them too, should
     be possible but kaffe won't provide it directly I guess.
