I have a bad feeling no one else has tried this :-(

I'd probably start by talking with the Java-GNOME bindings developer(s)
and finding out if they have a tool or some docs on how to write Java
bindings for gtk-style libraries. I'm sure they must. The Mono/C#
bindings are all auto-generated (with only a few minor tweaks).

I guess the first step is binding GMime to Java. After that, the best
place to look for an example on how to use GMime's parser is in the
source tarball under examples/basic-example.c or
examples/imap-example.c, both of which will show you how to loop over
the MIME parts in a GMimeMessage - what you decide is the "body" is
really up to you, but there is some simplistic logic here:

http://git.gnome.org/browse/gmime/tree/gmime/gmime-message.c#n1576

For your convenience, the examples can be found on the web too:

If you have any more questions, feel free to ask.

Good luck on your project,
