Hi Thomas and Marcelo,

Did not know that. Not using it myself.

Yes, you can easily add new languages. I did that for AWK:

--8<---------------cut here---------------start------------->8---
;; Org-babel needs to be told to recognize awk source code blocks and
;; how they should be tangled, which can be accomplished with the
;; following:
(org-babel-add-interpreter "awk")
(add-to-list 'org-babel-tangle-langs '("awk" "awk"))
--8<---------------cut here---------------end--------------->8---

I guess replacing awk by java would make it. Untested, though, as I don't use
it.

I guess this is the best thing to do, yes. Thanks for your comment (and
support), Thomas!

Best regards,
