I removed the old Java version from %PATH%, and now java -version gives
the correct version (1.6.0_21).

I can use ditaa on the command line:

H:\org\test>java -jar ditaa.jar ditaa_test.txt

DiTAA version 0.8, Copyright (C) 2004--2009  Efstathios Sideris

Running with options:
Reading file: ditaa_test.txt
Locale: en_US
Dialog.bold
Rendering to file: ditaa_test_4.png
Done in 0sec

But when I try to run the same ditaa code from within org-mode using
babel, I get error messages:

java.lang.UnsupportedClassVersionError:

Here's my source:

#+begin_src ditaa :file folder_structure.png :cmdline -r -s 0.8

        +--- MS/

#+end_src

#+results:
[[file:folder_structure.png]]


And my babel set up from my .emacs:

(setq org-ditaa-jar-path "~/.emacs.d/org-mode/contrib/scripts/ditaa.jar")

(add-hook 'org-babel-after-execute-hook 'org-display-inline-images)

(org-babel-do-load-languages
 'org-babel-load-languages
 '((emacs-lisp . t)
   (ditaa . t)))

Am I still missing something here?

Thanks and Cheers
