Works fine for me here, so there is probably a syntax error in the lisp
file(s) you load or the lisp code you eval - try using a minimal setup
file as shown below:

GNU Emacs 24.0.50.1 (x86_64-unknown-linux-gnu, GTK+ Version 2.22.0) of 2011-04-13
Org-mode version 7.5 (baseline.273.g889a48)


I do

   emacs -batch --visit=foo.org  -l export.el --funcall org-export-as-html


with export.el containing the following:

--8<---------------cut here---------------start------------->8---
(setq org-confirm-babel-evaluate nil)
(require 'ob-ditaa)
(setq org-babel-temporary-directory "tmp")
(setq org-ditaa-jar-path "/home/nick/elisp/org-mode/contrib/scripts/ditaa.jar")
--8<---------------cut here---------------end--------------->8---


and foo.org containing the following:

--8<---------------cut here---------------start------------->8---

* Export a picture

Need to load ob-ditaa to execute these:

#+begin_src ditaa :file image.png :cmdline -r :exports both
