Dear all,

I'm trying to power my org with the ditaa block generator, so I downloaded
the jar file, and put it in ~/.emacs.d/org/var/ditaa0_9.jar. Then I include
"(setq org-ditaa-jar-path "~/.emacs.d/org/var/ditaa0_9.jar")" in my .emacs.

However it seems not work well, I do get some results like
blue-a-lot-of-random-digi.png in the exported html, but no picture. So I
went to check the *Message*, finding "Unable to access jarfile
~/.emacs.d/org/var/ditaa0_9.jar". Could not figure out why, does anybody
have some idea?

All the best,

Chao

Check that the file's permissions allows reading for all.

I had a similar problem a while back due to my running emacs under 
Cygwin while JRE is actually a native Windows app.  Thus, the Windows 
JRE doesn't understand the jarfile path.  I had to hack 
org-exp-blocks.el to use cygwin-path-to-windows in a few places.  Of 
course, my issue could be completely unrelated, but without more 
information about your setup we're all flying blind.

FYI:

There's a ditaa.jar distributed with org-mode in the contrib/scripts
directory.
