I am not an expert on graphviz, unfortunately, but I can tell with confidence that the service at http://www.w3.org/RDF/Validator/ uses a much more recent version of graphviz (2.8-3). Why do you think version 1.7.4 would solve the problem? Looking quickly at the code for ARPServlet.java http://dev.w3.org/java/classes/org/w3c/rdf/examples/ARPServlet.java the error you mention happens when running graphviz (as a standalone script) fails. A way to fix the issue would be to first check that the "dot" script works. > GRAPH_VIZ_FONT_DIR = /Volumes/Macintosh_HD_2/graphviz-2.20.3/graphs > (I can not find the dir of Fonts) Given what you wrote, I strongly suspect that your graphviz config is problematic. In particular, if you do not have a repository of fonts, maybe trying to not set that variable at all would be betther than setting it to a wrong path? The graphviz project has a mailing-list and documentation online, hopefully they should be of interest. Hope this helps, -- olivier
