Hello Eugen, PlantUML has found Graphviz (the dot program) and then tries to create the file testdottmp42.dot and encounters the permission issue. It may be a java permission error. Just to test quickly, you can try to disable the security manager of Tomcat. I hope this helps Maxime 2012/8/18 Eugen Colesnicov <[email protected]>:
I am trying to configure PlantUML to work with local Graphviz server. My environment - Linux Mint Debian (last stable), MySQL, Tomcat, XWiki 4.1.3. XWiki installed from standart xwiki deb-packages. No any customization on OS or XWiki. Empty base (only installed standart wiki-pages).
According to PlantUML macros installation guide, I installed Graphviz, and deleted path to external graphviz server. Also I added GRAPHVIZ_DOT to system variable (added export GRAPHVIZ_DOT="/usr/bin/dot" to /etc/profile).
But when I opening test page http://localhost:8080/xwiki/bin/view/XWiki/PlantUMLMacro I have got an error: Dot executable is /usr/bin/dot Dot version: dot - graphviz version ... java.io.FileNotDoundExeption: testdottmp42.dot (Permission denied) ...
I checked - dot executable exists in /usr/bin/. Also I checked environment variables with comand env - all is ok, GRAPHVIZ_DOT variable exists and give correct path.
Also, I tried to give full permissions for /usr/bin/ and dot executable - any user/group can read / write / execute it. Also I tried to change tomcat parameters: TOMCAT6_USER=root and TOMCAT6_GROUP=root for the starting tomcat as root (it is not good for security reason but for testing is ok).
As a result - same situation, same error. What is the problem and how I is possible correct it?
Thanks beforehand! Eugen Colesnicov
