Hi John, The absolute path should work fine, so I guess it is likely to do with file permissions. You will have to consider both the tomcat user/group id as well as the user/group id of the owner of the external rule file.
Also, please check the tomcat security settings. These are by default very restrictive and usually will not allow tomcat hosted web-apps to access files outside of the .../webapps directory. The easiest way to see if this is a problem is to simply disable tomcat security.
