Hi there, two things come to my mind regarding the "standard" Tomcat coming with a Linux distribution:
* Is this Tomcat running with a security manager enabled? JSPWiki isn't running under a security manager (i.e. without further configuration). * Are advanced security modules like SELinux or AppArmor enabled in these environments? If so, it may be that the Tomcat instance needs some further configuration, especially regarding access to additional files like jspwiki.log. Regards Florian
