I'm using JSPWiki 2.6.4 with Tomcat 5.5 and Java 6. The application
seems to work OK, but I'm getting some errors on starting Tomcat. I
suspected it was a permission problem (I'm using Ubuntu 8.04), but it
occurs even if I run Tomcat as root. Can anyone tell me what might be
causing the stacktrace below? (I'm pretty sure that I've run it
plenty
of times before without these kinds of errors.)
TIA,
Terry
