I'm trying to install openreports, a Tomcat webapp. Tomcat is running fine (runs demos as well as one other open source app I installed). I was able to create openreports.war and get Tomcat to try to start it (via tomcat manager webapp). The war is expanded and deployed. But when Tomca tries to run it, it fails because of inability to write a log file.

Where is it trying to write this log file, and how can I grant it permission to do so? The openreport install docs did not say that I needed to do anything special with permissions.

Edit /etc/init.d/tomcat5 and stop it loading/using the security manager. I used to know how to do it properly, but can't remember now.
