Summary
Freshly-installed (via apt-get) Tomcat on a freshly-installed Ubuntu 8.04 LTS 64-bit works, but doesn't (seem to) log anything. See also "What I've Tried" and "Closing In On It" below.
More Detail
Because the package maintainers have done a HUGE amount of the work, getting basic things working has been a fairly straightfoward matter of running apt-get and pointing Tomcat at the right JDK. And it works. But it doesn't appear to log anything.
As far as I can tell, the logging infrastructure is controlled via logging.properties files (since this is Tomcat 5.5, not Tomcat 5.0), including a central one (which you can override per web app) at /etc/tomcat55/logging.properties (/etc/tomcat55 is symlinked as /var/lib/tomcat55/conf). I'm not overriding it, and I can't see why I'm not seeing something. Here's the file:

The only change I've made is:
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].level = DEBUG
...which was set to INFO like all the others, but I wanted to get it to log something, so I upped it to DEBUG. Naturally I've restarted Tomcat.
I can compile and view a JSP, so again Tomcat is working, but /var/lib/tomcat5.5/logs is stubbornly empty. Even if I force an error by having an invalid JSP or some such, I'm getting nothing.
What I've Tried
- I've been through the steps listed in the Tomcat FAQ for ensuring that the distro hasn't messed things up (they hadn't).
- I've gone looking for a
logsdirectory elsewhere in case it's not/var/lib/tomcat5.5/logs(although that was created by the install). - Naturally I've restarted Tomcat after making any changes.
One thing I haven't done is to chown everything to be owned by the tomcat55 user that the install created. logs is owned by tomcat55, but a number of the other directories and files are owned by root, though they're world-readable. I haven't done this because (hangs head) I can't quite figure out how to fully back-up the existing tree so I can readily undo the change. The blasted tree has absolute symlinks interweaving /etc/tomcat55, /var/lib/tomcat55, and /usr/share/tomcat55 that I know of. I could tar up each of those, but I don't know for certain I'm not missing something.
EDIT:
Closing In On It
Okay, so I've found that it's writing console-style stuff to /var/log/daemon.log. Whew! At least that gives me a place to start. And it's issuing complaints like:
jsvc.exec[18819]: Can't load log handler "2localhost.org.apache.juli.FileHandler"
jsvc.exec[18819]: java.lang.ClassNotFoundException: 2localhost.org.apache.juli.FileHandler
And I'm not surprised, 2localhost.org.apache.juli.FileHandler isn't a valid class name (packages can't start with digits!). So I'm suspecting that the default logging.properties file is...not good. Will report back.
