Sorry, didn't see the config link. delete


they are useless.

server.xml: not readable (Forbidden)


JkLogLevel emerg: better use "info", and when debugging "debug" but not
for high load production.

JkLogFile: once your setup works, consider including rotatelogs.

manager-JkMounts: Those are in a virtual host named "localhost": I would
guess your requests to the manager webapp are served by another virtual
server or the global server. Those won't see the JkMounts defined in
"localhost". The above cited log message "from 0 maps" also tells us,
that the virtual server handling the requests din't find any JkMounts.

I would replace the whole localhost:/manager block by

JkMount /manager|/* ajp13


JkLogStampFormat "[%a %b %d %H:%M:%S %Y] ": Remove it or have a look at
the docomentation to include milliseconds.

JkAutoAlias /usr/share/apache-tomcat-6.0.18/webapps: do you really want
