AccessLogValve

Tomcat makes use of AccessLogValve which creates log that can later be analyzed by standard log analysis tools to track page hit counts, user session activity, and so on.

AccessLogValve is defined in jbossweb-tomcat50.sar\server.xml (available from JBoss3.2.5 and up) or jbossweb-tomcat41.sar\META-INF\ jboss-service.xml (for JBoss3.2.3 and lower)

           <Valve className="org.apache.catalina.valves.AccessLogValve"
               prefix="localhost_access_log." suffix=".log"
               pattern="common" directory="${jboss.server.home.dir}/log" 
               resolveHosts="false" ></Valve>

By default this is commented out.
