In addition to Log4j.jar, you have to add commons-logging.jar to common/lib.

With my configuration (when running under the Tomcat Service, not from the 
command line), I get jakarta_service_[DATE].log, stderr_{DATE}.log (though 
nothing ever gets written to it, and stdout_[DATE].log.  The latter is where 
all Tomcat logging goes (as well as out.println() statements).  You are right 
that the host and context logs don't get written with the date included in the 
log file, but the context log will roll with the yesterdays file being renamed 
using the date.  There might be another way to define log files using the 
date, but I don't recall how that is configured.  I don't use 
DailyRollingFileAppender that much.  Maybe someone else can help you out 
there.

Why not deploy log4j.jar with each application?  If each has it's own 
log4j.properteis, then that means you don't intend to share logging 
configuration across applications.  As such, there is no need to put log4j.jar 
in common/lib.  Just put it in WEB-INF/lib of each app.  Note that if you 
don't do this and just have log4j.jar in common/lib, you will have a single 
logger repository that is shared by Tomcat and all your apps.  Any app 
performing a configuration will stomp on all the other apps configuration. 
 Unless you plan to use a repository selector to differentiate logging 
repositories, ALWAYS deploy log4j.jar in WEB-INF/lib of EACH webapp.
