Configure logs without date in the file name

[Ricardo F]

Hello,
I have tomcat 7.0.26 and I see how the /logs folder grow every day with tons of 
logs with the date, like:
catalina.2012-08-20.loghost-manager.2012-08-20.loglocalhost_access_log.2012-08-20.txtlocalhost.2012-08-20.logmanager.2012-08-20.log
How can I remove the date between the name and the file extension for rotate 
this files with logrotate?
I have in the end of server.xml:        <Valve 
className="org.apache.catalina.valves.AccessLogValve" directory="logs"          
     prefix="localhost_access_log." suffix=".txt"               pattern="%h %l 
%u %t &quot;%r&quot; %s %b" />
and in the top of logging.properties:handlers = 
1catalina.org.apache.juli.FileHandler, 2localhost.org.apache.juli.FileHandler, 
3manager.org.apache.juli.FileHandler, 
4host-manager.org.apache.juli.FileHandler, 
java.util.logging.ConsoleHandler.handlers = 
1catalina.org.apache.juli.FileHandler, java.util.logging.ConsoleHandler
Thanks,
