[logback-user] I cant use logback-access

[David Brocard]

Hi

I am new to Tomcat & logback
I'm using tomcat 5.5.25

I can use logback-classic easiy but not logback-access
I have followed the instructions at http://logback.qos.ch/access.html :

1) core and access jar in server/lib folder
2) <Valve className="ch.qos.logback.access.tomcat.LogbackValve"/> in  
th engine tag of the server.xml file
3) logback-access.xml in conf folder :
- <configuration>
  <appender name="STDOUT"
    class="ch.qos.logback.core.ConsoleAppender">
    <layout
      class="ch.qos.logback.access.PatternLayout">
      <Pattern>%h %l %u %user %date "%r" %s %b</Pattern>
    </layout>
  </appender>
  <appender-ref ref="STDOUT" />
</configuration>

but nothing works (no log at all, no error message...)

thanks
