problem commons logging / log4j setup open webapp tomcat 6

i have problem wih logging setup apring webapp deployed underneath tomcat 6.

the webapp uses commons-logging api, runtime log4j should used. record record combined nonetheless stays lifeless - record entries occur.

the setup following:

web-inf/web.xml:

 <context-param>
    <param-name>log4jconfiglocation</param-name>
    <param-value>/web-inf/log4j.xml</param-value>
  </context-param>
  <listener>
    <listener-class>org.springframework.web.util.log4jconfiglistener</listener-class>
  </listener>

web-inf/classes/commons-logging.properties:

org.apache.commons.logging.log=org.apache.commons.logging.impl.log4jlogger

web-inf/log4j.xml:

<log4j:configuration xmlns:log4j='http://jakarta.apache.org/log4j/'>

  <appender name="console" class="org.apache.log4j.consoleappender">
    ...
  </appender>
  <appender name="file" class="org.apache.log4j.rollingfileappender">
    <param name="file" value="${catalina.home}/logs/my.log"/>
    ...
  </appender>

  <logger name="my.package">
    <level value="info"/>
  </logger>

  <root>
    <level value="error"/>
    <appender-ref ref="console"/>
    <appender-ref ref="file"/>
  </root>
</log4j:configuration>

the record logs/my.log created, nonetheless logs appear. info logs tomcat console, nonetheless plans settlement configured.

the commons-logging-1.1.1.jar log4j-1.2.14.jar enclosed web-inf/lib. any thought wrong here?
