Logback access in DM Server?

[blahb]

I am trying to migrate a Tomcat app to DM Server 2.0.2.RELEASE. We currently use logback access logging as described here (http://logback.qos.ch/access.html).

Does anyone have any knowledge/experience with integrating logback access into DM Server?

The most problematic looking step to me initially appears to be the first among the draft steps I've created below:

1) logback-core-0.9.x.jar and logback-access-0.9.x.jar are typically placed in $TOMCAT_HOME/server/lib/. How do we do the comparable in DM Server to make them available to the tomcat bundle? A fragment (http://forum.springsource.org/showthread.php?t=90578)?

2) Add valve to tomcat config:

<Valve className="ch.qos.logback.access.tomcat.LogbackValve"
    filename="/opt/springsource-dm/config/logback-access.xml">

within an <Engine> or <Host> element.

3) Create /opt/springsource-dm/config/logback-access.xml file, such as:

<configuration>

  <appender name="FILE"
    class="ch.qos.logback.core.rolling.RollingFileAppender">
    <File>/opt/springsource-dm/serviceability/logs/access.log</File>
    <rollingPolicy
      class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
      <FileNamePattern>access.%d{yyyy-MM-dd}.log.zip</FileNamePattern>
    </rollingPolicy>
    <layout class="ch.qos.logback.access.PatternLayout">
      <Pattern>combined</Pattern>
    </layout>
  </appender>

  <appender-ref ref="FILE" />

</configuration>
