I'm running 12.0.22 currently, with 12.0.23 scheduled to be installed
automatically tonight on dev systems. I went ahead and pushed it out
manually to one of them and as far as I can tell my access logs are
still working fine.


In /var/lib/jetty/resources/logback.xml I've got:

  <appender name="jetty-access"
class="ch.qos.logback.core.rolling.RollingFileAppender">                     
    <file>/var/log/jetty/access.log</file>
    <rollingPolicy
class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">                               
      <fileNamePattern>${jetty.base}/logs/access-%d{yyyy-MM-dd}.log.gz</fileNamePattern>                     
      <maxHistory>90</maxHistory>
    </rollingPolicy>
    <encoder>
      <pattern>%msg%n</pattern>
    </encoder>
  </appender>

  <logger name="org.eclipse.jetty.server.RequestLog" level="INFO"
additivity="false">
    <appender-ref ref="jetty-access" />
  </logger>

Then in /var/lib/jetty/etc/jetty-requestlog.xml I've got:

<Configure id="Server" class="org.eclipse.jetty.server.Server">                                              

  <!-- =========================================================== -->
  <!-- Configure Request Log for Server                            -->
  <!-- Use RequestLogHandler for a context specific RequestLog     -->
  <!-- =========================================================== -->
  <Set name="RequestLog">
    <New id="RequestLog"
class="org.eclipse.jetty.server.CustomRequestLog">
      <!-- Writer -->
      <Arg>
        <New class="org.eclipse.jetty.server.Slf4jRequestLogWriter" />
      </Arg>

      <!-- Format String -->
      <Arg>
        <Property name="jetty.requestlog.formatString"
deprecated="jetty.customrequestlog.formatString">
          <Default>
            <Get class="org.eclipse.jetty.server.CustomRequestLog"
name="EXTENDED_NCSA_FORMAT"/>
          </Default>
        </Property>
      </Arg>
    </New>
  </Set>
</Configure>


Finally in /var/lib/jetty/start.d/logging-logback.ini I have:

--modules=logging-logback

slf4j.version=system
logback.version=system

# Route request logging through standard logging API
etc/jetty-requestlog.xml


The logback jar used by the idp is version 1.5.6, but the one being used
by jetty itself is 1.5.3...
