Hi Scott,

I presume you have already read the link provided in the error:

   http://logback.qos.ch/codes.html#renamingError

Which applications write to apache-tomcat-6.0.24\logs\debug.log? Does Tomcat write there too?

Did you know that you can specify the context name in the logback configuration file? You can also have a configuraion file per application which than share a configuration file via inclusion.

Here is an example:

For application A:

<configuration>
  <statusListener
     class="ch.qos.logback.core.status.OnConsoleStatusListener" />
  <contextName>appA</contextName>
  <include file="c:/foo/shared-logback.xml"/>
</configuration>

For application B:

<configuration>
  <statusListener
     class="ch.qos.logback.core.status.OnConsoleStatusListener" />
  <contextName>appB</contextName>
  <include file="c:/foo/shared-logback.xml"/>
</configuration>

shared-logback.xml

<included>
  <appender name="FILE"
            class="ch.qos.logback.core.rolling.RollingFileAppender">
     <file>${catalina.home}/logs/debug.log</file>

     <rollingPolicy ....
 </appender>

  <root level="DEBUG">
   <appender-ref ref="FILE" />
  </root>
</included>

HTH,
