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,

I just discovered that log rotation fails on Windows if using
ContextJNDISelector. I've tried both FixedWindowRollingPolicy and
TimeBasedRollingPolicy with the same outcome. If I disable JNDI, I lose
the contextName but rotation occurs as expected.
Here's the error I get:

And here is my logback.xml file:

The logback and slf4j resources must be loaded by the servlet container
classloader (multiple reasons) and this is also desirable as we want to
funnel all logging into a single file however, we also need to know
which application generated the call - er go our use of JNDI (MDC
wouldn't work).
By the way, this is a Windows-only issue. Works splendidly on Linux.
Thanks.
