Yes, I read the link in the error but there was nothing applicable to my
specific configuration/scenario.

Like I said, it does exactly what we want on Linux but log rotation
fails on Windows. If I disable JNDI, log rotation works but then I lose
context identification (application name) which is likewise critical.

Linux is less picky about renaming files with open handles. However,
this does not mean that your log files are not being clobbered under
Linux. You should probably enable prudent mode [1].

It seems that you are ignoring my remarks about setting the context
name within the config file. It's OK as ContextJNDISelector provides
an alternative solution although ContextJNDISelector is an overkill if
you are going to share the same configuration file.

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,
