My understanding from the documentation was that prudent was only
relevant when multiple JVM's were writing to the same log. I have
only one. I also read that it's use (although sometimes a
necessity) incurs a 3X drop in speed.<br>

Sorry, I skipped the class loader part of the problem. In any
case, you should really enable prudent mode if you don't want to
have garbage in the shared log file.

Ceki,
<br>
<br>
It looks like this will only work if each application loads it's
own
<br>
copy of the logback classes. If so, this is not the case. Like I
said in
<br>
my original post, we have to place them at the highest level
classloader
<br>
(Tomcat's lib) so there's only one.

There are two applications running under one Tomcat instance

Tomcat also logs via the same file and configuration.

Yes, I read the link in the error but there was nothing
applicable to my
<br>
specific configuration/scenario.
<br>
<br>
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,
<br>
this does not mean that your log files are not being clobbered
under
<br>
Linux. You should probably enable prudent mode [1].
<br>
<br>
It seems that you are ignoring my remarks about setting the
context
<br>
name within the config file. It's OK as ContextJNDISelector
provides
<br>
an alternative solution although ContextJNDISelector is an
overkill if
<br>
you are going to share the same configuration file.

Which applications write to
apache-tomcat-6.0.24\logs\debug.log? Does
<br>
Tomcat write there too?
<br>
<br>
Did you know that you can specify the context name in the
logback
<br>
configuration file? You can also have a configuraion file
per
<br>
application which than share a configuration file via
inclusion.
<br>
<br>
Here is an example:
<br>
<br>
For application A:
<br>
<br>
<configuration>
<br>
<statusListener
<br>
class="ch.qos.logback.core.status.OnConsoleStatusListener"
/>
<br>
<contextName>appA</contextName>
<br>
<include file="c:/foo/shared-logback.xml"/>
<br>
</configuration>
<br>
<br>
For application B:
<br>
<br>
<configuration>
<br>
<statusListener
<br>
class="ch.qos.logback.core.status.OnConsoleStatusListener"
/>
<br>
<contextName>appB</contextName>
<br>
<include file="c:/foo/shared-logback.xml"/>
<br>
</configuration>
<br>
<br>
shared-logback.xml
<br>
<br>
<included>
<br>
<appender name="FILE"
<br>
class="ch.qos.logback.core.rolling.RollingFileAppender">
<br>
<file>${catalina.home}/logs/debug.log</file>
<br>
<br>
<rollingPolicy ....
<br>
</appender>
<br>
<br>
<root level="DEBUG">
<br>
<appender-ref ref="FILE" />
<br>
</root>
<br>
</included>
