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, -- Ceki http://twitter.com/#!/ceki On 03/11/2011 5:47 PM, Scott Dudley wrote:
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:

</configuration>
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.
