I'm using FixedWindowRollingPolicy and the doc says that prudent mode isn't supported with FixedWindowRollingPolicy (http://logback.qos.ch/manual/appenders.html#RollingFileAppender).

So clarify for me...

If I have only one set of classes loaded by the servlet engine (Tomcat)
and only one logback.xml file shared among all applications, how do I
have multiple appenders?

Sorry, you are right. If logback is loaded only once, then each appender
mentioned in the config file will be loaded once. No need for prudent
mode in this case.

Stupid me. ContextJNDISelector will cause logback-classic to be loaded multiple times. If the logback-classic instances share the same config file, then you will have multiple appender instances writing to the same file => prudent mode needs to be enabled.
