Anyone know what this is happening? I think I know where it is coming from. DomConfigurator#parseAppender() seems to return null, but I'm not sure why?
Note that log4j.jar and log4j-sandbox.jar are in CATALINA_HOME/common/lib and shared/lib respectively (the jars can see each other just fine even in the the separate lib directories). I'm using the ContextJNDISelector to manage logger repositories. The other appenders work just fine. Only if I add an <appender-ref> referencing the named ServletContextLogAppender in the second app being configured (and presumably any additional apps) do I get the stacktrace.

I understand what you mean now -- the explanation was clear, complete, and helpful. It also answered my self-asked question which was why I wasn't using this approach anymore -- too tied to the server for my taste ;)
