AFAIK there is no easy way to get the mail jars in the geronimo  
startup classloader, although you might try lib/endorsed.

I don't know anything about the internal structure of log4j but I  
wonder, if there is a way to register an appender in code, if the  
simplest and least invasive solution would be to write a geronimo  
gbean to register the appender directly?  You'd lose log output up to  
the point where that gbean started.
