use both programmatic and file configuration

Hi,

I'd like to provide a way to add loggers/appenders to
log4j whereas I have already configured it
programmaticaly with a default, unremoveable appender.

That is, I have a ConsoleAppender or FileAppender
(defined in code) and I'd like to allow the user to
add an SMTPAppender if he wants to.

How could I archieve this ?
Does the fact that the user provides a log4j
configuration file annihilate the programmatic part ?

thanks,
Ionel

Re: use both programmatic and file configuration

Ionel,

If your programmatically configured appender is attached to a logger, say 
x, and your user's SMTPAppender (configured using a script) is attached to 
logger y, where x != y, then user's configuration will not override the 
programmatic configration. However, if x=y then, your programmatically 
configured appender will be closed before SMTPAppender is attached to logger x.

Does that help?
