as far as I know, don't see any way to convert your messages from DEBUG to
LEVEl...
log4J supports filters, but it implies that you develop one filter for
this usage & configure its usage...

I don't think that you're obliged to such a solution...

I guess that you don't want to do this...

May be that the very interesting feature of additivity could save you much
time...
Just define one (or X loggers) for the package source of the interesting
logs, specify addivity to false, reference an appender (file or any other)
then logs should be output in this file.....
and that 's it
