How to send messages of a class into one and only to one appender with log4j?

[Zsolt Koppany]

Hi,

How can I store the log messages of "cv.parser_db_log" only to appender
"parser_db_file"? Right now messages sent to "parser_db_file" will be also
stored into "A2" and "A1".

I use log4j-1.2.8.

My configuration:

log4j.rootCategory=DEBUG, A2, A1
...

log4j.category.cv.parser_db_log=INFO,parser_db_file
