Creating logfiles for different services (Log4j)

[Gagan Grover]

I have an application in which i am creating 3 services and i have the following log4j.properties file for the application.

log4j.rootLogger=DEBUG, Stdout

log4j.logger.com.ql2.etl=DEBUG, EtlFileAppender
log4j.logger.com.ql2.runcompletion=DEBUG, RCFileAppender
log4j.logger.com.ql2.runarchive=DEBUG, RAFileAppender

Now, whenever i run these services from their main class all the service log files get generated but i want only the log file for that service should get generated. Can I achieve this thing in the same log4j.properties file or do i need to have separate properties file for each service? Please suggest.

Apparently not configurable. But you could write your own custom appender (extending the existing ones) to have the behaviour you desire.
