Re: [Quickfixj-users] Unable to route quickfixj.events to log via Log4j (over SLF4J)

[Xiau W. T. <tx...@gm...>]

Indeed that is correct. The logfile is created but permanently empty. I
have:
1. Removed all the default slf4j configuration from session settings
2. Added appender for log4j.logger.quickfixj.errorEvent

Files are created, but empty. I redirect all the screen logs from java
execute line to a dumpfile and I can see all quickfixj events and msg logs
generated without any WARN or ERROR. Turning on additivity will not make a
copy in system_debug.log as well. Version2.1 is the one used.
