</log4j:configuration>

The standard behaviour for log4j appenders is that they log all messages at their threshold level or higher, i.e. an appender with threshold INFO will log INFO, WARN, ERROR and FATAL messages but not DEBUG. If you want to log only INFO messages but not WARN and above then you need to use a LevelMatchFilter.
You will also need to set your root logger priority to DEBUG, otherwise it will only send ERROR and FATAL messages to its appenders and your DEBUG and INFO files will be empty.

Spring WebFlow Project. I can't stop log4j from printing debug statements

I am working on a Spring WebFlow Project. I can't stop log4j from printing debug statements. can someone please tell me how to get it to stop putting debug statments on the console and log.
I see this warn as my server starts:
log4j:WARN Continuable parsing error 42 and column 11
log4j:WARN The content of element type "logger" must match "(level?,appender-ref*)".

This is just a log4j issue. It appears that <priority> is not a valid sub-element of the logger element <root>. Rather, you should have <level> instead.

Your root looger defines debug logging for all components. You should change it to warn (so you still see warnings) and add an extra logger for your own components:
<logger name="com.xxx.mycomponent">
<level value="trace"/>
<!-- appenders ... -->
</logger>
<root>
<priority value="warn" />
<appender-ref ref="console" />
<appender-ref ref="dailyrollinglogfile" />
</root>

Simply turn off the logging for the package you don't want to see in your logs...

<priority value="OFF"/>
