Ok thanks. As suggested I applied warn to the root level logger. I agree it makes sense to do so.

Thanks

Log4j-1.3 uses itself for logging.  You set the root logger to "debug".  Given
that, any library that uses log4j or commons-logging wrapping Log4j will log to
the debug level.  Try adding...

    <logger name="org.apache.log4j">
        <level value="WARN"/>
    </logger>

That said, it probably makes more sense to apply "warn" to the root logger and
specify "debug" to any specific logger [hierarchy] for which you want debuging
turned on.  Otherwise, you are going to have to individually turn off debugging
for every library that you don't want debug output.  It's much more manageable
to turn debugging on for the specific loggers from which you actually want to
see debugging output than vice-versa.
