Re: Setting up log4j.xml

2006-12-05 Thread Bender Heri 
Log events which are sent to a specialized Logger (=not Root Logger) will by 
default climb up the logger hierarchy until the root logger and serve every 
appender of every logger found on its way. Your example: a log event sent to 
logger named loggingexample.Main arrieves to this logger, does not find an 
appender, looks up the next upper logger in hierarchy, finds the root logger 
with level DEBUG and serves its appender A1.

To achieve what you want, supply the logger loggingexample.Main with the 
appender-ref A1 and set the logger's property additivity=false. This will 
prevent the log event to climb further up the hierarchy.

logger name=loggingexample.Main additivity=false
 level value=error/
 appender-ref ref=A1 /
 /logger

This is my current xml configuration..somehow the class Main still prints
out those levels that are below error.

log4j:configuration xmlns:log4j=http://jakarta.apache.org/log4j/;

It shouldn't. Maybe you are not fetching the logger correctly. How you 
instantiate the logger in the Main class? It should be:

Logger.getLogger( loggingexample.Main )

or

Logger.getLogger( this.getClass() )

The latter is only valid if loggingexample.Main is exactly the FQCN of MAIN 
(normally there is a a toplevel domain in front, i.e. 
com.loggingexample.Main).

Try it with annother appender (maybe FileAppender) for the 
loggingexample.Main-Logger. So you can see which logger outputs the event.

Bender,

You are correct in your latest analysis, but incorrect on your original
analysis.  Chuanjiang's original XML file was just fine and the fact that he
increased the level to error should have made it so that only ERROR messages
would print to the A1 appender for that specific logger, while all other
loggers would print to the debug level.

There are a couple possibilities why this might not be working.

1.  As you mentioned, the logger name might not exactly match that being
referenced in the log4j.xml file

2.  Another config file is being used instead of this one.


Note that the approach I would generally take to configuration is to set the
root logger to some higher level such as warn and then selectively set
loggers to debug where I truly want to see debug output.

Appreciate all help,

Indeed the logger name is does not match the one being referenced in the
log4j.xml file.

instead of
Logger mylogger = Logger.getLogger(Main );

should be
Logger mylogger = Logger.getLogger(loggingexample.Main );

Should have check throughly.
Thanks guys
