Using Log4J with an existing java.util.logging appender
Dear all,
Given an application server with his logging (based on jdk logging) I would need my application which uses log4j to log some information on the application server appender.
Is that feasible?
Thank you very much

AW: Using Log4J with an existing java.util.logging appender
Posted by Stadelmann Josef <jo...@axa-winterthur.ch>.
Hi Edmondo,
My understanding is that appender is a log4j concept! isn't it?
So your application (maybe an axis2 service or a different web-apps) likes to uses log4j-loggers and log4j-appenders for logging,
then your log4j-loggers will send to one or more agreed configured log4j-appender (the destination).
As your AS does not know the appender-concept, how can it log via a log4j-logger to the attached log4j-appender? It can't!
Otherwise: Your log4j.properties mast have at least one root-logger defined which gets all what lower level log4j-loggers by use of log4j-additivity=false are not keeping by themselves, but allow to propagate to the log4j-root-logger, which is often a console. Now if this consol has the same physical device attached as the jdk-root-logger, what you will see is 1. the logging events from the AS loggers printed/formatted in a JDK way, and 2. mixed up with log records from your apps sending to a log4j-logger connected to a log4j-consol-appender.
You can stay with that MIX at the root logger level, or
you can make your apps using JDK loggers as well, or
you can configure your AS to make use of the log4j system.
We use the latest for flexibility,
but even then, the AS will start with its built in logger capability
unless it reads itself its own log4j configuration properties, when it starts to use log4j

I'm not sure this will work, but may be worth exploring: use the slf4j
log4j adapter (so calls to log4j logging calls go to slf4j), and configure
slf4j to log to j.u.l.
