Create LogFactory/Log for Log4j and use commons.logging

[Vernier, Dominique (DVernier)]

Hi,

I would like to use commons.logging with Log4j has underlying logging
system. I know that commos.logging will use Log4j if it found in the
class path, but I would like to create my own LogFactory and use:

import org.apache.commons.logging.Log; 

import org.apache.commons.logging.LogFactory;

        private static Log logger = LogFactory.getLog(Test.class);

I know also that by setting system property
-Dorg.apache.commons.logging.Log=... we can define the Log class used by
commons.logging.LogFactory to instanciate the Logger.

Then based on the sample of MyLoggerFactory and MyLogger, I create my
own factory and logger. I implement the commons.logging.Log in the
MyLogger, but when I used it I have a nullpointer on the repository.

Do you have any idea or examples on which I can relie?

Thx
Dominique
