Hi Ceki Gülcü,

Thanks for your fast reply.
So the problem is that I'm not using the Logback but the Log4j 1.3 alpha 8
version that also has
JoranConfigurator object.  (author: Curt Arnold, Ceki
I thought I ask you since you've written it and you more likely to reply to
my message from this forum.
I'm looking at the (Log4j 1.3 alpha 8) API and don't see any LoggerContext
object there.
I have at the moment this in my class:

public someConstructor(String className, String propertyFile) {

        //Reads the configuration file.
        if (!configFile.endsWith("xml") || configFile == ""){
            throw new InvalidParameterException("Invalid XML property

        logger = org.apache.log4j.Logger.getLogger(className);
        JoranConfigurator jc = new JoranConfigurator();
        jc.doConfigure(configFile, LogManager.getLoggerRepository());

This will always work even if I pass in my config file
<blah blah blah/>
Nothing will happen, that is, no exception and no log will be printed.
(written etc.)
Any other suggestions?
I know this isn't the log4j forum.....

There's no such thing as LoggerContext or a method
