extending log4j Logger class? How to?

[Ian Huynh <ia...@hubspan.com>]

I would like to debug more than just a string so would it make sense to extend the Log4J Logger?

eg.  let say, i'd like to have the following interface
    
         Logger.debug( String, byte[], Document, Throwable)

I can certainly use a wrapper pattern (see below) but would have to make massive changes to my code.  

public class MyLogger {
   public MyLogger (Logger log4jLogger) {}
}
   
So the alternative is,  I tried to extend the Logger Class but is unsure how to get the LoggerFactory to return MyLogger instead of Logger class.

Is there an easier way to accomplish this ?

Thanks.

if you can pack all of the data you would like to log into one wrapper 
object, I would look into using an ObjectRenderer to do what you suggest. i.e.,

    logger.debug(new MyLogObject(String,byte[], Document), Throwable);

You would then provide an ObjectRenderer that undertands how to handle a 
MyLogObject...etc...
