Problem using AbstractLogEnabled

I have a class that extends AbstractLogEnabled

public class ActionRunner
    extends AbstractLogEnabled
    implements Runnable {
}


bur when I attempt to use getLogger() it always returns an NPE. Is there any
initialization that is required before I can use the logger feature.


cheers

Yes, that's by design. The container is responsible for setting the
logger on its child as the first thing after instantiation by calling
enableLogging(Logger logger). See "Developing with Avalon" for the
complete lifecycle. Other keywords: Inversion of Control.
