Log instances don't have to be created as constants each class, it's just the most common idiom. for AvalonLogger to be of much use, i'd say that the component would need to support setting the Log instance on a per-class basis. > So the short resumee: does not matter for me. good - robert --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
