Category vs. Logger configuration

Hi!

I am co-working on a large project. We are in a transition from using
Category to Logger. During this transition, we will have uses of both
Category and Logger.

I want the configuration property file to configure both. Shall I configure
like this

  # Attach appender A1 to root. Set root priority to Prority.DEBUG.
  log4j.rootCategory=DEBUG, stdout, A1
  ...
  (in which case I think instances of the base class Category gets
configured, and therefore also instances of its subclass Logger)

or like this

  # Attach appender A1 to root. Set root priority to Prority.DEBUG.
  log4j.rootLogger=INFO, stdout, A1
  ...
  (in which case I think only instances of the subclass Logger gets
configured, but not instances its superclass Category)

???

Kindest regards

Niels K. Henriksen

The produced references are actually Logger instances. Log4j 1.2 never
produces Category instances, only Logger instances.
