Hi, Ceki:
We set up appenders using static config. file thru PropertyConfigurator.
This configuration is done thru MyLog class. Currently, we have only about
a few appenders. My follow up questions should be:
(1) If we don't close those appenders after each Event, what should we do?
leave them open for the following events?
(2) If we leave those appenders open, at the IO level, when do we close
java.io.Writer, say if it is a file appender.
Thanks very much
- Tony

Please respond to

That doesn't say anything about the way you attach appenders to loggers.
Or?
