Enable/Disable logging programatically.

[I responded to this a minute ago, accidentally prematurely
hit "send", sorry for the spam in my
signature on that one  ]

If you are using Log4j, you can easily change the root
logger level with:

org.apache.log4j.Logger.getRootLogger().setLevel(Level.DEBUG
);

The Level class has constants for log levels or static
methods to get log levels via strings. It
is pretty easy to configure log4j at runtime w/ finer
grained control, see the javadoc.

I tend to typically wire things up with a standard config
file in a default way that I want the
app to run (probably ERROR level) and then adjust things at
runtime as needed.

Hope this helps!
