Is there a command line option for setting the default log level in Java

Can I do something along the lines of:

-Djava.util.logging.loglevel=FINE

Obviously that doesn’t work, but you get the idea. Is there anything like that? Or am I forced to create a properties file?

Answer

You can even pass your log Level as a user defined property.

-DmyProp.logLevel=FINE

In your code:

String logLevel = System.getProperties("myProp.logLevel");

But I have the idea that your are looking for a more “built-in” and automatically handled property, right? AFAIK, it doesn’t exist, but maybe I’m wrong.
