Are you looking for something like this:

Logger logger = Logger.getLogger("org.myapp");
//set logging level to ERROR
logger.setLevel(Level.ERROR);

Well i need to do what you mentioned dynamically. That wont work for me. You must have noticed that each time you make a change to the configuration file, you have to restart your application. This can be a little bit cumbersome. I was wondering if there is a dyanmic way of changing the logging levels without restaring the server .

Using PropertyConfigurator.ConfigureAndWatch() you can enable log4j to watch any changes to the configuration file and apply those changes to the logging at runtime without any restart of the application.

Hope that helps
