see the code below

			

			import com.foo.Bar;
			

			

			// Import log4j classes.
			

			import org.apache.log4j.Logger;
			

			import org.apache.log4j.BasicConfigurator;
			

			

			public class MyApp {
			

			

			// Define a static logger variable so that it references the
			

			// Logger instance named "MyApp".
			

			static Logger logger = Logger.getLogger(MyApp.class);
			

			

			public static void main(String[] args) {
			

			

			// Set up a simple configuration that logs on the console.
			

			BasicConfigurator.configure();
			

			

			logger.info("Entering application.");
			

			Bar bar = new Bar();
			

			bar.doIt();
			

			logger.info("Exiting application.");
			

			}
			

			}
			

		

------

			

			

			package com.foo;
			

			import org.apache.log4j.Logger;
			

			

			public class Bar {
			

			static Logger logger = Logger.getLogger(Bar.class);
			

			

			public void doIt() {
			

			logger.debug("Did it again!");
			

			}
			

			}
			

			

			

		

Here the the "MyApp" is only configured with basic configurator and "Bar" is not configured.Can you explain about it.

thanks
