True, I think I should've explained my situation more...
We are using commons Fa�ade for logging. So, my ability to interact direct
log4j is pretty limited.

I'm trying to find a good example of a log4j.xml explain me how to-do this.
 
Thanks

Log 4j was designed to do exactly that.

Have you built a hello world program yet?

The constructors will show you how to control logging granularity.

I am new as well. Here's a program I wrote. 

Pay attention to all the object that are necesasry to instanciate the
logger. 

Play with their settings to achieve your desired output control.

I hope that helps.

public class TestLogger {
        static Logger myLogger = Logger.getLogger("TestLogger");
        
        public static void main(String[] args) {
                File myFile = null; 
                FileOutputStream myFileOS = null;
                PatternLayout myLayout = null;
                WriterAppender myAppender = null;
                
                System.out.println("Writing to file...");
                try {
                    myFile = new File("foo.out");
                        myFileOS = new FileOutputStream (myFile);
                }catch (Exception e) {
                        System.out.println(e.toString());
                }
                myLayout = new PatternLayout("%m%n");
                myAppender = new WriterAppender(myLayout, myFileOS);
                myLogger.addAppender(myAppender);
                myLogger.setLevel(Level.DEBUG);
                myLogger.debug("Hello World with a patternLayout");
        }
}
