[java.util.logging] recording in log file

[Rafael Afonso]

Hello:

I have two classes: One with main() method (caller class) and other not (called class). both record log messages using java.util.loging. Log configuration is done in caller class. I want that log file have messages from caller and called classes. However in log file it is shown only caller messages.
Below, the source codes.
Caller class:

  
package testalog.launcher;
 
import java.io.IOException;
import java.util.Timer;
import java.util.TimerTask;
import java.util.logging.*;
 
 
 
public class LogLauncher {
    private static final Logger log = Logger.getLogger(LogLauncher.class.getName());
    private static final long PERIOD = 15000L;
    
    public static class LauncherTask extends TimerTask {
 
        public void run() {
            LogLauncher launcher = new LogLauncher();
            launcher.execute();
        }
 
    }
    
    public LogLauncher() {
        try {
            FileHandler h = new FileHandler("acao.log"); // log file name
            h.setFormatter(new SimpleFormatter()); // log formatter
            log.addHandler(h);
            log.setUseParentHandlers(true);
        } catch (SecurityException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }        
    }
    
    public void execute() {
        Acao acao = new Acao();
        log.info("Iniciando ..."); // Beginning ...
        acao.execute();
        log.info("Terminando ..."); // Finishing ...
    }
    
    public static void main(String[] args) {
        Timer timer = new Timer();
        timer.schedule(new LauncherTask(), 0, PERIOD);
    }
}

Called class:

  
package testalog.launcher;
 
import java.util.Date;
import java.util.logging.Logger;
 
public class Acao {
    private static final Logger log = Logger.getLogger(Acao.class.getName());
    
    public Acao() {
        log.info("Criando ..."); // Making ...
    }
    
    
    public void execute() {
        log.info("Execute �s" + new Date()); // Execute at ...
    }
    
}

In console I get this:

28/07/2004 15:57:58 testalog.launcher.Acao <init>
INFO: Criando ...
28/07/2004 15:57:58 testalog.launcher.LogLauncher execute
INFO: Iniciando ...
28/07/2004 15:57:58 testalog.launcher.Acao execute
INFO: Execute �sWed Jul 28 15:57:58 GMT-03:00 2004
28/07/2004 15:57:58 testalog.launcher.LogLauncher execute
INFO: Terminando ...
28/07/2004 15:58:13 testalog.launcher.Acao <init>
INFO: Criando ...
28/07/2004 15:58:13 testalog.launcher.LogLauncher execute

28/07/2004 15:58:13 testalog.launcher.Acao execute
INFO: Execute �sWed Jul 28 15:58:13 GMT-03:00 2004
28/07/2004 15:58:13 testalog.launcher.LogLauncher execute
INFO: Terminando ...
...

But in log file It is showed:

28/07/2004 15:57:58 testalog.launcher.LogLauncher execute
INFO: Iniciando ...
28/07/2004 15:57:58 testalog.launcher.LogLauncher execute
INFO: Terminando ...
28/07/2004 15:58:13 testalog.launcher.LogLauncher execute
INFO: Iniciando ...
28/07/2004 15:58:13 testalog.launcher.LogLauncher execute
INFO: Terminando ...

To recapitulate: In console it is showed log messages from caller and called classes, but in log file only caller messages was written. What I need is find a way to record all log messages from called classes in log file.
Suggestions?

Thanks,
