Java Logigng, Custom FileHandler level problem.

Question

Dears,
I would like to use java builin logigng facility, but the problem is that it is not providing the facility of daily file rolling in FIleHandler as log4J is providing the facility in DailyRollingFileAppender
I found the custom File handler form the following thread:
http://forum.java.sun.com/thread.jspa?forumID=256&threadID=421131
But the problem is that now I cannot able to change the logger level at runtime using
Logger.setLevel() or using JMX Mbeans exposed by java.util.logging.
I was able to change the loglevel when I was using java.util.logging.FileHandler
I found that level setting is done at Logger also at handler level.
So how can I handle this?
I want to log file on daily basis + also want to provide facility to change level using JMX.
thanks.

Okay, I figured out my problem, but I'm not sure how much it's going to help you. My problem was the same as yours (I just didn't know it). It had nothing to do with multiple threads, but had to do with the fact that I was reinitializing the LogManager multiple times (I have the init in a static class that multiple classes use and didn't realize the number of times it was getting called).
Now, I do have a possible suggestion for changing handlers, if you're okay doing it inside code (instead of using a config file). Technically, you could creat your own config file and change some stuff.
Anyway, here's what I do to change handlers:
private static Logger logger = Logger.getLogger(Archive.class.getName());
(in function)
try {
    logger.removeHandler(reportArchiveHandler);
} catch (NullPointerException e) {
    // ignore
reportArchiveHandler = new FileHandler(this.getCurrentLogDir() + "/log.txt", 50000, 1, true);
reportArchiveHandler.setLevel(Level.INFO);
reportArchiveHandler.setFormatter(new AuditFormatter());
logger.addHandler(reportArchiveHandler);
LogManager.getLogManager().addLogger(logger);
}That changes the handler and doesn't create any new files. The only problem is you can't just read a new config file.
Hope that helps a little,
Mike
