Re: [Geotools-devel] configuration of java logging using a custom property file

[andrea a. <and...@gm...>]

Hi Jody,
in the end I finished up removing all handlers:

        Logger l0 = Logger.getLogger("");
        Handler[] handlers = l0.getHandlers();
        for( Handler handler : handlers ) {
            l0.removeHandler(handler);
        }

The real problem is that this doesn't remove some messages.
Those are related to imageio-ext, not jai (seems to me at least).

Is there any way to get them also to be silent? What is imageio-ext
using for the logging?

Thanks,
Andrea
