Question

When you log exceptions, does it get stored somewhere in a file? If so, how do I find this file? If not, why do people bother logging exceptions? I saw this example on the net:

DateFormat df = new SimpleDateFormat("dd/MM/yyyy");
        df.setLenient(false);

        try {
            //
            // Try to parsing a wrong date.
            //
            Date date = df.parse("12/30/1990");

            System.out.println("Date = " + date);
        } catch (ParseException e) {
            //
            // Create a Level.SEVERE logging message
            //
            if (logger.isLoggable(Level.SEVERE)) {
                logger.log(Level.SEVERE, "Error parsing date", e);
            }
        }

When I run it, I see the exception printed on my netbeans console, and I have to wonder, is that it, or is there more to this (there has to be)?

Thanks

It all depends of your logging framework configuration. If you decide to use file appenders and that the log level is loggable, in most cases the exception stacktrace will be printed to a file.
