Question

How I do to the logging go to the Windows console (that black thing, CMD, COMMAND)?
I’m trying with ConsoleAppender, but I don’t if I doing it right.

private static ConsoleAppender appender = new ConsoleAppender(new PatternLayout());
private Logger database;

Log() {
    BasicConfigurator.configure();
    database = Logger.getLogger("DATABASE");
    database.addAppender(appender);
}

EDIT:
first: this code is a sample, it is bigger than this
second: on the console of Netbeans works perfectly.

You need to setup all the appenders before logging information. Usually the setting up of log4j (including adding appenders) is done during startup of your application.

You should read the documentation here before trying anything more.
