The code is:
try {
ConfigurationSource source = new
ConfigurationSource(new
FileInputStream("Log4jApache.xml"));
Configurator.initialize(null, source);
} catch (IOException e) {
System.err.println("Error while initializing log4j from
file: log4j.xml");
e.printStackTrace();
}
LoggerContext context = (LoggerContext) LogManager.getContext(false);
Appender appender = context.getConfiguration().getAppender("LoggerLog4jDebug");
System.out.println("appender = " + appender);
File xml is:
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="ERROR">
