I have a snippset that I use like gazillion times in Linux that absolutely have no problem. But on windows it fails.
log4j: Using URL [file:/C:/Users/vbb/Documents/NetBeansProjects/MailNotification/./log4j.properties] for automatic log4j configuration.
log4j: Reading configuration from URL file:/C:/Users/vbb/Documents/NetBeansProjects/MailNotification/./log4j.properties
log4j: Could not find root logger information. Is this OK?
log4j: Finished configuring.
log4j:WARN No appenders could be found for logger (com.mycompany.mailnotification.Main).
log4j:WARN Please initialize the log4j system properly.
The code like this:
System.setProperty("log4j.configuration", new File(".", File.separatorChar + "log4j.properties").toURL().toString());
final Logger logger = Logger.getLogger(Main.class);
logger.debug("Program start!");
Here is the properties file which is placed everywhere from src\main\resources, src\test\resources... In linux, I just place it in project folder.
# Root logger option
log4j.rootLogger=DEBUG, stdout, file
