[roots]

You have some space problem in the code such as space before Appender in second line and space in ISO86 01

Make sure the file for log is accessible, i used a.txt for testing.


This is the fixed code,

Code:

log4j.rootLogger=debug,D
log4j.appender.D=org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.DatePattern='.'yyyy-MM-dd-HH-mm
log4j.appender.D.File=C:/a.txt
log4j.appender.D.layout=org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern=%d{ISO8601} %-5p [%c] - %m%n
log4j.appender.D.Append =true

Sample Java code for the test

Code:

		PropertyConfigurator.configure("config.properties");
		Logger logger = Logger.getLogger(Main.class);
		
		
		while(true){ // Leaved for 5 minutes to see it happen
			logger.info("SOME LOG MESSAGE");
			Thread.sleep(5000); 
		}

Output
