log4j configuration via JVM argument s

Question

What variables do I have to set pass as arguments to the JVM to get log4j to run properly  And by properly I mean not complain and print to the console   Can I see a typical example   Note  I need to avoid creating a log4j properties file in the application

User · Answer

Generally  as long as your log4j properties file is on the classpath  Log4j should just automatically pick it up at JVM startup

Late to the party as since 2015  Log4J 1 x has reached EOL   Log4J 2 x onwards the JVM option should be -Dlog4j configurationFile  lt filename gt     P S   lt filename gt  could be a file relative to the class path without the file  as suggested in the other answers

Relative Path is also ok    java -Dlog4j configuration file    log4j properties  -jar com your-1 0-SNAPSHOT jar   or   java -Dlog4j configuration file    log4j xml  -jar com your-1 0-SNAPSHOT jar

I know this is already answered  but because you said  this isn t exactly what you are looking for  I would like to point out the following alternative   You can also use a configuration class instead of the properties or xml file   -Dlog4j configuratorClass com foo BarConfigurator   See http   logging apache org log4j 1 2 manual html for details

The solution is using of the following JVM argument   -Dlog4j configuration  path to file    If the file is NOT in the classpath  in WEB-INF classes in case of Tomcat  but somewhere on you disk  use file   like  -Dlog4j configuration file C  Users me log4j xml   More information and examples here  http   logging apache org log4j 1 2 manual html

Do you have a log4j configuration file   Just reference it using   -Dlog4j configuration  path to file    where  path to file  should be prefixed with file   Edit  If you are working with log4j2  you need to use  -Dlog4j configurationFile  path to file    Taken from answer https   stackoverflow com a 34001970 552525
