How to create two log files

I have the following log4j.properties files:

log.path=/var/log/MyApp


log4j.rootLogger=INFO, file

log4j.appender.file = org.apache.log4j.RollingFileAppender
log4j.appender.file.File = MyApp.log
log4j.appender.file.Append = true
log4j.appender.file.MaxFileSize=10MB
log4j.appender.file.MaxBackupIndex=1000
log4j.appender.file.DatePattern = '.'yyy-MM-dd
log4j.appender.file.layout = org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern =%d{yyyy-MM-dd HH:mm:ss} %t/%c{1} [%p] %m%n

When I run MyApp, I obtain MyApp.log file. I wonder if it is possible to set in the code two files for two main class? something like:

object MyApp1 {
  def main(args: Array[String]) = {
    log4j.setName("File" -> "MyApp1.log")
    println("HelloWorld")
  }
}
object MyApp2 {
  def main(args: Array[String]) = {
    log4j.setName("File" -> "MyApp2.log")
    println("HelloWorld")
  }
}

and then, when I will run Myapp1 it will create Myapp1.log and when I will run Myapp2 it will create Myapp2.log

The file name can be parameterized in the log4j.properties file and passed as a JVM argument,

log4j.appender.file = org.apache.log4j.RollingFileAppender
log4j.appender.file.File = ${ApplicationName}.log

Can pass the ApplicationName as a JVM argument with actual file name,

-DApplicationName=Myapp1

Same log4j.properties file can be shared by both applications and you can pass the application name in the JVM parameter for each application.

You can configure the log files for individual class like this -

log4j.logger.com.logger.test.logger_test.MyApp1=DEBUG, appender1
log4j.additivity.com.logger.test.logger_test.MyApp1=false
log4j.appender.appender1=org.apache.log4j.DailyRollingFileAppender
log4j.appender.appender1.File=logs/MyApp1.log
log4j.appender.appender1.layout=org.apache.log4j.PatternLayout

log4j.logger.com.logger.test.logger_test.MyApp2=DEBUG, appender2
log4j.additivity.com.logger.test.logger_test.MyApp2=false
log4j.appender.appender2=org.apache.log4j.DailyRollingFileAppender
log4j.appender.appender2.File=logs/MyApp2.log
log4j.appender.appender2.layout=org.apache.log4j.PatternLayout

Example :

public class Myapp1 {
        
	Logger logger = Logger.getLogger(Myapp1.class);
        
    public Myapp1() {
       	logger.debug("In Myapp1");
    }
}
        
public class Myapp2 {
    Logger logger = Logger.getLogger(Myapp2.class);
        
    public Myapp2() {
    	logger.debug("In Myapp2");
    }
}
        
public class App {
    public static void main( String[] args ){
        Myapp1 myapp1 = new Myapp1();
        Myapp2 myapp2 = new Myapp2();
    }
}
