How log4j log file name or path can be changed at runtime? Let's say if log4j has been initialized using: PropertyConfigurator.configure(log4jConfigFile); How later, in the runtime, the supplied filename to specific appender can be changed from the java code inside the application using log4j.

How log4j log file name or path can be changed at runtime?

Let's say if log4j has been initialized using:



PropertyConfigurator.configure(log4jConfigFile);



How later, in the runtime, the supplied filename to specific appender can be changed from the java code inside the application using log4j.

Example:

1) in log4jConfigFile we had:

# file log

log4j.appender.R=org.apache.log4j.RollingFileAppender

log4j.appender.R.File=/home/mylogs/mylogfile.log

log4j.appender.R.MaxFileSize=1000KB



2) log4j was initialized with

PropertyConfigurator.configure(log4jConfigFile);



3) now we want to re-direct the log to file /home/hislogs/mylogfile.log

... talking to me :)



RollingFileAppender appndr=logger.getAppender("R");

appndr.setFile("/path/filename.log");

appndr.activateOptions();
