Log4j: How to retrieve RollingFileAppender's file name and path?

[Guy Home]

Hi,

Can anyone tell me how I can retrieve the file name and path of my Log4j log file from within my java application code?

i.e how can I get my app to return log4j.appender.R.File below as held in my log4j.properties?


# ***** R is set to be a RollingFileAppender.
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=/blah/xxx.log


I'm sure it ought to be pretty simple so many thinaks if you can offier me the answer.

I did work out my own answer to this one, so for anyone else who might need it:

RollingFileAppender x = (RollingFileAppender) Logger.getRootLogger().getAppender("R");
logger.debug("Logging to: " + x.getFile());

This would output:
"Logging to: \blah\xxx.log"

I've used this successfully in http://gmdx.net/log4j/
