Re: what is the different between "log4j.configuration" and "log4j.properties"

The ".configuration" name is a system property, see the -D JVM option.
It points to a file name. The ".property" name is a file name.

what is the different between "log4j.configuration" and "log4j.properties"

2013-01-04 Thread Shitian Long
Hello 

I am wondering what is the different between "log4j.configuration" and 
"log4j.properties". 
According to the book "Pro Apache Log4j Second Edition"

Quote:

1: The LogManager class looks for the system property log4j.configuration.

2: If the log4j.configuration property is not defined, then it tries to look 
for a resource named log4j.properties/log4j.xml in the application class path.

From my understanding " log4j.configuration" is a properties plain text file, 
only different with log4j.properties is extensions. My question is what is the 
purpose of check log4j.configuration first.

Thanks
