Are log4j and log4cxx configuration files identical?

["Zmuda, Matthew" <Ma...@tvworks.com>]

I am coding a JNI project and planning to use log4j in java portion and log4cxx in c++. Can the same configurations files be used for both?

If I change logging level at runtime in Java will the changes also be made in c++ logger?

Finally can both Java and C++ loggers log to the same file?

Thanks,

The same configuration file format is used for both but probably you will have 
different class names for C++ and Java. So you will need to define loggers depending
on the class, package etc. Probably you can define a naming scheme for classes so 
the loggers apply to both parts.

See above

Yes I thinks so, by defining appenders that log to the same file. 

Scroll down for appenders
http://logging.apache.org/log4cxx/index.html
http://logging.apache.org/log4j/1.2/manual.html

Attached is a file I'm using for logging, I think it's self explanatory.
