log4j in EAP 6.4

I am deploying seam 2.2 application in EAP 6.4. In EAP 6, logging dependencies for common third-party frameworks like Apache log4j and SLF4J are added by default. Is it possible to use default log4j library? If yes, how to config log4j properties?

It is described in the document that I need exclude third party logging framework dependencies and then add log4j library into application level for using a log4j.properties or log4j.xml file. Can I just copy log4j jar file from EAP 6 default module? Or I have to download apache log4j library.
