log4j configuratiions in JBOSS 4.0.4

[Amir Iqbal]

hello to everyone.
i am working upon the JBoss server and log4j. can anyone please tell me that
1) how can i force jboss to log at specific directory eg. C:/log
2) what will be given prefrence log4j.xml or log4j.properties.
3) i used both but the problem is log4j.properties creates an empty file at my specific
location. and it is unaccessible (meanz donot created) untill i shutdown the JBoss.
4) how can i get diffrent log for diffrent user in diffrent .log files? some one told me
NDC (Nested Diagnostics Context) but i am unable to find even a single complete example
of NDC.

here is my log4j.xml file

 
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

JBoss has its own log4j.xml file under %JBOSS_HOME%/server/< serverName>/conf folder. The log4j config files in the application's package are ignored. Add your configurations to the log4j.xml present in JBoss' conf folder.
