Configure log4j in weblogic server
I have recently configured log4j for our web applications deployed in weblogic 10.3 domain. The steps are given below:

1. Copy log4j-1.2.9.jar & wllog4j.jar under domain_root/lib folder.
2. Create log4j.xml and drop it under domain_root folder. If you have log4j.xml inside the application(EAR/WAR), I would recommend to move outside EAR/WAR
   as changing severity (log level) would require re-deployment.
   To avoid this, we can move log4j.xml into domain root folder but again the server needs to be bounced. But there is a fix. Click here for more info.
3. Login to weblogic server console. Go to Servers -> Admin Server-> Logging.
   Click on advanced mode. Change the logging implementation from JDK to Log4J. Click save.
4. Activate changes. Re-start the admin server.

This should enable log4j and should write logging into log file mentioned in log4j.xml or properties file.

if you want an example i recommend this log4j – Quick Guide

advice you should be patience to read and apply
