Hi - noobie here - I'm doing a simple L4J Logging with WebLogic 10.3.

I have setup a simple WebLogic project - with the following in my WEB-INF/classes: commons-logging.properties and log4j.properties.

I have Servers ->  Admin Server-> Logging set to L4J.

I have downloaded the log4j-1.2.16.jar and placed it in the WEB-INF/lib folder of the project. I also put wllog4j.jar in the WEB-INF/lib folder. I put the log4j-1.2.16.jar and wllog4j.jar in the build-path of the project as well.

I do a build all - and publish the corresponding EAR to my WebLogic Server and keep on getting the following error in the console:

java.lang.ClassNotFoundException: weblogic.logging.log4j.JDKLog4jAdapterFactory

I have all my files positioned in the right folders correct for deployment? So why am I getting this error?

Please try this

You need to source the wllog4j.jar  to your domain library folder
