Issue while configuring Log4j2 in JBoss EAP 6.4 domain mode

I am trying to integrate log4j2, with our web module but unfortunately, I am getting a lot of issues. I am trying to configure this in a domain mode and the log is from one of a host cost controller.

I have tried various ways to fix this issue but nothing works. Looked at the below forum answer, seems it's not working for me. I will appreciate if someone helps me to fix this issue or point out a solution.
