Logging FIX configuration

FEJ uses Log4j 2 as a logging framework. Its configuration is stored in the log4j2.xml file. For more information about configuration, please refer to Log4j 2 official documentation.

A SecurityPatternLayout is recommended to use with FEJ to hide passwords in the application log file:
