Hi James, thanks for looking into this.

I did originally exclude the logging subsystem in jboss-deployment-structure.xml, but then I got logging like this in my console:

{code}

{code}

Every line says the time, level and thread twice.

The {code}10:42:20,436 INFO  [stdout] (EE-ManagedExecutorService-default-Thread-1){code} prefix is from JBoss and shouldn't be there, so it only has the logback pattern {code}2017-06-21 10:42:20,436 [EE-ManagedExecutorService-default-Thread-1] DEBUG  ...{code}

>                 URL: https://issues.jboss.org/browse/WFCORE-2995
>             Project: WildFly Core
>          Issue Type: Feature Request
>          Components: Logging
>            Reporter: Geoffrey De Smet

> Wildfly currently supports the following _Per deployment logging_ configurations [1]:
>     logging.properties
>     jboss-logging.properties
>     log4j.properties
>     log4j.xml
>     jboss-log4j.xml
> All of these are stale because they are based on Log4j 1.x format which died about 8 years ago (along with using properties files for logging configuration).
> Modern popular options include Logback (with SLF4J), JBoss Logging and Log4j 2.x. 
> *I regularly see WildFly users (included RH employees) that struggle to configure the logging configuration of their WildFly apps.* Spring Boot does not have this problem.  _To fix this, WildFly should support logback.xml for Per deployment logging too._
> When I add a logback.xml in my war's WEB-INF/classes directory and explicitly add the logback-classic.jar in WEB-INF/lib directory - which works to configure Logback in any other JVM - then WildFly ignores it (~ it says GFY). My logs doesn't show up and developing on WildfFly is a pain due to blindness.
> Fake solution: Configuring the log files per WildFly installation is not practical for developers (it is for sys admins): the log configuration should be in my war's sources on github, so other developers automatically have it without needing to jump to wildfly installation hoops (which is sometimes not possible, think OpenShift).
> Although it's ok that WildFly favors JBoss Logging, it should not dictate it and support other logging systems such as Logback too for the war files at least (= per deployment).
