Hello,

I am using slf4j and log4j for logging, and I deploy on a Wildfly 10 server.

I wanted to change the logging pattern project wide, not via the standalone.xml, but the log4j2.xml, as explained the log4j configuration documentation[1], was not taken into account.

Now I am using the following jboss-log4j.xml which works:

<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">


<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/" debug="true">


  <appender name="CONSOLE" class="org.apache.log4j.ConsoleAppender">
    <errorHandler class="org.jboss.logging.util.OnlyOnceErrorHandler"/>
    <param name="Target" value="System.out"/>
    <param name="Threshold" value="ALL"/>


    <layout class="org.apache.log4j.PatternLayout">
      <param name="ConversionPattern" value="MYLOG -------- %d{ABSOLUTE} %-5p [%c{1}] %m%n"/>
    </layout>
  </appender>


  <root>
    <appender-ref ref="CONSOLE"/>
  </root>


</log4j:configuration>

My guess is, that Wildfly simply ignores the log4j specific files, is that correct? So I probably have to use the jboss/wildfly specific ones, right?

Thanks in advance!
