    JBoss 7.2 per-deployment logging does not work with slf4j and log4j

    Przemyslaw Bielicki Newbie

      According to JBoss documentation when you provide log4j.properties JBoss should respect such settings - https://docs.jboss.org/author/display/AS72/Logging+Configuration#LoggingConfiguration-PerdeploymentLogging

       

      I created a simple application to reproduce the issue. Settings from log4.properties (located in WEB-INF/classes) are ignored. Basically, nothing is logged from the context listener shown below (not even System.err). When I remove log4j.properties I see the logs but settings are taken from standalone.xml - definitely not what I was expecting.

       

      Does anyone know why it does not work? Am I missing something?

       

      Simple app in question:

       

      @WebListener

      public class LoggingContextListener implements ServletContextListener {

        @Override

        public void contextInitialized(ServletContextEvent sce) {

          System.err.println("Trying to log something using SLF4J-Log4J");

          org.slf4j.Logger logger = org.slf4j.LoggerFactory.getLogger(getClass());

          logger.error("Hello");

          logger.warn("anybody home?");

          logger.info("can you hear me?");

          logger.debug("WTF?");

          System.err.println("Did you notice any logs?");

        }

       

        @Override

        public void contextDestroyed(ServletContextEvent sce) {

        }

      }

       

      with the following log4j.properties:

       

      log4j.rootLogger=WARN, stdout

      log4j.appender.stdout=org.apache.log4j.ConsoleAppender

      log4j.appender.stdout.Target=System.out

      log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

      log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

       

      and pom.xml:

      BTW. Logs after removing log4j.properties:
