I have the same problem. I excluded  <module name="org.apache.log4j" /> from deployement in jboss-deployment-structure.xml. If I don't define any class in log4j.xml, then I get NullPointerException, when I write message. If I write class name in log4j, I have "ERROR Attempted to append to closed appender ['any class name']. What's wrong? -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/752156#752156] Start a new discussion in Beginner's Corner at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
