Hi, I've created a Web Service application inside Jboss 4.2.2-GA and I want to set up the jboss log4j configuration so that my Web Service logs inside a custom log file (not inside the server.xml).
 
 To do this I've altered the jboss-log4j.xml file to create another appender. This file is below:
 
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE log4j:configuration SYSTEM "log4j.dtd"><!-- ===================================================================== --><!--

 After that I created a logger inside my Web Service with the same name as the category tag and logged the message received by the service:
 
logger = Logger.getLogger("AfisLogger");
logger.debug(message);
 
However I noticed that even though the log file afis_interfaces.log is indeed created, it remains empty as if I wasn't writing anything to it.
 
 Please help me.
 
 Thanks,
 Komyg
