It's not JBoss which sets the default logging level to DEBUG. Log4j does it. So, in your case the log4j.properties is not being picked up (you can verify this by setting the threshold to INFO in the log4j.properties and still log debug messages. I believe, you will see the debug log even when this threshold is set). For the sake of testing, i would suggest, you move the log4j.properties to the root of the ear file (or some other place which in the ear which is available in the classpath) and try out the trace level logs.
