i use jboss 4.2.2 and seam 2.1 and i'm unable to see any Hibernate log on the console.

That's my log4j config :

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

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

<!-- The default pattern: Date Priority [Category] Message\n -->
<param name="ConversionPattern" value="(%thread) %d{ABSOLUTE} %-5p [%c{1}] %m%n"/>
</layout>
</appender>
