log4j-appender seems not working in jboss-logging (AS6 final)

We are using some custom logger based on log4j appenders. I made a jboss-logging.xml configuration but it seems that my log4j-appender doesn't log anything. I'm working in AS6 final version.

I made an example with a standard log4j appender (neither working). The category "com.sample" should be managed by the log4jappender. Every second the bean should write something, but nothing happens, the log file is not even created. I tried with other log4j loggers/ custom loggers and no success.

When activating CONSOLE handler the logs are correctly written in console, but when only using the log4j-appender nothing happens after server started.

The configuration file seems correct , but can't unfortunately check it against a documentation yet.
