Logback

/WEB-INF/config/logback-[mode].xml

All the content generators in Berlioz/Bastille use a logging facade (slf4j ) so that the logging framework can be left at the discretion of the developers.

However, Berlioz automatically loads configuration files for the Logback logging framework using the XML syntax.

See http://logback.qos.ch/manual/configuration.html for details.

Sample config

Here are sample logback configurations.
