Will, we haven't had any chance, yet, to write more than design documentation on 1.0dev. 1.0dev uses Jakarta Commons Logging [1] as logging framework. This means that on a standard JDK 1.4 (or higher) system JCL uses JDK logging as its backend by default. For this case you'd have to look up the documentation for JDK logging [2]. It's pretty easy to supply your own logger of choice. The JCL documentation will tell you how to do that.
In contrast to Avalon loggon JCL logging uses more or less the same approach as Log4J which normally fetches the logger per class into a static variable. That's why you can't set a logger directly on the Driver (or rather Fop now) instance. I believe that until the final 1.0 release it is possible that in the area of logging of few things may still change. Probably not the use of JCL but maybe a specialized facility to observe the formatting process programmatically. There's nothing written in stone about that, yet. And until then, consider 1.0dev a moving target. Suggestions and help are welcome.
