I just completed a project to make FOray's logging a bit more flexible. It now logs from an interface called org.axsl.common.PseudoLogger. Logging levels are the same as those for java.util.logging.Level (in Java 1.4 and higher), except that integrals are used instead of Level instances.
I also wrote an implementation org.axsl.common.AvalonLogger, which FOray uses (for now) when it needs to *create* a logger. Since all loggers in the font system are supplied to the font system (instead of created within it), FOP should simply pass a different implementation to keep its logging consistent within itself. The AvalonLogger is a thin wrapper around an, er, Avalon ConsoleLogger, and is essentially an Adapter between the Avalon logging system and PseudoLogger. A similar approach can be used with whatever logging system FOP decides it wants to use. Writing the adapter should be fairly trivial, and it should be possible to use any logging system with this approach. I hope this makes the integration work a bit easier and the results more satisfactory to FOP. Please let me know if you have questions. Victor Mote
