Thanks both, I'm in the process of checking out XLogger, slf4j-ext and LoggerWrapper. While doing this, some more (maybe stupid) questions, just to clarify: - Given what you said, I think I can't even create my own LoggerFactory and tell logback to use it (from logback.xml). Is this scenario possible? Because that would fix my issue. In short, I'd need to tell logback, through logback.xml to use my implementation of Logger. - Is there a way (I guess no, considering what Ceki said), to set Logger paramemters from inside <logger>, like I did in the log4j days using <param name="foo" value="1"> ? The answer is probably obvious, but better safe than sorry ;-). - Given the absence of a .dtd, is there a way to figure out all the supported parameters of logback.xml ? Thanks a lot -- Fabio Erculiani
