Hi Ceki, I (again) have some questions about log4j. (I guess Logback works the same way....) I was wondering if there's a way to save a "logger object" to a data structure like a queue or something before sending it to some appender. For example: The socket appender will cause the log4j client to lock/freeze if there's no link to the server. I verified it and it does lock the client. I need to deal with this issue so I'd like to store "logger objects" (or something) before they go to the socket or some other appender first. At the moment I have a wrapper around the log4j that when the debug method is called I'm just calling the log4j debug method passing some args etc. so I have: logger.debug("some stuff"); The configuration file does the trick and outputs to the console (at the moment) all the info: the class name, the method name, the line number etc. I'd like to save this info somehow to some object that I can store in a queue or something. How do I retrieve this information programmatically? Is there a way? I know about LoggingEvent object, could I use it and pass the above stated information to its constructor then store it in a queue? Logger gets me for free (like method name etc.) Any suggestion? Thanks a lot. Greg.
