No more JMSAppender documentation

Hi, The JMSAppender and its subclasses are still provided with Logback, but the documentation for those classes has been removed from the site. It seems it has happened between 24 october 2010 and 19 november 2010 (between 0.9.24 and 0.9.26 versions). I have found a way to access the old version of the documentation with the Wayback Machine, but it's not really a convenient one. Any idea why it's gone and if it will be restored? Do you plan to remove those classes from Logback? Thanks for your great log library. Stéphane

Question of dropping logs when using SimpleSocketServer and SocketAppender
by Yudong Li 12 Sep '13

12 Sep '13

Hi, I've got some issues while using Socket to send logs to a central repository. When the logs generated from client side is slow, everything works fine. However, if the logs from client side is very fast, it looks like logs entries will be dropped significantly during transmit. I did an experiment to confirm it: int i = 0 ; while (i < 10000) { log.info(i + " : ======="); i ++; } And on the sever side, the received log looks like: 2013-09-12 17:59:09,174 INFO [main] - 0 : ======= 2013-09-12 17:59:09,175 INFO [main] - 5 : ======= 2013-09-12 17:59:09,175 INFO [main] - 10 : ======= 2013-09-12 17:59:09,176 INFO [main] - 13 : ======= 2013-09-12 17:59:09,177 INFO [main] - 17 : ======= 2013-09-12 17:59:09,178 INFO [main] - 21 : ======= Is there any way to avoid this from happening? What I have read from doc is logback is based on TCP so eventual consistency should be able to achieved, or may be my understanding is not correct? Thanks if anyone can give me some hint. Regards, Yudong

Programmatic configuration
by Kristoffer Sjögren 04 Sep '13

Hi I would like to handle logback configuration programmatically - without files (XML, Groovy, etc). My problem is that I cant find an obvious way to override the fallback behavior in ContextInitializer.autoConfig, which ultimately result that a ConsoleAppender is created by BasicConfigurator (since no URL was found for Joran). It would be nice to if BasicConfigurator could be replaced for something else, maybe using http://docs.oracle.com/javase/6/docs/api/java/util/ServiceLoader.html or something similar. Maybe adding an modified copy of BasicConfigurator (but with same fully qualified classname) first on classpath would be possible? But this feels more like a hack. Cheers, -Kristoffer

Object Rendering for Logback as Log4j
by gaston sponer 03 Sep '13

03 Sep '13

Hi, Any answer for this?Hi, I am new to logback, and I was asked to migrate our project from log4j to logback. I was wondering if there's any kind of support for object rendering such as in log4j. This is what we're now doing with log4j. public static LoggerRepository getLoggerRepository() { if (loggerRepository == null) { loggerRepository = org.apache.log4j.LogManager.getLoggerRepository(); } return loggerRepository; } public static RendererSupport getRendererSupport() { LoggerRepository lr = getLoggerRepository(); if ((lr != null) && (lr instanceof RendererSupport)) rendererSupport = (RendererSupport) lr; return rendererSupport; } public static ObjectRender getRendererObject(Class<?> clazz) { ObjectRender renderer = getRendererSupport().getRendererMap().get(clazz); return renderer; }
