Hello logback users, When trying out perf4j's recently added support for logback I followed example from perf4j logback package javadoc which can be found here: http://perf4j.codehaus.org/apidocs/index.html?org/perf4j/logback/package-sum... That example at the moment has a bug, perf4jFileAppender is referenced from a logger, but the appender is listed in configuration file after logger. Logback's AppenderRefAction reports this as an error with following code {code} ... Appender appender = (Appender) appenderBag.get(appenderName); if (appender == null) { String msg = "Could not find an appender named [" + appenderName + "]. Did you define it below in the config file?"; inError = true; addError(msg); addError("See " + CoreConstants.CODES_URL + "#appender_order for more details."); return; } ... {code} Url this produces in logback-classic 0.9.30 is http://logback.qos.ch/codes.html#appender_order When accessed, error codes page opens, but on it there is no explanation for this error and in the page source there is no element with appender_order id. Couldn't find in the history of the codes.html page ( https://github.com/ceki/logback/commits/master/logback-site/src/site/pages/c... ) one revision that ever had this. Am I missing something or is this a bug in logback site? Regards, Stevo.
Hello, I have actually an API which use logback and add some specific functions. this API initialize logback in code : joranConfigurator(myconfig.file) I dont have any logback.xml in my classpath. My question is how can i start this API (and then logback) at application startup before all the other frameworks and APIs (spring, hibernate, axis...) I mean the same way logback init itself with logback.xml at startup Thanks
I assume you're talking about a Web Application. If so, check out javax.servlet.ServletContextListener<http://download.oracle.com/javaee/6/api/javax/servlet/ServletContextListener.html>, it's your best bet. (*Chris*) On Fri, Oct 21, 2011 at 7:47 AM, BAKHTI Mohammed <onlymed@hotmail.com>wrote:

Hello David, sorry about it, My question is in general : as i do a code based configuration using Joran configurator : if i have some frameworks in my applications (a webapp or a jar ....) . those frameworks will init before my api, so they will send some logs to stdout or whatever. My goal : is how can i be sure that my api (which use logback ) is always initialized firt before all the other. is that possible ? If i use a logback.xml i see that logback is always the firt launched. so how can i do the same Thanks CC: logback-user@qos.ch From: nabble@diroussel.xsmail.com Date: Fri, 21 Oct 2011 21:15:45 +0100 To: logback-user@qos.ch Subject: Re: [logback-user] How to start my logback before anything in an application And if it's a command line tool, just initialise log back manually before you create any loggers.

I'm not aware of a single method that will always work regardless of application type. I can't even see how that might work. A web app is very different from a Swing app, which is very different from a command line app, which is light-years from an Android app. The mechanisms are pretty application type specific.

Yes but that will not help me a lot : My original question was about logback how it can always starts first whatever is the context (webapp, command line...) means if i put a logback.xml in my classpath in a webapp i dont need to start a servlet or anything, logback will init alone. So if i can understund how it can starts i can do the same .

Logback will initialise the first time you retrieve a logger from LoggerFactory. If you want it to initialise before anything else you need to take responsibility for retrieving a Logger before anything else runs. How you do this will depend on what kind of application you are creating - it will not, and cannot, be the same between a web app and a cli. If you tell us precisely what kind of application you are trying to write we can give precise advice. Bear in mind that a static call to LoggerFactory.getLogger() will occur the moment a class is loaded. On 24 Oct 2011, at 09:16, BAKHTI Mohammed <onlymed@hotmail.com> wrote:

So if i can understund how it can starts i can do the same .

You have to expose a method from your api and get the application to all it before it does any logging.

And if it's a command line tool, just initialise log back manually before you create any loggers.

Mohammed, It sounds like you want logback to call you own initializer on startup. I don't know if that's supported out of the box. But perhaps you could look into how it could be implemented. Perhaps in logback.xml you could name your own initialiser class, and logback would call it at some point in it's start up sequence.

This was poorly phrased - what I meant was that if a class contains a static field initialised by a call to LoggerFactory.getLogger() then Logback will be initialised the moment that class is loaded (if it wasn't initialised already).
