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.

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 .

Ok ...

static void main() {
  readCommandLineArgs();
  initLogging();
  initSpringContext();
}

For a better example of how to call spring from you main method see the spring documentation.

How are they launched?  I use spring and hibernate etc, but my main method is in a class with no imports from spring or logback. I do my own setup, the initialise logback (just by setting system properties in my case) the I call into spring. 

Can you do the same?

That what i have done, but all the framworks like spring, axis2, hibernate are launched before so i lost their logs

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

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

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

I assume you're talking about a Web Application.  If so, check out javax.servlet.ServletContextListener, it's your best bet.

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
