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.

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 .

Thanks David

Ok ...

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

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

thanks David,

Can you give me a sample code you use, or more details ?

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
