How to disable classloading delegating to the server's loade

[denisius]

I have an apllication (.ear) that uses log4j.jar for logging (it places in this ear). As we know jboss uses its own lo4j.jar from server/lib folder. So when by application starts up it inits log4j with app specific log4j.xml conf file - as a result i see that instead of loading new Logger (from jar in ear) it usses already loadded one - loadded by jboss on start up.
So how to separate loading scopes?

:) all not so easy
i have ear which includes ejb module, several war modeles - modules described in application.xml
also ear has utils.jar - this module doesn't described in app...xml
and at last - folder 'vendor' with different jar's (log4j.jar placed here)
utils.jar used by ejb project
utils.jar uses log4j.jar (from 'vendor' - it has reference to it from manifest file)
i tried to add jboss-app.xml with <loader-repository> tag but it doesn't work. in long debug session :) i found that utils.jar should be added as java module to application.xml - in this case i have some progress
all work while jboss begins to start WAR apps
