The STATUS_BAR_SERVICE
permission is used for apps that what to be the actual status bar. This is a protected permission so unless you're building your own ROM that includes replacing the status bar then I don't think this is the permission you want.
By the sound of it all you want to do is put notifications in the notification bar. So just using the functionality here should be all your interested in. You shouldn't need to mess with any special status bar related permissions.
