I do not know either what the ultimate use case of the OP is.
But I could imagine for example some webapps allowing to upload a file, and this jar 
containing a "saveFile" method which saves the file to a different server directory, 
depending on which webapp called it (but without relying for this on a parameter passed by

the webapp or its configuration, and just relying on the URL having been used to call that

(Of course there are other ways to achieve this, but this is just as a non-AAA example).

Gregory, it may be time to tell us something about what you /really/ want to achieve here.
