JAVA - Automatic post on Facebook wall without app

I am trying to simulate a user behavior on Facebook through the org apache HttpClient and currently I am able to login into the user page (obviously having the username and password).

Now I would like to post a simple message on the wall through the common http call that the user makes when he/she clicks on the "submit" button.

I decoded some parts of the ajax call done to the "updatestatus.php" page but I wasn't able to publish into the stream.

My question is: Does anyone already successfully posted on the wall using this kind of开发者_C百科 process?

Just another note: I don't want to register an app for some special reasons.

Thank you C

The correct way to do this is to register an app and use Facebook's APIs. What are the "special reasons" you can't do that?
