Spring Social Facebook error - spring

Question

I'm using Spring Social Facebook plugin; I have a very simple scenario: I want to display, on my web page, my user account Feeds; so far I have built a very simple JUnit test in order to list my FB wall posts but I'm facing some issues with Spring Social integration
I'm using spring 4.0.5 and spring social 1.1.0
From what I saw in the documentation, I don't need to use the spring social connect framework (maybe I'll use the ConnectionRepository in future in order to not always do a FB and/or twitter connection on every request, but now I don't need to handle several users)
So, after I created a test APP on FB and obtained the appClientID and appClientSecret, I wrote this simple XML configuration:
<?xml version="1.0" encoding="UTF-8"?>

And I wrote this simple java class (I'm behind a proxy but i can reach FB....my network administrator granted me to reach FB):

Instead if I generate an APP Token on FB and directly use it in FacebookTemplate, all works pretty good.
How can I solve this issue? Am I wrong with anything? Any tip is really really appreciated
Thank you
Angelo

There are a couple of things wrong that I see right away. The primary problem you're having is a network problem--not a code problem or a Spring Social problem. Even if your network admin says you can see Facebook, the exception you show tells me otherwise. That's something you'll need to work out on your end.
Once you get past that, I doubt this will work anyway. You obtain your access token via authenticateClient(), which only grants you a client token. But then you try to use it for user-specific requests, such as obtaining the home feed. You must have a user token to do that operation and you can only get a user token via user authorization, aka the "OAuth Dance". Spring Social's ConnectController can help you with that.
