Hello Mutaz, it looks like the response contains a www-authenticate header that we don't handle at this moment: WWW-Authenticate: OAuth "Facebook Platform" "invalid_token" "Invalid OAuth access token."
The specification of oauth (http://oauth.net/core/1.0/#rfc.section.5.4) indicates that: This section defines an [RFC2617] <http://oauth.net/core/1.0/#RFC2617>extension to support OAuth. It uses the standard HTTP Authorization and WWW-Authenticate headers to pass OAuth Protocol Parameters. According to the RFC 2617, the WWW-authenticate looks like: auth-scheme = token auth-param = token "=" ( token | quoted-string ) challenge = auth-scheme 1*SP 1#auth-param WWW-Authenticate = "WWW-Authenticate" ":" 1#challenge I'm not convinced the header value follows this rule. But, it seems that the interpretation is quite restrictive, we may relax the parsing logic in order to not stop the process. Best regards, Thierry Boileau I have the following code > > > String openGraphUri = "https://graph.facebook.com/";; > String accessToken = "gerkjh43kj5h43kjh34k"; > ClientResource clientResource = new > ClientResource(openGraphUri + "me/feed" + "?access_token=" + accessToken); > Form form = new Form(); > form.add("message", "test message"); > Representation resp = clientResource.post(form); > > When I run it I get the below exception.
