Librerie HttpComponent

[stromgald]

Qualcuno è pratico di queste librerie java? Le ho appena scaricate ma ho un problema.
Non riesco a eseguire il login visto che non mi restituisce nessun cookie.
Ad esempio volevo eseguire il login su megalive. Ho utilizzato Il form che è in esempio nelle librerie. Ma i cookie sono sempre vuoti quindi significa che non fa il login.
Ho utilizzato anche Live HTTP Header di firefox per vedere se il link del metodo Post e va bene credo

http://www.megalive.com/?c=login

POST /?c=login HTTP/1.1
Host: www.megalive.com
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:6.0.1) Gecko/20100101 Firefox/6.0.1
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: it-it,it;q=0.8,en-us;q=0.5,en;q=0.3
Accept-Encoding: gzip, deflate
Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7
Connection: keep-alive
Referer: http://www.megalive.com/?c=login

E' la prima volta che le vedo queste librerie ^_^ Se cè qualcuno che le ha gia usate e mi saprebbe dare una diritta su come utilizzarle in questo esempio mi farebbe un piacere

Questo è il codice java invece della classe

        } finally {
            // When HttpClient instance is no longer needed,
            // shut down the connection manager to ensure
            // immediate deallocation of all system resources
            httpclient.getConnectionManager().shutdown();
        }
    }
}

Il risultato che mi dà come gia detto prima è
Login form get: HTTP/1.1 200 OK
Initial set of cookies:
None
Login form get: HTTP/1.1 200 OK
Post logon cookies:
None
