Wiem, że jest wiele różnych pytań i tak wiele odpowiedzi na ten problem ... Ale nie mogę zrozumieć ...

Mam: ubuntu-9.10-desktop-amd64 + NetBeans6.7.1 zainstalowany „tak jak jest” od wyłączenia. rozpustnik. Potrzebuję połączyć się z jakąś witryną przez HTTPS. W tym celu używam Apache's HttpClient.

Z samouczka przeczytałem:

„Po prawidłowym zainstalowaniu JSSE bezpieczna komunikacja HTTP przez SSL powinna być taka sama
prosta jak zwykła komunikacja HTTP. ”I kilka przykładów:

HttpClient httpclient = new HttpClient();
GetMethod httpget = new GetMethod("https://www.verisign.com/"); 
try { 
  httpclient.executeMethod(httpget);
  System.out.println(httpget.getStatusLine());
} finally {
  httpget.releaseConnection();
}

Do tej pory piszę to:

HttpClient client = new HttpClient();

HttpMethod get = new GetMethod("https://mms.nw.ru");
//get.setDoAuthentication(true);

try {
    int status = client.executeMethod(get);
    System.out.println(status);

    BufferedInputStream is = new BufferedInputStream(get.getResponseBodyAsStream());
    int r=0;byte[] buf = new byte[10];
    while((r = is.read(buf)) > 0) {
        System.out.write(buf,0,r);
    }

} catch(Exception ex) {
    ex.printStackTrace();
}

W rezultacie mam zestaw błędów:

Co mam zrobić, aby utworzyć najprostsze połączenie SSL? (Prawdopodobnie bez menedżera KeyManager i Trust itp., Podczas gdy.)
