Fazer Request à url https

#1

Olá, estou precisando fazer uma requisição https que requer autenticação via certificado digital, depois de várias tentativas estou utilizando o commons-httpclient. Antes eu gerei meu keystore e importei meu certificado digital para este. Utilizando o exemplo que consta na documentação do commons implementei a classe abaixo:

[code]DefaultHttpClient httpclient = new DefaultHttpClient();

    KeyStore trustStore  = KeyStore.getInstance(KeyStore.getDefaultType());        
    FileInputStream instream = new FileInputStream(new File("c:/workspace/certificados/certificado.keystore")); 
    try {
        trustStore.load(instream, "123456".toCharArray());
    } finally {
        instream.close();
    }
    
    SSLSocketFactory socketFactory = new SSLSocketFactory(trustStore);
    Scheme sch = new Scheme("https", socketFactory, 443);
    httpclient.getConnectionManager().getSchemeRegistry().register(sch);

    HttpGet httpget = new HttpGet("https://cav.receita.fazenda.gov.br/scripts/CAV/login/login.asp");

    System.out.println("executing request" + httpget.getRequestLine());
    
    HttpResponse response = httpclient.execute(httpget);
    HttpEntity entity = response.getEntity();

    System.out.println("----------------------------------------");
    System.out.println(response.getStatusLine());
    if (entity != null) {
        System.out.println("Response content length: " + entity.getContentLength());
    }
    if (entity != null) {
        entity.consumeContent();
    }

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

Porém ao executar a exceção é lançada:

Exception in thread “main” javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated

Alguém tem alguma idéia?
