URL url = new URL("https://test.domain:443");   
String  keyStore = "server.p12"
String   keyStorePassword = "changeit";    
String  keyPassword = "changeit";    
String   KeyStoreType= "PKCS12";    
String   KeyManagerAlgorithm = "SunX509";    
String   SSLVersion = "SSLv3";    
public HttpURLConnection getHttpsURLConnection(URL url, String  keystore,
    String   keyStorePass,String  keyPassword, String  KeyStoreType
    ,String KeyManagerAlgorithm, String  SSLVersion)
    throws NoSuchAlgorithmException, KeyStoreException,
        CertificateException, FileNotFoundException, IOException,
        UnrecoverableKeyException, KeyManagementException {
    System.setProperty("javax.net.debug","ssl,handshake,record");

    SSLContext sslcontext = SSLContext.getInstance(SSLVersion);
    KeyManagerFactory kmf =  KeyManagerFactory.getInstance(KeyManagerAlgorithm);
    KeyStore ks = KeyStore.getInstance(KeyStoreType);
    ks.load(new FileInputStream(keystore), keyStorePass.toCharArray());
    kmf.init(ks, keyPassword.toCharArray());

     TrustManagerFactory tmf = TrustManagerFactory
            .getInstance(TrustManagerFactory.getDefaultAlgorithm());
    tmf.init(ks);
    TrustManager[] tm = tmf.getTrustManagers();

    sslcontext.init(kmf.getKeyManagers(), tm, null);
    SSLSocketFactory sslSocketFactory = sslcontext.getSocketFactory();
    HttpsURLConnection.setDefaultSSLSocketFactory(sslSocketFactory);
    HttpsURLConnection httpsURLConnection = ( HttpsURLConnection)uRL.openConnection();

    return httpsURLConnection;
