       System.setProperty("java.protocol.handler.pkgs", "com.sun.net.ssl.internal.www.protocol");
       Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider()); 
       System.setProperty("javax.net.ssl.keyStoreType", "PKCS12");
       System.setProperty("javax.net.ssl.keyStore", "Certificado.pfx");
       System.setProperty("javax.net.ssl.keyStorePassword", "***");
       System.setProperty("javax.net.ssl.trustStoreType", "JKS");
       System.setProperty("javax.net.ssl.trustStore", "nfe.keystore");

	    System.out.println(soap);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.addRequestProperty("Request-Method", "POST");

            OutputStream out = connection.getOutputStream();
            out.write(soap.getBytes());
            out.flush();
            connection.connect();
            if (connection.getResponseCode() == HttpURLConnection.HTTP_OK || connection.getResponseCode() == HttpURLConnection.HTTP_ACCEPTED) {
                BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream()));
                StringBuffer newData = new StringBuffer();
                String s = "";

            }
            connection.disconnect();
