Exception working with TWILIO Send SMS API in GAE

Question

I am trying to send sms to a number and it works perfectly fine. This is my code.

public class SendSMSExample {

public  void sendSMS(String data) throws Exception {

String url = "https://api.twilio.com/2010-04-01/Accounts/XXXXXXXXXXXXXXX/Messages";
    URL url1 = new URL(url);
    URLConnection conn = url1.openConnection();
    conn.setDoOutput(true);

    OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream(), "UTF-8");

        wr.write("data");

     TwilioRestClient client = new TwilioRestClient(ACCOUNT_SID, AUTH_TOKEN);
        Account account = client.getAccount();

        //Use the API to send a text message
        SmsFactory smsFactory = account.getSmsFactory();
        Map<String, String> smsParams = new HashMap<String, String>();
        smsParams.put("To", "+1408XXXXXXX"); 
        smsParams.put("From", "(508)XXX-XXXX"); // Replace with a Twilio phone number in your account
        smsParams.put("Body", "Hello");
        try
        {
            Sms sms = smsFactory.create(smsParams);
        }
        catch (TwilioRestException e)
        {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    // Create an instance of the SmsFactory class.

        wr.flush();


     // Get the response
        BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
        String output = "";
        String inputLine;
        while ((inputLine = reader.readLine()) != null)
        {
            output += inputLine;
        }

        wr.close();
        reader.close();


}

}

But when I put the same code in my project on which I usually work on, I get exceptions. Following is code with exceptions

public class SendMessage extends TaskAdapter {

public static final String ACCOUNT_SID = "XXXXXXXXXXXXXXX";
public static final String AUTH_TOKEN = "XXXXXXXXXXXXXXX";

public static String PHONE_NUMBER = "from";
public static String MESSAGE = "message";

public void run(JSONObject x, JSONObject xx,
        JSONObject xxx, JSONObject xxxx) throws Exception {

    String from_phone_number = getStringValue(x, xx,
            xxx, xxxx);

    String message = getStringValue(x, xx,
            xxx, xxxx));

    String url = "https://api.twilio.com/2010-04-01/Accounts/XXXXXXXXXXXXXXX/Messages";
    URL url1 = new URL(url);
    URLConnection conn = url1.openConnection();
    conn.setDoOutput(true);

    OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream(),
            "UTF-8");

    wr.write("data");
    TwilioRestClient client = null;
    try {
        ***client = new TwilioRestClient(ACCOUNT_SID, AUTH_TOKEN);***
    } catch (Exception e) {
        System.out.println(e);
        e.getStackTrace();
    }
    Account account = client.getAccount();

    // Use the API to send a text message
    SmsFactory smsFactory = account.getSmsFactory();
    Map<String, String> smsParams = new HashMap<String, String>();
    smsParams.put("To", XXXX);
    smsParams.put("From", XXXX); // Replace with a Twilio phone
                                                // number in your account
    smsParams.put("Body", "Hello 123");
    try {
        Sms sms = smsFactory.create(smsParams);
    } catch (TwilioRestException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    // Create an instance of the SmsFactory class.

    wr.flush();

    // Get the response
    BufferedReader reader = new BufferedReader(new InputStreamReader(
            conn.getInputStream()));
    String output = "";
    String inputLine;
    while ((inputLine = reader.readLine()) != null) {
        output += inputLine;
    }

    wr.close();
    reader.close();

}

}

I am getting exception at this line client = new TwilioRestClient(ACCOUNT_SID, AUTH_TOKEN); I am using this jar version twilio-java-sdk-3.4.6-jar-with-dependencies And the exception is:

Thanks in advance :)

You should XXX out the ACCOUNT_SID and AUTH_TOKEN and any other unique keys. Did you include all the proper libs? This might be of use: stackoverflow.com/questions/17564775/… — Ryan
I did XX them out and used proper libraries. Not yet resolved. — kona B

This is my code for sending an SMS message. I don't understand why you need a URLConnection, OutputStreamWriter, etc. in your code.

public static void sendSms(String phoneNumber, String message) throws TwilioRestException {

    SmsFactory smsFactory = account.getSmsFactory();
    HashMap<String, String> smsParams = new HashMap<String, String>();
    smsParams.put("To", myPhoneNumber); 
    smsParams.put("From", phoneNumber);
    smsParams.put("Body", message);
    smsFactory.create(smsParams);
}
