Exception working with TWILIO Send SMS API in GAE - google-app-engine

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:
java.lang.NoSuchMethodError: org.apache.http.conn.scheme.Scheme.(Ljava/lang/String;ILorg/apache/http/conn/scheme/SchemeSocketFactory;)V

Thanks in advance :)

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);
}
