public class PdtServlet extends AbstractTeleTrakController {
protected void processRequest(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException,
TeleTrakDatabaseException, TeleTrakGeneralException {
DirectCallDeligate directCallDeligate = new DirectCallDeligate(request);
String action = request.getParameter("userAction");
String page="";
String paypalTransactionId=null;
Map paramterMap=request.getParameterMap();
int noOfParameters=paramterMap.size();
System.out.println("noOfParameters==>"+noOfParameters);
//Returned From paypal
String firstName=null;
String lastName=null;
String paymentStatusFromPaypal=null;
String paymentAmount=null;
String currency=null;
String customValueWeHaveSend=null;
int dealerId=0;
int noOfTollFreeNos;
int totalCharges;
String paymentMethod="";
if(noOfParameters==1){
//Paypal is pinging our servlet with tx code
paypalTransactionId=request.getParameter("tx");
PayPalHelper payPalHelper = new PayPalHelper();
String identityToken= payPalHelper.getPdTIdentity();
OutputStreamWriter streamWriter=null;
HttpURLConnection urlConnection=null;

String urlToBePosted =payPalHelper.getPayPalSiteURL();
StringBuffer dataToPostBuffer = new StringBuffer();
try{
dataToPostBuffer.append("cmd=");
dataToPostBuffer.append("_notify-synch");
dataToPostBuffer.append("&tx=");
dataToPostBuffer.append(paypalTransactionId);
dataToPostBuffer.append("at=");
dataToPostBuffer.append(identityToken);

urlConnection = (HttpURLConnection)url.openConnection();
urlConnection.setDoOutput(true);
urlConnection.setDoInput(true);
urlConnection.setUseCaches(false);
urlConnection.setRequestMethod("POST");
streamWriter = new OutputStreamWriter(urlConnection.getOutputStream());
streamWriter.write(dataToPostBuffer.toString());
streamWriter.flush();
Properties paypalProperties = new Properties();
paypalProperties.load(urlConnection.getInputStream());
reader = new BufferedReader(new InputStreamReader(urlConnection.getInputStream()));
StringBuffer returnBuffer = new StringBuffer();
String lineToRead;
while((lineToRead=reader.readLine())!=null){
returnBuffer.append(lineToRead);
}//end of while

//if("SUCCESS".equalsIgnoreCase(returnBuffer.toString().substring(0,7))==true){
paymentStatusFromPaypal= paypalProperties.getProperty(payPalHelper.getPayPalPdtPaymentStatusField());
if(paymentStatusFromPaypal.equalsIgnoreCase("Completed")){
//Payment is sucess
