I am writing a servlet using eclipse that receives POST request from a client that should do some splitting on the received text, access google geolocation api to get some data and display to the user.
On a localhost, this works perfectly fine. On an actual server (tried with Openshift and CloudBees), this doesn't work. I can see the splitting reply but not the reply from google geolocation service. There is always an error logged into the console from google service. However, the same code works perfectly fine on localhost.
After I receive the POST request in the doPost method of the servlet, I am doing the following to access the Google GeoLocation service:
//Attempting to send data to Google Geolocation Service
URL url;
HttpURLConnection connection = null;
try {
//Create connection
url = new URL("https://www.googleapis.com/geolocation/v1/geolocate?key=MyAPI");
connection = (HttpURLConnection)url.openConnection();
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-Type", "application/json");
connection.setUseCaches (false);
connection.setDoInput(true);
connection.setDoOutput(true);
//Send request with data (output variable has the JSON data)
DataOutputStream wr = new DataOutputStream (
connection.getOutputStream ());
wr.writeBytes (output);
wr.flush ();
wr.close ();
//Get Response
InputStream is = connection.getInputStream();
BufferedReader rd = new BufferedReader(new InputStreamReader(is));
String line;
StringBuffer response2 = new StringBuffer();
while((line = rd.readLine()) != null) {
response2.append(line);
response2.append('');
}
rd.close();
//Write to Screen using out=response.getWriter();
out.println("Access Point's Location = " + response2.toString());
} catch (Exception e) {
e.printStackTrace();
} finally {
if(connection != null) {
connection.disconnect();
}
Could you tell me why this is happening and how can I make this work? Should I resort to something like AJAX or is there someother work around? I am relatively new to coding and hence, trying to refrain from learning AJAX at this stage. Please let me if there's any other way of getting this to work
