Question

I’m trying to obtain a result from a web service in a java program. I’ve done xml services before but this one is text based and i can’t figure out how to record the response.

Here is the webService: http://ws.geonames.org/countryCode?lat=47.03&lng=10.2

Thanks!

Answer 1

If it’s only text, and you doesn’t use any standard format (like SOAP), you need to use Sockets:

URL myURL = new URL("http://ws.geonames.org/countryCode?lat=47.03&lng=10.2");
URLConnection serviceConnection = myURL.openConnection();
BufferedReader in = new BufferedReader(new InputStreamReader(
                               serviceConnection.getInputStream()));

List<String> response =new ArrayList<String>();

Use this if you had many lines:

while ((inputLine = in.readLine()) != null) 
   response.add(inputLine);

Or use this if you had ONLY ONE line (like the Web Service in your question):

String countryCode = in.readLine();

And finish with:

serviceConnection.close();

In my case, countryCode it was “AT”
