Solution

you need to add a piece of code in CloudantClient.java file under source directory of your project. Please add these lines in CloudantClient class:

String VCAP_SERVICES = System.getenv("VCAP_SERVICES");
                JSONObject vcap;
                vcap = (JSONObject) JSONObject.parse(VCAP_SERVICES);
                cloudant = (JSONArray) vcap.get("cloudantNoSQULDB");
                cloudantInstance = (JSONObject) cloudant.get(0);
                cloudantCredentials = (JSONObject) cloudantInstance.get("credentials");

you can also put this piece of code in a try catch loop as well.

try {
                String VCAP_SERVICES = System.getenv("VCAP_SERVICES");
                JSONObject vcap;
                vcap = (JSONObject) JSONObject.parse(VCAP_SERVICES);
                cloudant = (JSONArray) vcap.get("cloudantNoSQULDB");
                cloudantInstance = (JSONObject) cloudant.get(0);
                cloudantCredentials = (JSONObject) cloudantInstance.get("credentials");
                } 
            catch (IOException e) {
                e.printStackTrace();
            }

I hope it works!
