To fix this issue 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:
code :
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");
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 think the issue was by ths following , Cloudant Client library available in Java that will store one document at a time, , Here is the code that can enable to upload bulk upload,
code :
CloudantClient client = ClientBuilder.account("accounbt")
                        .username("username").password("password")
                        .disableSSLAuthentication().build();*/

Database db = client.database("databaseName", true);

List<JSONObject> arrayJson = new ArrayList<String>();
arrayJson.add(new JSONObject("{data:hello}"));
arrayJson.add(new JSONObject("{data:hello1}"));
arrayJson.add(new JSONObject("{data:hello2}"));
db.bulk(arrayJson);

like below fixes the issue One way to do this is to use REST services. Your front end code can make a REST call to the back end and let it work its magic. It's a pretty standard approach in industry projects.

this will help Your URL is incorrect, I think.
You are correctly sending your credentials using a Basic Authentication header - they should not be included directly in the URL. Some HTTP libraries / utilities (e.g. cURL) have a feature where they parse the credentials in the URL and convert them into a basic auth header but when using most standard HTTP libraries you will have to do this yourself. The following should work:
