Please I am trying to submit a POST to openshift datagrid thru REST with Spring and I am getting the following :

2018-11-19 08:21:47.607 ERROR 7297 --- [nio-8080-exec-2] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path threw exception [Request processing failed; nested exception is org.springframework.web.client.HttpClientErrorException: 401 Unauthorized] with root cause

org.springframework.web.client.HttpClientErrorException: 401 Unauthorized

my code is the following :

@PostMapping("/cachedatagrid")

    public ResponseEntity<String> postAccount(@RequestBody Sample samplep) {

        RestTemplate restTemplate = new RestTemplate();



        String resourceUrl

                = "http://myapp/rest/default";



        ResponseEntity<Sample> response;

        HttpHeaders httpHeaders = this.createHeaders("user", "pwd");



        Sample sample = new Sample();

        sample.setName("sample");



        HttpHeaders httpHeaders2;

        httpHeaders2 = restTemplate

                .headForHeaders(resourceUrl);



        HttpEntity<Sample> requestUpdate = new HttpEntity<Sample>(sample, httpHeaders);



        response = restTemplate.postForEntity(resourceUrl, requestUpdate , Sample.class);



        return new ResponseEntity<String>("POST Response", HttpStatus.OK);

    }

and header content:

private HttpHeaders createHeaders(String username, String password){

        return new HttpHeaders() {{

            String auth = username + ":" + password;

            byte encodedAuth = Base64.encodeBase64(

                    auth.getBytes(Charset.forName("US-ASCII")) );

            String authHeader = "Basic" + new String(encodedAuth);

            set("Authorization", authHeader);

        }};

    }

I am not being able to find out what is wrong with createHeaders. The authorization should bet set.

I am calling the post using postman:
http://localhost:8080/cachedatagrid

I have compared my code to several ones on the web and not being to make it to work.

Please can you provide some guidance on this? I am a couple of days trying to work it out.
