HttpClient's HttpResponse returns non formatted String

I have created a post request which is executed using the HttpClient. This returns me a response, and from that I retrieve the entity, and convert it to a string to read the response value. The response contains the correct data, but it loses all relevant XML tags, and contains only the data. However, when I make this exact post request through CURL or Postman, the response contains the XML tag. I am unable to figure out what I am doing wrong. This is what I have tried:

// Create HTTP Post Request
HttpPost requestPost = new HttpPost(url);
// Create Auth
String auth = username + ":" + password;
byte[] encodedAuth = Base64.encodeBase64(auth.getBytes());
String authHeader = "Basic " + new String(encodedAuth);
requestPost.setHeader(HttpHeaders.AUTHORIZATION, authHeader);
requestPost.setHeader("Content-Type", "application/x-www-form-urlencoded");
// Create the request parameter body
List<BasicNameValuePair> urlParameters = new ArrayList<>();
urlParameters.add(new BasicNameValuePair("functionName", functionName));
urlParameters.add(new BasicNameValuePair("objectType", objectType));
urlParameters.add(new BasicNameValuePair("inputParameter", inputParameter));
urlParameters.add(new BasicNameValuePair("inputTableParameter", inputTableParameter));
// Execute request
UrlEncodedFormEntity entity = new UrlEncodedFormEntity(urlParameters);
requestPost.setEntity(entity);
// bypass SSL security
SSLContext context = SSLContext.getInstance("TLSv1.2");
TrustManager[] trustManager = new TrustManager[] {
new X509TrustManager() {
@Override
public X509Certificate[] getAcceptedIssuers() {
return new X509Certificate[0];
}
@Override
public void checkClientTrusted(X509Certificate[] certificate, String str) {}
@Override
public void checkServerTrusted(X509Certificate[] certificate, String str) {}
}
};
context.init(null, trustManager, new SecureRandom());
SSLConnectionSocketFactory socketFactory = new SSLConnectionSocketFactory(context,
SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
HttpClient client = HttpClientBuilder.create().setSSLSocketFactory(socketFactory).build();
HttpResponse response = client.execute(requestPost);
//Get response
String result = EntityUtils.toString(response.getEntity(), "UTF-8");
return result;

Without posting all the results, my final result looks something like this:
Results 002020-07-31100In Process2020-07-312020-07-312020-07-3100002210000825255003Calculated00002210000825255EUREuro0012020-07-3100:00:00
... etc

But from postman or CURL it is nicely formatted with the XML tags:

<OUTPUT>
<EN_ERROR_CD>00</EN_ERROR_CD>

...etc

For reference this is how my CURL request looks like:

curl -u username:password -d "functionName=/RETRIEVE&objectType=obj&inputParameter=<INPUT><IV_APPLNR_CD>10000000002553402</IV_APPLNR_CD><IS_REQUESTED_ELEMENTS></IS_REQUESTED_ELEMENTS><IF_READ_JOURNAL></IF_READ_JOURNAL><IF_READ_CBC>X</IF_READ_CBC></INPUT>&inputTableParameter=" -H "Content-Type: application/x-www-form-urlencoded" -X POST https://hostname:port/test/service/service.do

I hope this information is helpful in illustrating the problem. Thank you very much for your help!

Was able to fix the problem by adding this line when creating the post request:

requestPost.setHeader(HttpHeaders.ACCEPT_CHARSET, "true");
