    text
    copied!<p>So, I'm developing a java application that will post using API (multipart/form-data and json) When sending it, I get error 500: POST request for "https://xxx.xxxx.xx.xxx/xx/xxxxx" resulted in 500 (Internal Server Error) The customresponseerror says: Could not extract response: no suitable HttpMessageConverter found for response type [java.lang.String] and content type [text/html;charset=utf-8]</p> <p>Here's my code:</p> <pre><code>@Controller public class ActionController { private String interactions; private HttpHeaders createHeaders( ){ return new HttpHeaders(){ { String auth = "xxxx@xxxxx" + ":" + "xxxxxxxxx"; byte[] encodedAuth = Base64.encode( auth.getBytes(Charset.forName("US-ASCII")) ); String authHeader = "Basic " + new String( encodedAuth ); set( "Authorization", authHeader ); } }; } @RequestMapping(value = "/createcontent", method = RequestMethod.GET) @ResponseBody public ResponseEntity&lt;String&gt; sendCreateContent() throws MalformedURLException, IOException, ParseException { RestTemplate restTemplate = new RestTemplate(); HttpHeaders httpHeaders = createHeaders(); List&lt;MediaType&gt; acceptableMediaTypes = new ArrayList&lt;MediaType&gt;(); acceptableMediaTypes.add(MediaType.APPLICATION_JSON); httpHeaders.setAccept(acceptableMediaTypes); httpHeaders.setContentType(MediaType.MULTIPART_FORM_DATA); MultiValueMap&lt;String, Object&gt; cnt = new LinkedMultiValueMap&lt;String, Object&gt;(); ContentDTO contentDTO = new ContentDTO(); contentDTO.setExternal_id("CNT1"); contentDTO.setTemplate_type_id(103); contentDTO.setChannel_id("CHN1"); contentDTO.setTitle("Conteudo1"); contentDTO.setText("Conteudo teste 1"); RulesDTO rules = new RulesDTO(); SimpleDateFormat publish_date = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss-SSS"); java.util.Date pdate = publish_date.parse("2013-12-28 11:18:00-030"); java.sql.Timestamp pubdate = new java.sql.Timestamp(pdate.getTime()); rules.setPublish_date(pubdate); SimpleDateFormat expiration_date = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss-SSS"); java.util.Date edate = expiration_date.parse("2014-12-28 11:18:00-030"); java.sql.Timestamp expdate = new java.sql.Timestamp(edate.getTime()); rules.setExpiration_date(expdate); rules.setNotify_publish(true); rules.setNotify_expiration(false); rules.setHighlihted(true); contentDTO.setRules(rules); InteractionsDTO interactions = new InteractionsDTO(); interactions.setAllow_comment(true); interactions.setAuto_download(false); contentDTO.setInteractions(interactions); cnt.add("content", "contentDTO"); cnt.add("file", "text.txt"); HttpEntity&lt;MultiValueMap&lt;String, ContentDTO&gt;&gt; request = new HttpEntity&lt;MultiValueMap&lt;String, ContentDTO&gt;&gt;(httpHeaders); List&lt;HttpMessageConverter&lt;?&gt;&gt; messageConverters = new ArrayList&lt;HttpMessageConverter&lt;?&gt;&gt;(); FormHttpMessageConverter converter = new FormHttpMessageConverter(); messageConverters.add(converter); CustomResponseErrorHandler errorHandler = new CustomResponseErrorHandler(); restTemplate.setMessageConverters(messageConverters); restTemplate.setErrorHandler(errorHandler); HttpEntity&lt;String&gt; response2 = restTemplate.exchange("https://xxx.xxxx.xx.xxx/xx/xxxx", HttpMethod.POST, request, String.class); String response3 = null; return null; } } </code></pre> <p>Just in case someone wants to see my ContentDTO, InteractionsDTO and RulesDTO, it follows this structure (above) with "getters and setters" and "constructors of supper class" created.</p> <p>Structure:</p> <pre><code>content={ "external_id": 1000, "template_type_id": 103, "channel_id": 226, "title": "Título do Conteúdo", "text": "Descrição do Conteúdo", "rules": { "publish_date": "2012-07-20T11:18:00-03:00", "expiration_date": "2012-08-25T11:18:00-03:00", "notify_publish": true, "notify_expiration": false, "highlighted": true }, "interactions": { "allow_comment": true, "auto_download": false } } </code></pre> <p>Can someone helps me out? </p> <p>Edit: Stacktrace</p> <pre><code>...resulted in 500 (Internal Server Error); invoking error handler
