I am trying to create a REST API call to import a template into my NiFi UI post which Instantiate the same.
Below is the code which I tried, String pathname = "D:\\Users\\bramasam\\Downloads\\BalaBackUp.xml";
String restString = "http://localhost:8080/nifi-api/process-groups/f80896d4-c71f-3395-d527-8c6bd69f44d0/templates/upload";
HttpPost httpPost = new HttpPost(restString);
File fileObj = new File(pathname);
httpPost.addHeader("Content-type", "multipart/form-data");
FileEntity fileEntity = new FileEntity(fileObj, ContentType.MULTIPART_FORM_DATA);
httpPost.setEntity(fileEntity);
HttpClient httpClient = HttpClientBuilder.create().build();
HttpResponse response = httpClient.execute(httpPost);
StatusLine status = response.getStatusLine();
System.out.println(status.getStatusCode()); I am getting a response code of 500 and with the below response HttpResponseProxy{HTTP/1.1 500 Internal Server Error [Date: Thu, 28 Sep 2017 09:43:28 GMT, X-Frame-Options: SAMEORIGIN, Content-Type: text/plain, Transfer-Encoding: chunked, Server: Jetty(9.4.3.v20170317)] ResponseEntityProxy{[Content-Type: text/plain,Chunked: true]}} Below is the {id} from the BalaBackUp.xml file which I am trying to import from <?xml version="1.0" ?>
