I am reading from Object Storage and making a httpPut call to another target URL, but this call fails with 501 Method Not Implemented. Not sure what I am doing wrong.
import com.oracle.bmc.objectstorage.responses.GetObjectResponse;
...
...
GetObjectResponse getResponse =
client.getObject(
GetObjectRequest.builder()
.namespaceName(namespaceName)
.bucketName(bucketName)
.objectName(objectName)
.build());
try (final InputStream fileStream = getResponse.getInputStream()) {
InputStreamEntity entity = new InputStreamEntity(fileStream, -1);
entity.setContentType("text/html; charset=utf-8");
HttpPut putRequest = new HttpPut("https://MYURL");
putRequest.setEntity(entity);
CloseableHttpClient httpClient = HttpClients.createDefault();
HttpResponse response= httpClient.execute(putRequest);
if (response != null) {
// FOR DEBUGGING System.out.println(response.getStatusLine().getStatusCode());
}
}
catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}}

I am getting the following error message when trying to CALL REST API of Keycloak used HttpClient.The code as following:
ServletRequestAttributes servletRequestAttributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
HttpServletRequest request = servletRequestAttributes.getRequest();
String token = request.getHeader("X-Auth-Token");
String url = authUrl + "/admin/realms/fast/users/"+userId+"/reset-password";
CloseableHttpClient closeableHttpClient = HttpClients.createDefault();
HttpPut httpPut = new HttpPut(url);
httpPut.addHeader("Authorization", token);
httpPut.addHeader("Content-Type ", "application/json");
List<NameValuePair>list = new ArrayList<NameValuePair>();
list.add(new BasicNameValuePair("type", "password"));
list.add(new BasicNameValuePair("value",userPassDO.getNewPassword()));
list.add(new BasicNameValuePair("temporary","true"));
UrlEncodedFormEntity entity;
try {
entity = new UrlEncodedFormEntity(list,"UTF-8");
httpPut.setEntity(entity);
CloseableHttpResponse response = closeableHttpClient.execute(httpPut);
HttpEntity et = response.getEntity();
InputStream in = et.getContent();
int stat= response.getStatusLine().getStatusCode();

e.printStackTrace();
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block

}
The response after execute put request show an error
"HttpResponseProxy{HTTP/1.1 415 Unsupported Media Type [Server: nginx/1.15.3, Date: Tue, 30 Oct 2018 09:13:03 GMT, Content-Length: 0, Connection: keep-alive] [Content-Length: 0,Chunked: false]"
Does anyone have any ideas or encountered this problem?
In my springboot application, I try to return a pdf file with a ResponseEntity-Resource- to mock a service. So I can't change the return type of this method.
My code :
#RequestMapping(
value = "/pdf",
produces = MediaType.APPLICATION_PDF_VALUE,
method = RequestMethod.GET
)
public ResponseEntity<Resource> getpdf() {
try {
ClassPathResource pdfFile = new ClassPathResource("sample.pdf");
HttpHeaders headers = new HttpHeaders();
headers.add(HttpHeaders.ACCESS_CONTROL_ALLOW_ORIGIN, "*");
headers.add(HttpHeaders.ACCESS_CONTROL_ALLOW_METHODS, "GET, POST, PUT");
headers.add(HttpHeaders.ACCESS_CONTROL_ALLOW_HEADERS, "Content-Type");
headers.add(HttpHeaders.CACHE_CONTROL, "no-cache, no-store, must-revalidate");
headers.add(HttpHeaders.PRAGMA, "no-cache");
headers.add(HttpHeaders.EXPIRES, "0");
headers.add(HttpHeaders.CONTENT_DISPOSITION, "attachment;filename=" + pdfFile.getFilename());
headers.add(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_PDF_VALUE);
log.info("pdfFile.contentLength() : " + pdfFile.contentLength());
return ResponseEntity
.ok()
.headers(headers)
//.contentLength(pdfFile.contentLength())
//.contentType(MediaType.APPLICATION_PDF)
.body(new InputStreamResource(pdfFile.getInputStream()));
} catch (IOException e) {
log.error("Couldn't serialize response for content type ", e);
return new ResponseEntity<>(HttpStatus.INTERNAL_SERVER_ERROR);
}
}
When I try to call this get with postman or swagger I have a 406 with response header :
{
"date": "Fri, 02 Nov 2018 14:04:44 GMT",
"content-length": "0",
"content-type": null
}
Does anyone have an idea?
Swagger response
way too complex.. downloading a file is much more easy
#GetMapping(value="printing/",produces= MediaType.APPLICATION_PDF_VALUE)
public #ResponseBody byte[] print(#RequestParam("filterParam") String filterParam) {
try {
FileInputStream fis= new FileInputStream(new File("path to your file"));
byte[] targetArray = new byte[fis.available()];
fis.read(targetArray);
return targetArray;
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
You can remove produces = MediaType.APPLICATION_PDF_VALUE.
There is no need to add produces = MediaType.APPLICATION_PDF_VALUE, in RequestMapping as it seems to try to convert the ResponeBody internally.
Below line of code is enough which you are already using.
headers.add(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_PDF_VALUE);
I am getting data by http get through restful webservice hosted on IIS7 but when i am trying to put data i am having problem
MY code for put is as follows:
public Void put(String url, List<NameValuePair> data)
{
String response="";
HttpPut put = new HttpPut(url);
String dataString=data.toString();
HttpClient httpclient = new DefaultHttpClient();
try {
StringEntity entity = new StringEntity(dataString, "UTF-8");
entity.setContentType("x-www-form-urlencoded; charset=UTF-8");
put.setEntity(entity);
HttpResponse httpResponse1 = httpclient.execute(put);
StatusLine statusLine = httpResponse1.getStatusLine();
}catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
httpclient.getConnectionManager().shutdown();
}
}
The response i am getting is 405 Method not allowed, Can anybody tell me what is the problem?
You just have to uncheck webdave feature from the IIS menu which is in the window's features

What its wrong?
Applet is signed and compiled with java 1.6, httpclient-4.1.3.jar
For those with this problem, the solution was here http://hc.apache.org/httpcomponents-client-ga/tutorial/html/connmgmt.html#d5e571 getting the JRE Proxy.
DefaultHttpClient client = new DefaultHttpClient () ;
ProxySelectorRoutePlanner routePlanner = new ProxySelectorRoutePlanner(
client.getConnectionManager().getSchemeRegistry(),
ProxySelector.getDefault());
client.setRoutePlanner(routePlanner);
HttpResponse response = client.execute(requestBase) ;
Then i signed all libraries httpcore-4.2.3.jar, httpmime-4.2.3.jar and httpclient-4.2.3.jar.
I have tried in many different ways to send my xml document over a socket connection between a server and a client without closing the socket after sending (keep the outputstream open, for sending another document). I have found several sites who claimed that it should work, so I tried it in all the ways they sugested, but I did not found a way which works.
(that describes the same what I would like to do: http://jaxb.java.net/guide/Designing_a_client_server_protocol_in_XML.html)
The follwing code works perfectly if I am closing the socket after sending (#code marsh.marshal(element, xsw);), but it stucks on unmarshaling on the server side, if I try to keep the socket open.
