How to List all Public_Ids in Cloudinary using Cloudinary API?

I have tried my best to make this code work but, Alas! Something is definitely wrong. I am tried to list all public_ids in Cloudinary. but it always prints, null. Below is the code -
import java.util.HashMap;
import java.util.Map;
import com.cloudinary.Api;
import com.cloudinary.Cloudinary;
import com.cloudinary.utils.ObjectUtils;
public class AllResources {
#SuppressWarnings("unchecked")
public static void main(String[] Args) {
Map<String, String> config = new HashMap<>();
config.put("cloud_name", "*******");
config.put("api_key", "**************");
config.put("api_secret", "***************************");
Cloudinary c = new Cloudinary(config);
Api api = c.api();
try {
Map<String, Object> result = api.resources(ObjectUtils.asMap());
System.out.println(result.get("public_id"));
} catch (Exception e) {
e.printStackTrace();
}
}
}

You can do something like the following:
String nextCursor = null;
do {
result = api.resources(ObjectUtils.asMap("max_results", 500, "next_cursor", nextCursor));
nextCursor = result.get("next_cursor");
for (Map.Entry<String, Object> data : result.entrySet()) {
String key = data.getKey().toString();
Object value = data.getValue();
System.out.println(key + value);
}
} while (nextCursor != null);

Itay's code is pseudo code / won't compile. Here is a working version:
Cloudinary cloudinaryApi = new Cloudinary(
ObjectUtils.asMap(
"cloud_name", "YOUR CLOUD NAME",
"api_key", "YOUR API KEY",
"api_secret", "YOUR SECRET KEY"));
ApiResponse result = null;
String nextCursor = null;
do {
try {
result = cloudinaryApi.api().resources(ObjectUtils.asMap("max_results", 500, "next_cursor", nextCursor));
nextCursor = result.containsKey("next_cursor") ? result.get("next_cursor").toString() : null;
if(result.containsKey("resources")) {
List<Map<String,Object>> resources = (ArrayList<Map<String,Object>>) result.get("resources");
for (Map<String,Object> resource : resources) {
if(resource.containsKey("public_id")) {
String publicId = resource.get("public_id").toString();
System.out.println(publicId);
}
}
}
}
catch (Exception e) {
nextCursor = null;
LOG.error(e.getMessage());
}
} while (nextCursor != null);

How to check if byte array is empty or not?

I am using following code to get uploaded file.
#POST
#Path("update")
#Consumes(MediaType.WILDCARD)
public boolean updateWorkBookMaster(MultipartFormDataInput input) {
try {
//get form data
Map<String, List<InputPart>> uploadForm = input.getFormDataMap();
//get uploaded file
List<InputPart> inputParts = uploadForm.get("workBookFile");
MultivaluedMap<String, String> header = inputParts.get(0).getHeaders();
InputStream inputStream = inputParts.get(0).getBody(InputStream.class, null);
byte[] bytes = IOUtils.toByteArray(inputStream);
now i want to check whether this byte[] is empty or not,
while debugging when i have not uploaded any file it shows its length as 9, why its 9 not 0.

You can implement null check for files this way:
import org.glassfish.jersey.media.multipart.ContentDisposition;
import org.glassfish.jersey.media.multipart.FormDataBodyPart;
import org.glassfish.jersey.media.multipart.FormDataMultiPart;
#POST
#Path("update")
#Consumes(MediaType.WILDCARD)
public boolean updateWorkBookMaster(FormDataMultiPart multiPartData) {
try {
final FormDataBodyPart workBookFilePart = multiPartData.getField("workBookFile");
final ContentDisposition workBookFileDetails = workBookFilePart.getContentDisposition();
final InputStream workBookFileDocument = workBookFilePart.getValueAs(InputStream.class);
if (workBookFileDetails.getFileName() != null ||
workBookFileDetails.getFileName().trim().length() > 0 ) {
// file is present
} else {
// file is not uploadded
}
} ... // other code
}

Java JSON recovers only one item

In a desktop software, the user is available to presh a button and refresh the "database".
All the info is provided by an online service which returns JSON responses, those responses are saved into DAT files and then parsed with http://www.json.org/java/index.html in order to be saved into in-memory variables as String. The DAT files are only for break-exception-support.
Ok, so I'd created a SwingWorker class which should:
parse the content from the in-memory variable
iterate through elements
recover items
update a progress bar
This is an example of the JSON code:
{
"key":"value",
"data":{
"Name1":{...},
"Name2":{...},
[...]
}
}
The full iteration of the "data" element will create a List, which I must use to create a JTable and populate the main frame of the GUI. But when executing the SwingWorker, it only returns a List which all elements are the last item of the JSON.
Here's the code the SwingWorker:
package com.wolfchamane.lolapi;
import com.wolfchamane.logging.LoCLogger;
import java.io.File;
import java.io.FileOutputStream;
import java.io.InputStream;

UPDATE
This is the complete JSON I want to parse:
https://global.api.pvp.net/api/lol/static-data/euw/v1.2/champion?champData=tags&api_key=d34be821-7f22-4d55-85da-7409413e6379

I dont think your JSON example is well formed. JSON consists of name value pairs. There should be a ":" in between the name and a value.
Something like this:
{
"glossary": {
"title": "example glossary",
"GlossDiv": {
"title": "S",
"GlossList": {
"GlossEntry": {
"ID": "SGML",
"SortAs": "SGML",
"GlossTerm": "Standard Generalized Markup Language",
"Acronym": "SGML",
"Abbrev": "ISO 8879:1986",
"GlossDef": {
"para": "A meta-markup language, used to create markup languages such as DocBook.",
"GlossSeeAlso": ["GML", "XML"]
},
"GlossSee": "markup"
}
}
}
}
}
The JSON example you have provided looks malformed. Refer to json.org for more details

HtmlViewService in OBIEE Web Service API is not rendering report (it's only showing spinning loader)

I have a Java application that leverages the OBIEE Web Service API to consume data from the BI Server. I am able to XMLViewService and the WebCatalogService just fine, but I can't quite get the HtmlViewService to properly render a report in the Java app. The report just shows the spinning loader, but never actually renders the report. I'm pretty sure it has to do with the fact that the Java app and the BI Server are on different domains. This is what the API documentation says:
In situations where Oracle BI Web Services and the third-party Web server do not belong to the same Domain Name Service (DNS) domain, users may get JavaScript errors related to browser security constraints for cross-domain scripting. To avoid these issues, use the setBridge() method to modify callback URLs to point to the third-party Web server. Be aware that a Web component executed by the third-party Web server to re-route requests to Oracle BI Web Services is not provided. This function would need to be fulfilled by the third-party application.
Several years ago, I did this same type of integration using .NET/C# and ran in the the same issue because the .NET app and the BI Server were on different domains. As a result, I had to create an HTTP Handler (.ashx file) as well as use the setBridge() method to to solve the issue.
The challenge that I'm having is that I can't find a servlet bridge example for Java. And I'm not too confident in porting the .NET/.ASHX code to a Java servlet/bridge. Does anyone have any code examples or direction they could provide to point me in the right direction? Here's a snippet of code to show you what I'm doing to pull back the report data:
// define report path
ReportRef reportRef = new ReportRef();
reportRef.setReportPath(reportFolder + "/" + reportName);
// set page params
StartPageParams pageParams = new StartPageParams();
pageParams.setDontUseHttpCookies(true);
// set report params
String pageId = htmlService.startPage(pageParams, sawSessionId);
String reportId = pageId + reportName;
htmlService.addReportToPage(pageId, reportId, reportRef, null, null, null, sawSessionId);
// get report html
StringBuffer reportHtml = new StringBuffer();
reportHtml.append(htmlService.getHtmlForReport(pageId, reportId, sawSessionId));
// return html
return reportHtml.toString();
This is the error that is coming back in the browser:
XMLHttpRequest cannot load http://myobiserver.com/analytics/saw.dll?ajaxGo. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://myjavaapp.com' is therefore not allowed access.

Using the BridgeServlet from link (http://pastebin.com/NibVnBLb) posted in previous answer did not work for us. In our web portal, embedding Oracle BI dashboard using BridgeServlet above, redirected us to OBI login page and console log showed incorrect resources(js/css) web links (local URL instead of OBIEE URL's).
Instead we used this class (with some minor adjustments) https://gist.github.com/rafaeltuelho/9376341#file-obieehttpservletbridge-java.

Unit testing using MockMultipartHttpServletRequest (throws NullPointerException in ItemInputStream.makeAvailable)

I've written a transformer class that takes an HttpServletRequest and transforms it into another type that holds a pointer to the InputStream from the servlet request. (The idea is to abstract the incoming transport protocol from the request handling, so I could also write a similar transformer from FTP, for instance.)
Now I'm trying to write a unit test for this, and I'm having problems. I've managed to figure out the correct boilerplate to create a valid Multipart HTTP request (using the Spring classes MockMultipartHttpServletRequest and MockMultipartFile), but now I get a NullPointerException in the initialize() method of my UploadRequest class. I'm guessing the problem is that somehow the stream inside the MockMultipartHttpServletRequest isn't being initialized correctly, but I can't figure out what I should do differently.
Any suggestions would be gratefully accepted!

Here's an abbreviated version of my transformer class:
public class UploadRequest {
private Map<String, String> params;
private InputStream strIn;
private Logger Log = Logger.getLogger(UploadRequest.class.getName());
public UploadRequest()
{
params = new HashMap<String, String>();
}
public void initialize(HttpServletRequest sRequest,
ServletFileUpload upload)
throws IOException, FileUploadException
{
Enumeration<String> paramNames = sRequest.getParameterNames();
while (paramNames.hasMoreElements()) {
String pName = paramNames.nextElement();
params.put(pName, sRequest.getParameter(pName));
}
params.put("request_uri", sRequest.getRequestURI());
FileItemIterator iter = upload.getItemIterator(sRequest);
while (iter.hasNext()) {
FileItemStream item = iter.next();
try {
if (!item.isFormField()) {
// Skip form fields
params.put("original_file_name", item.getName());
strIn = item.openStream();
}
} catch (IOException ex) {
Log.severe("File uploading exception: " + ex.getMessage());
throw ex;
}
}
}
And here's the unit test:
import org.springframework.mock.web.MockMultipartHttpServletRequest;
import org.springframework.mock.web.MockMultipartFile;
import org.apache.commons.fileupload.servlet.ServletFileUpload;
// etc.... other imports
#RunWith(JMock.class)
public class UploadRequestTest {
private UploadRequest upRequest;
#Before
public void setUp()
{
context.setImposteriser(ClassImposteriser.INSTANCE);
upRequest = new UploadRequest();
}
#Test
public void testCreateFromServletRequest()
throws IOException, FileUploadException
{
String text_contents = "hello world";
MockMultipartHttpServletRequest sRequest =
new MockMultipartHttpServletRequest();
sRequest.setMethod("POST");
String boundary = generateBoundary();
String contentType = "multipart/form-data; boundary="+boundary;
sRequest.setContentType(contentType);
sRequest.setRequestURI("/foo");
sRequest.addParameter("test_param","test_value");
sRequest.addFile(
new MockMultipartFile("file1","test_upload.txt","text/plain",
text_contents.getBytes()));
ServletFileUpload upload = new ServletFileUpload();
assertTrue(upload.isMultipartContent(sRequest));
upRequest.initialize(sRequest, upload);
}
}

I have the same issue and I googled but no answer. I plugged in the source code from the library, You need to send content, whatever. The library might need to check if it is null in the skip method
MockMultipartHttpServletRequest request
request.setContent("whatever".getBytes());
Posted here for others

Add boundary condition
Generate contents as follows
MockMultipartHttpServletRequest request =
this.generateMockMultiPartHttpServletRequest(true);
MockMultipartFile mockMultipartFile = null;
try {
request.setContentType("multipart/form-data; boundary=-----1234");
request.setCharacterEncoding("text/plain");
String endline = "\r\n";
String bondary = "-----1234";
String textFile = this.encodeTextFile("-----1234", "\r\n", "file","test.csv",
"text/UTF-8", FileUtils.readFileToString((new File(csvFilePath)), "UTF-8"));
StringBuilder content = new StringBuilder(textFile.toString());
content.append(endline);
content.append(endline);
content.append(endline);
content.append("--");
content.append(bondary);
content.append("--");
content.append(endline);
request.setContent(content.toString().getBytes());
request.setMethod("POST");
mockMultipartFile = new MockMultipartFile("file",
FileUtils.readFileToByteArray(new File(csvFilePath)));
} catch (Exception e1) {
e1.printStackTrace();
}
request.addFile(mockMultipartFile);
Function to encode text
private String encodeTextFile(String bondary, String endline, String name,
String filename, String contentType, String content) {
final StringBuilder sb = new StringBuilder(64);
sb.append(endline);
sb.append("--");
sb.append(bondary);
sb.append(endline);
sb.append("Content-Disposition: form-data; name=\"");
sb.append(name);
sb.append("\"; filename=\"");
sb.append(filename);
sb.append("\"");
sb.append(endline);
sb.append("Content-Type: ");
sb.append(contentType);
sb.append(endline);
sb.append(endline);
sb.append(content);
return sb.toString();
}

I went through the same problem, after searching lot I got this post in which I answered with code that solved my problem.
The Shriprasad's solution works well for text file. But I had some problems with binary files.
