I have the following code in groovy
HTTPBuilder http = new HTTPBuilder("https://ronna-afghan.harmonieweb.org/_layouts/searchrss.aspx")
http.request(Method.GET, groovyx.net.http.ContentType.XML) {
// set username and password for basic authentication
// set username and password for basic auth
//http.auth.basic(ConfigurationHolder.config.passportService.userName,
// ConfigurationHolder.config.passportService.password)
headers.'User-Agent' = 'Mozilla/5.0'
uri.query = [k:'execution']
// response handler for a success response code:
response.success = {resp, xml ->
println resp.statusLine
log.debug "response status: ${resp.statusLine}"
log.debug xml.toString()
}
// handler for any failure status code:
response.failure = {resp ->
log.error " ${resp.statusLine.statusCode} : ${resp.statusLine.reasonPhrase}"
}
}
when I run the code, it doesn't give me the rss feed which I'm suppose to get
When I have the same code in java
try {
// Create a URLConnection object for a URL
URL oracle = new URL(
"https://ronna-afghan.harmonieweb.org/_layouts/srchrss.aspx?k=execution&count=1&format=rss");
URLConnection yc = oracle.openConnection();
BufferedReader in = new BufferedReader(new InputStreamReader(
yc.getInputStream()));
String inputLine;
while ((inputLine = in.readLine()) != null) {
System.out.println(inputLine);
in.close();
}
} catch (Exception e) {
e.printStackTrace();
}
}
it returns the xml Rss. I can't figure what the issue might be. Everything looks okay to me in the groovy code and also the Http return code is 200.
The code that you have described in Java is the equivalent of the following code in Groovy:
def oracle = "https://ronna-afghan.harmonieweb.org/_layouts/srchrss.aspx?k=execution&count=1&format=rss".toURL().text

I am exploring Microsoft Computer Vision's Read API (asyncBatchAnalyze) for extracting text from images. I found some sample code on Microsoft site to extract text from images asynchronously.It works in following way:
1) Submit image to asyncBatchAnalyze API.
2) This API accepts the request and returns a URI.
3) We need to poll this URI to get the extracted data.
Is there any way in which we can trigger some notification (like publishing an notification in AWS SQS or similar service) when asyncBatchAnalyze is done with image analysis?
public class MicrosoftOCRAsyncReadText {
private static final String SUBSCRIPTION_KEY = “key”;
private static final String ENDPOINT = "https://computervision.cognitiveservices.azure.com";
private static final String URI_BASE = ENDPOINT + "/vision/v2.1/read/core/asyncBatchAnalyze";
public static void main(String[] args) {
CloseableHttpClient httpTextClient = HttpClientBuilder.create().build();
CloseableHttpClient httpResultClient = HttpClientBuilder.create().build();;
try {
URIBuilder builder = new URIBuilder(URI_BASE);
URI uri = builder.build();
HttpPost request = new HttpPost(uri);
request.setHeader("Content-Type", "application/octet-stream");
request.setHeader("Ocp-Apim-Subscription-Key", SUBSCRIPTION_KEY);
String image = "/Users/xxxxx/Documents/img1.jpg";
File file = new File(image);
FileEntity reqEntity = new FileEntity(file);
request.setEntity(reqEntity);
HttpResponse response = httpTextClient.execute(request);
if (response.getStatusLine().getStatusCode() != 202) {
HttpEntity entity = response.getEntity();
String jsonString = EntityUtils.toString(entity);
JSONObject json = new JSONObject(jsonString);
System.out.println("Error:\n");
System.out.println(json.toString(2));
return;
}
String operationLocation = null;
Header[] responseHeaders = response.getAllHeaders();
for (Header header : responseHeaders) {
if (header.getName().equals("Operation-Location")) {
operationLocation = header.getValue();
break;
}
}
if (operationLocation == null) {
System.out.println("\nError retrieving Operation-Location.\nExiting.");
System.exit(1);
}
/* Wait for asyncBatchAnalyze to complete. In place of this wait, can we trigger any notification from Computer Vision when the extract text operation is complete?
*/
Thread.sleep(5000);
// Call the second REST API method and get the response.
HttpGet resultRequest = new HttpGet(operationLocation);
resultRequest.setHeader("Ocp-Apim-Subscription-Key", SUBSCRIPTION_KEY);
HttpResponse resultResponse = httpResultClient.execute(resultRequest);
HttpEntity responseEntity = resultResponse.getEntity();
if (responseEntity != null) {
String jsonString = EntityUtils.toString(responseEntity);
JSONObject json = new JSONObject(jsonString);
System.out.println(json.toString(2));
}
} catch (Exception e) {
System.out.println(e.getMessage());
}
}
}
There is no notification / webhook mechanism on those asynchronous operations.
The only thing that I can see right know is to change the implementation you mentioned by using a while condition which is checking regularly if the result is there or not (and a mechanism to cancel waiting - based on maximum waiting time or number of retries).
See sample in Microsoft docs here, especially this part:
// If the first REST API method completes successfully, the second
// REST API method retrieves the text written in the image.
//
// Note: The response may not be immediately available. Text
// recognition is an asynchronous operation that can take a variable
// amount of time depending on the length of the text.
// You may need to wait or retry this operation.
//
// This example checks once per second for ten seconds.
string contentString;
int i = 0;
do
{
System.Threading.Thread.Sleep(1000);
response = await client.GetAsync(operationLocation);
contentString = await response.Content.ReadAsStringAsync();
++i;
}
while (i < 10 && contentString.IndexOf("\"status\":\"Succeeded\"") == -1);
if (i == 10 && contentString.IndexOf("\"status\":\"Succeeded\"") == -1)
{
Console.WriteLine("\nTimeout error.\n");
return;
}
// Display the JSON response.
Console.WriteLine("\nResponse:\n\n{0}\n",
JToken.Parse(contentString).ToString());
I am stuck getting a failure back from my request. This works in postman but when trying in java, it fails every way I try it. Sample code below along with the response I get. I am able to send an HTTPPost to this webservice successfully using httpsurlconnection and outputstreamwriter but when trying to convert this to a GET without any that are not in the URL itself, it fails. Any help is very appreciated!!
//print out the encoded values
data.addToLog( “sha256hex: “, sha256hex);
data.addToLog( “xauth: “, xauth);
StringBuilder sb = new StringBuilder();
String baseurl = “https://” + apihost + endpoint + “?personID=” + personid;
data.addToLog( “BaseURL: “, baseurl);
//print out the JSON search request
try {
URL myurl = new URL(null, baseurl , new sun.net.www.protocol.https.Handler() );
HttpsURLConnection con = (HttpsURLConnection )myurl.openConnection();
con.setSSLSocketFactory(new TSLSocketConnectionFactory());
con.setRequestProperty(“X-Timestamp”, tsparam);
con.setRequestProperty(“X-Nonce”, nonce64);
con.setRequestProperty(“X-Authorization”, xauth);
con.setRequestProperty(“X-Test-Insecure”, “true”);
con.setRequestMethod(method);
con.setDoOutput(true);
con.setRequestProperty(“Content-Type”, “application/json;charset=utf-8”);
int responseCode = con.getResponseCode();
data.addToLog(“Response Code= “, con.getResponseCode() +”: “+ con.getResponseMessage());
if (responseCode == HttpURLConnection.HTTP_OK) { // success
BufferedReader in = new BufferedReader(new InputStreamReader(
con.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
// print result
//System.out.println(response.toString());
data.addToLog(“Response:”, response.toString() );
}
Log results:
PersonDetailsLookup,custom,Response Code= ,200: OK
PersonDetailsLookup,custom,Response:,{“serviceModel”:{“errorCode”:{“description”:”Unexpected System Error””value”:”500″}”errorMessage”:”API Invocation Failure – Unknown Error””severity”:{“description”:”FATAL””value”:”3″}}}
Figured it out! It was the content type and it needed to be changed to text instead of json:
con.setRequestProperty(“Content-Type”, “application/text;charset=utf-8”);
I have another question about a "JDWP Error: 21" logged: Unexpected JDWP Error 21
I am trying to parse some XML I gather from a servlet into a J2ME MIDlet with the code below. So far unsuccessfully, I think due to the JDWP error on my HttpConnection how ever the InputStream is filled with XML and once parsed everything inside the Document is null.
Has anyone got and ideas about the JDWP error, and also does that code look like it should work?
In MIDlet I am using JSR-172 API javax.xml.parsers.*.

I am tring to list all the management certificates in a windows azure subcription. And I tried with the following code. But it gives me an exception. And I could find that response is null and the exception message is "The remote server returned an error: (403) Forbidden."
Please help me with this. Msdn doesn't provide an example for this :(

using System.Xml.Linq;

public static void Runme()

string subscriptionId = "I used the subscription Id here";
try
{
ListManagementCertificates(subscriptionId, msVersion);
}
catch (Exception ex)
{
Console.WriteLine("Exception caught: ");
Console.WriteLine(ex.Message);
}
}
private static void ListManagementCertificates(string subscriptionId, string version)
{
string uriFormat = "https://management.core.windows.net/{0}/certificates";

request.Headers.Add("x-ms-version", version);
request.ContentType = "application/xml";
XDocument responseBody = null;
HttpStatusCode statusCode;
HttpWebResponse response;
try
{
response = (HttpWebResponse)request.GetResponse();
}
catch (WebException ex)
{
// GetResponse throws a WebException for 400 and 500 status codes
response = (HttpWebResponse)ex.Response;
}
statusCode = response.StatusCode;
if (response.ContentLength > 0)
{
using (XmlReader reader = XmlReader.Create(response.GetResponseStream()))
{
responseBody = XDocument.Load(reader);
}
}
response.Close();
if (statusCode.Equals(HttpStatusCode.OK))
{
XNamespace wa = "http://schemas.microsoft.com/windowsazure";
XElement storageServices = responseBody.Element(wa + "SubscriptionCertificates");
int mngmntCertificateCount = 0;
foreach (XElement storageService in storageServices.Elements(wa + "SubscriptionCertificate"))
{
string publicKey = storageService.Element(wa + "SubscriptionCertificatePublicKey").Value;
string thumbprint = storageService.Element(wa + "SubscriptionCertificateThumbprint").Value;
string certificateData = storageService.Element(wa + "SubscriptionCertificateData").Value;
string timeCreated = storageService.Element(wa + "TimeCreated").Value;
Console.WriteLine(
"Certificate[{0}]{1} SubscriptionCertificatePublicKey: {2}{1} SubscriptionCertificateThumbprint: {3}{1} certificateData{4}{1} timeCreated{5}{1}",
mngmntCertificateCount++, Environment.NewLine, publicKey, thumbprint, certificateData, timeCreated);
}
}
else
{
Console.WriteLine("List Management certificates returned an error:");
Console.WriteLine("Status Code: {0} ({1}):{2}{3}",
(int)statusCode, statusCode, Environment.NewLine,
responseBody.ToString(SaveOptions.OmitDuplicateNamespaces));
}
return;
}
}
Thanks it's working as I expected. I just add the following line and the Method 'GetCertificate(arg1)'
request.ClientCertificates.Add(GetCertificate(certThumbprint));
One more thing, in Msdn help guide there's a tag in respond body called
<TimeCreated>time-created</TimeCreated>
But the api responds not the TimeCreated its just created.
<Created> ..... </Created>
403 error means something wrong with your management certificate used to authenticate your Service Management API requests. I don't see you attaching a management certificate along with your request in your code. You may find this link useful for authenticating service management API requests: http://msdn.microsoft.com/en-us/library/windowsazure/ee460782.

I have a webdav function listed below:
The behavior is completely unexpected....
When I first run the function and pass a URL to a resource (folder in sharepoint) that does not exist, I get a 404 which is expected. I then use another function to create the resource using THE SAME credentials as in this method. No problems yet...
However on 2nd run, after the resource has been created - when I check if resource exists, now I get a 401.
Whats important to note here is that the same credentials are used to check for 401 and create folder, so clearly the credentials are fine...
So it must be something else.... All I want to do is check if a resource exists in SharePoint.... any ideas how to improve this function? Or any theory as to why its giving this 401...
private bool MossResourceExists(string url)
{
var request = (HttpWebRequest)WebRequest.Create(url);
request.Method = "HEAD";
// Create a new CredentialCache object and fill it with the network
// credentials required to access the server.
var myCredentialCache = new CredentialCache();
if (!string.IsNullOrEmpty(this.Domain ))
{
myCredentialCache.Add(new Uri(url),
"NTLM",
new NetworkCredential(this.Username , this.Password , this.Domain )
);
}
else
{
myCredentialCache.Add(new Uri(url),
"NTLM",
new NetworkCredential(this.Username , this.Password )
);
}
request.Credentials = myCredentialCache;
try
{
request.GetResponse();
return true;
}
catch (WebException ex)
{
var errorResponse = ex.Response as HttpWebResponse;
if (errorResponse != null)
if (errorResponse.StatusCode == HttpStatusCode.NotFound)
{
return false;
}
else
{
throw new Exception("Error checking if URL exists:" + url + ";Status Code:" + errorResponse.StatusCode + ";Error Message:" + ex.Message ) ;
}
}
return true;
}
The only clue I have is that when using http://mysite.com/mydoclib/mytoplevelfolder it works.... any sub folders automatically give 401's....
The thing is that you can't pass the whole url that includes folders to the CredentialCache.Add() method.
For example:
http://MyHost/DocumentLibrary/folder1/folder2 will not work as an Uri to the Add() method, but
http://MyHost/DocumentLibrary/ will work.
I would guess that the lack of permissioning capabilities on folder level in SharePoint is the reason for this. Or the way that otherwise SharePoint handles folders.
What you can do is to separate the parameters in your method to accept a base url (including document libraries / lists) and a folder name parameter.
The CredentialCache gets the base url and the request object gets the full url.
Another way is to use the
request.Credentials = System.Net.CredentialCache.DefaultCredentials;
credentials instead. And, if necessary, do an impersonation if you want to use another account than the executing one.
A third variation is to try with authentication type set to Kerberos instead of NTLM.
Here is my test code. I am able to reproduce the problem if I replace the problem with your code, and this code works for me.
static void Main(string[] args)
{
bool result = MossResourceExists("http://intranet/subtest/content_documents/", "testfolder/testfolder2");
}
private static bool MossResourceExists(string baseUrl, string folder)
{
string completeUrl = baseUrl + folder;
var request = (HttpWebRequest)WebRequest.Create(completeUrl);
request.Method = "HEAD";
// Create a new CredentialCache object and fill it with the network
// credentials required to access the server.
var myCredentialCache = new CredentialCache();
if (!string.IsNullOrEmpty(Domain))
{
myCredentialCache.Add(new Uri(baseUrl),
"NTLM",
new NetworkCredential(Username, Password, Domain)
);
}
else
{
myCredentialCache.Add(new Uri(baseUrl),
"NTLM",
new NetworkCredential(Username, Password)
);
}
request.Credentials = myCredentialCache;
//request.Credentials = System.Net.CredentialCache.DefaultCredentials;
try
{
WebResponse response = request.GetResponse();
return true;
}
catch (WebException ex)
{
var errorResponse = ex.Response as HttpWebResponse;
if (errorResponse != null)
if (errorResponse.StatusCode == HttpStatusCode.NotFound)
{
return false;
}
else
{
throw new Exception("Error checking if URL exists:" + completeUrl + ";Status Code:" + errorResponse.StatusCode + ";Error Message:" + ex.Message);
}
}
return true;
}
Hope this helps.
