I am getting "no ":" in url blackberry" exception when I try to hit web service.
My url is like "http://url/MobileWrapper/action_name.do"
String redemptionUrl = "http://test.TTMF.com/MobileWrapper/reconfirm.do";
HttpConnection httpConn = null; DataOutputStream dataOS = null;
redemptionUrl = redemptionUrl+ ";deviceside=true";
httpConn = (HttpConnection) Connector.open(redemptionUrl);
Check your generated URL. It must be an invalid URL. Do debug or System.out.print(..).
To make a connection you have to do some common tasks, such as
White Space removal from URL.
Encode unwanted characters in URL with their HTML equivalent code.
Append appropriate connection parameter to the URL depending on connectivity support available on the device.

I try to convert Html to PDF use "HtmlToPdf" nuget , It was work fine on local test but when i upload site to host i get this error :
Conversion error: Authentication error.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Exception: Conversion error: Authentication error.
This is my Convert method Code
[AllowAnonymous]
public ActionResult Convert(int id)
{
HtmlToPdf converter = new HtmlToPdf();
var context = System.Web.HttpContext.Current;
string baseUrl = context.Request.Url.Host + ":"+context.Request.Url.Port + "/Doctor/DietTherapy/LineRegimePrint/";
PdfDocument doc = converter.ConvertUrl(baseUrl + id);
// save pdf document
byte[] pdf = doc.Save();
// close pdf document
doc.Close();
// return resulted pdf document
FileResult fileResult = new FileContentResult(pdf, "application/pdf");
fileResult.FileDownloadName = "Document.pdf";
return fileResult;
}
How can i authorize user for this convert ?
It sounds like you just need to authenticate the request being made by the PDF library. For example, if it's using Basic HTTP Authentication:
HtmlToPdf converter = new HtmlToPdf();
converter.Options.Authentication.Username = "some username";
converter.Options.Authentication.Password = "some password";
// the rest of your code...
The linked documentation also contains examples for other authentication methods.
Did you check to see if you're getting the proper value on this line of code (when running on host server)?
string baseUrl = context.Request.Url.Host + ":"+context.Request.Url.Port + "/Doctor/DietTherapy/LineRegimePrint/";
While your development machine's IIS Express uses Anonymous Authentication, your hosting server is probably using Windows Authentication or other kinds. Check the IIS Managers to see the difference.
SelectPDF's library somehow creates a separate process to perform the HtmlToPdf conversion, which is outside the IUser, and therefore, the server asks for authentication.
For Windows Authentication setting, you may just use a generic user login account for this purpose and populate the required properties as mentioned in above thread and all would be fine.
converter.Options.Authentication.Username = "WindowsUser";
converter.Options.Authentication.Password = "WindowsPassword";
When using HttpClient, I have read examples (such as this example) that uses DefaultRequestHeaders to set the content type (such as "application/json") of a Post request.
I tried to do something like this, but it failed. The API I am sending requests complained that it was sent an "unsupported type" (which it says when the content type is not set to json).
After that I added one line and I solved the issue (you can see the line in the code below commented).
My question is why is this line necessary? And if I include this line (that is setting the content type of the content) doesn't that make the "default request header" setting unnecessary. What is this "default request header" doing if anything?
(I actually tried and commented the lines related to DefaultRequestHeaders and it worked without problem. So what is DefaultRequestHeaders good for?)
My code is :
// Get the bytes for the request, should be pre-escaped
byte[] bytes = Encoding.UTF8.GetBytes(jsonEmployeeData);
client.BaseAddress = new Uri("the address here");
// client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(
new MediaTypeWithQualityHeaderValue("application/json"));
client.DefaultRequestHeaders.Add("customHeader", "blahblahblah");
ByteArrayContent byteContent = new ByteArrayContent(bytes); //Make a new instance of HttpContent (an abstract class that can't be instantiated)
//THIS is the solution
//byteContent.Headers.ContentType = new MediaTypeWithQualityHeaderValue("application/json"); //If I UNCOMMENT THIS, IT WORKS!!
try
{
HttpResponseMessage response = await client.PostAsync("staff", byteContent);
Console.WriteLine(response.ToString());
}
catch (Exception ex)
{
Console.WriteLine("Something happened, oopps!" + ex.Message);
}
Console.WriteLine("Press any key");
Console.ReadLine();
client is a HttpClient by the way.
The API you called needs the request content is application/json format, so you have to specify this format in your content. That's why that line of code is the one you need:
byteContent.Headers.ContentType = new MediaTypeWithQualityHeaderValue("application/json");
About the line:
client.DefaultRequestHeaders.Accept.Add(
new MediaTypeWithQualityHeaderValue("application/json"))
This is request Accept header, it means the content type of response which you expect the server return to you. (You can expect server returns another content type like text/plain,...). Hope this helps!
I want to download a file from a server via the internet with a BlackBerry app.
It is not important which protocol is used: FTP, HTTP or something else would be fine. I just need the user to click "download" button and then the app downloads this file from a server.
I have no idea how it can be done. I have tried a few solutions. In one I need a HttpConnectorFactory but this is not in my API.
I have searched for an answer to my question for days, but I haven't found a solution that works.

I am trying to consume SOAP response xml by passing request xml in a string, using BlackBerry Java plugin for Eclipse. I have been struck on this for the past two days looking for a way to solve it.
I have attached the sample code below.
public String CheckXml()
{
final String requestXml="<SOAP:Envelope xmlns:SOAP=\"http://schemas.xmlsoap.org/soap/envelope/\"><header xmlns=\"http://schemas.cordys.com/General/1.0/\"></header><SOAP:Body><authenticateAgainstOID xmlns=\"http://schemas.cordys.com/OIDAuthentication\"><stringParam>HEMANTS_MUM013</stringParam><stringParam1>TATA2012</stringParam1></authenticateAgainstOID></SOAP:Body></SOAP:Envelope>";
final String HOST_ADDRESS = "http://xyz.com/cordys/com.eibus.web.soap.Gateway.wcp?organization=o=B2C,cn=cordys,cn=cbop,o=tatamotors.com&SAMLart=MDFn+8e5dRDaRMRIwMY7nI84eEccbx+lIiV0VhsOQ7u+SKG6n5+WNB58";
String result="";
try {
HttpConnection url=(HttpConnection)Connector.open(HOST_ADDRESS);
url.setRequestProperty("Content-Type", "text/xml");
url.setRequestMethod(HttpConnection.GET);
OutputStreamWriter writer=new OutputStreamWriter(url.openOutputStream());
writer.write(requestXml);
writer.flush();
writer.close();
StringBuffer buffer1=new StringBuffer();
InputStreamReader reader=new InputStreamReader(url.openInputStream());
StringBuffer buffer=new StringBuffer();
char[] cbuf=new char[2048];
int num;
while (-1 != (num = reader.read(cbuf))) {
buffer.append(cbuf, 0, num);
}
String result1 = buffer.toString();
} catch (Exception e) {
System.out.println(e);
}
return result;
}
I think the main issue that you aren't asking http. getResponseCode(). I think BB doesn't do any interaction until you call it.
I would also be careful with this code on the real devices. Search for correct opening connection on the BlackBerries.
I noticed that you are not including the SoapAction header in the request.
SOAP Web services usually have a fixed URL, and the differents methods are selected with the SoapAction header. You can check the header by opening the WSDL in a browser and inspecting the format for the method you want to invoke.
Once you know which action to select, set it as a regular http header:
url.setRequestProperty("SOAPAction", <your action here>);
Another source of problems in your code is that you are using the old HttpConnection class that requires appending a suffix to the URL depending on the transport type (MDS, BIS, Wi-Fi, etc). You don't need to use this legacy class unless you are targeting OS 4.5 and lower. So have a look at ConnectionFactory class, which is much easier to use. It is available since OS 5.0.
I am trying to integrate upload of arbitrary files to Google Docs into an existing application. This used to work before using resumable upload became mandatory. I am using Java client libraries.
The application is doing the upload in 2 steps:
- get the resourceId of the file
- upload the data
To get the resourceId I am uploading a 0-size file (i.e. Content-Length=0). I am passing ?convert=false in the resumable URL (i.e. https://docs.google.com/feeds/upload/create-session/default/private/full?convert=false).
I am passing "application/octet-stream" as content-type. This seems to work, though I do get different resourcesIds - "file:..." resourceIds for things like images, but "pdf:...." resourceIds for PDFs.
The second step constructs a URL based on the resourceId obtained previously and performs a search (getEntry). The URL is in the form of https://docs.google.com/feeds/default/private/full/file%3A.....
Once the entry is found the ResumableGDataFileUploader is used to update the content (0-byte file) with the actual data from the file being uploaded. This operation fails with 401 Unauthorized response when building ResumableGDataFileUploader instance.
I've tried with ?convert=false as well as ?new-revision=true and both of these at the same time. The result is the same.
The relevant piece of code:
MediaFileSource mediaFile = new MediaFileSource(
tempFile, "application/octet-stream");
final ResumableGDataFileUploader.Builder builder =
new ResumableGDataFileUploader.Builder(client, mediaFile, documentListEntry);
builder.executor(MoreExecutors.sameThreadExecutor());
builder.requestType(ResumableGDataFileUploader.RequestType.UPDATE);
// This is where it fails
final ResumableGDataFileUploader resumableGDataFileUploader = builder.build();
resumableGDataFileUploader.start();
return tempFile.length();
The "client" is an instance of DocsService, configured to use OAuth. It is used to find "documentListEntry" immediately before the given piece of code.
I had to explicitly specify request type, since it seems the client library code contains a bug causing NullPointerException for "update existing entry" case.
I have a suspicion that the issue is specifically in the sequence of actions (upload 0-byte file to get the resourceId, then update with actual file) but I can't figure out why it doesn't work.
Please help?
This code snippet works for me using OAuth 1.0 and OAuth 2.0:
static void uploadDocument(DocsService client) throws IOException, ServiceException,
InterruptedException {
ExecutorService executor = Executors.newFixedThreadPool(10);
File file = new File("<PATH/TO/FILE>");
String mimeType = DocumentListEntry.MediaType.fromFileName(file.getName()).getMimeType();
DocumentListEntry documentEntry = new DocumentListEntry();
documentEntry.setTitle(new PlainTextConstruct("<DOCUMENT TITLE>"));
int DEFAULT_CHUNK_SIZE = 2 * 512 * 1024;
ResumableGDataFileUploader.Builder builder =
new ResumableGDataFileUploader.Builder(
client,
new URL(
"https://docs.google.com/feeds/upload/create-session/default/private/full?convert=false"),
new MediaFileSource(file, mimeType), documentEntry).title(file.getName())
.requestType(RequestType.INSERT).chunkSize(DEFAULT_CHUNK_SIZE).executor(executor);
ResumableGDataFileUploader uploader = builder.build();
Future<ResponseMessage> msg = uploader.start();
while (!uploader.isDone()) {
try {
Thread.sleep(100);
} catch (InterruptedException ie) {
throw ie; // rethrow
}
}
DocumentListEntry uploadedEntry = uploader.getResponse(DocumentListEntry.class);
// Print the document's ID.
System.out.println(uploadedEntry.getId());
System.out.println("Upload is done!");
}
