I am trying to call HTTP request with network credential in blackberry. i have already implement on Java, Android it's working fine but not working on blackberry. Following step i have done in blackberry.
For set Network credential i have added three following jar.
commons-codec-1.6.jar
commons-httpclient-3.0.1.jar
commons-logging-1.1.1.jar
add this jar files are in blackberry project.
Following sample Code that work fine in Core Java.
try{
HttpClient client = new HttpClient();
GetMethod get = new GetMethod("http://www.google.com");
get.setDoAuthentication( true );
try {
int status = client.executeMethod( get );
System.out.println(status + "\n" + get.getResponseBodyAsString());
} finally {
get.releaseConnection();
}
}catch(Exception e){
System.out.println("Error:>>>>>>"+e);
}
Now there are not error on code but whenever try to click on application icon error face like "error starting appName: Module 'commons-httpclient-3.0.1' not found"
Can any one suggest what's this error say.
BB does not support HttpClient. But it does support J2ME's HttpConnection and is quite similar to HttpClient, so you can easily adjust with it. Here's some sample code to get you started:
try{
HttpConnection mConn = (HttpConnection)Connector.open(urlToPost);
mConn.setRequestMethod(HttpConnection.POST);
mConn.setRequestProperty("IF-Modified-Since", "20 Jan 2001 16:19:14 GMT");
mConn.setRequestProperty("User-Agent","Profile/MIDP-1.0 Configuration/CLDC-1.0");
mConn.setRequestProperty("Content-Language", "en-CA");
//---------------------------------------------------
mConn.setRequestProperty("User",usr);
mConn.setRequestProperty("pass",pass);
//---------------------------------------------------
catch(Exception e){//---handle your exceptions---//}
} finally {
mConn.close();//don't forget to close connections, only a limited number are available
}
This is a good article for beter understanding.

I am trying to play Widevine encrypted content on an Android TV application using Exoplayer. I have my video URL which is served from a CDN and acquired with a ticket. I have my widevine license URL, a ticket and a auth token for the license server.
I am creating a drmSessionManager, putting the necessary headers needed by the license server as follows:
UUID drmSchemeUuid = C.WIDEVINE_UUID;
mediaDrm = FrameworkMediaDrm.newInstance(drmSchemeUuid);
static final String USER_AGENT = "user-agent";
HttpMediaDrmCallback drmCallback = new HttpMediaDrmCallback("my-license-server", new DefaultHttpDataSourceFactory(USER_AGENT));
keyRequestProperties.put("ticket-header", ticket);
keyRequestProperties.put("token-header", token);
drmCallback.setKeyRequestProperty("ticket-header", ticket);
drmCallback.setKeyRequestProperty("token-header", token);
new DefaultDrmSessionManager(drmSchemeUuid, mediaDrm, drmCallback, keyRequestProperties)
After this Exoplayer handles most of the stuff, the following breakpoints are hit.
response = callback.executeKeyRequest(uuid, (KeyRequest) request);
in class DefaultDrmSession
return executePost(dataSourceFactory, url, request.getData(), requestProperties) in HttpMediaDrmCallback
I can observe that everything is fine till this point, the URL is correct, the headers are set fine.
in the following piece of code, I can observe that the dataSpec is fine, trying to POST a request to the license server with the correct data, but when making the connection the response code returns 405.
in class : DefaultHttpDataSource
in method : public long open(DataSpec dataSpec)
this.dataSpec = dataSpec;
this.bytesRead = 0;
this.bytesSkipped = 0;
transferInitializing(dataSpec);
try {
connection = makeConnection(dataSpec);
} catch (IOException e) {
throw new HttpDataSourceException("Unable to connect to " + dataSpec.uri.toString(), e,
dataSpec, HttpDataSourceException.TYPE_OPEN);
}
try {
responseCode = connection.getResponseCode();
responseMessage = connection.getResponseMessage();
} catch (IOException e) {
closeConnectionQuietly();
throw new HttpDataSourceException("Unable to connect to " + dataSpec.uri.toString(), e,
dataSpec, HttpDataSourceException.TYPE_OPEN);
}
When using postman to make a request to the URL, a GET request returns the following body with a response code of 405.
{
"Message": "The requested resource does not support http method 'GET'." }
a POST request also returns response code 405 but returns an empty body.
In both cases the following header is also returned, which I suppose the request must be accepting GET and POST requests.
Access-Control-Allow-Methods →GET, POST
I have no access to the configuration of the DRM server, and my contacts which are responsible of the DRM server tells me that POST requests must be working fine since there are clients which have managed to get the content to play from the same DRM server.
I am quite confused at the moment and think maybe I am missing some sort of configuration in exoplayer since I am quite new to the concept of DRMs.
Any help would be greatly appreciated.
We figured out the solution. The ticket supplied for the DRM license server was wrong. This works as it is supposed to now and the content is getting played. Just in case anyone somehow gets the same problem or is in need of a basic Widevine content playing code, this works fine at the moment.
Best regards.

I am working on a project which need to consume an enterprise Web API(Https) and display the data on Win 10 live tile, it’s an UWP application.
But I found it only works when I ran it in IDE(Visual Studio 2015 debug mode) .
When I created a package for this app and run it by powershell for installation, request.GetResponseAsync method throws exception “The login request was denied”.
I tried to check Enterprise Authentication and Private Networks(Client & Server) options in Package.appxmanifest. But there was no effect.
Any idea how to make it work normally? Thanks.
I recently created a proof of concept console application using SignalR (self host). It worked a treat for our use. The client connected fine and I was able to send updates from the server to the client. Lovely!
I've now transferred the code from the Console application to a winforms application for a prettier UI. Now that same client won't connect to the server yet it will still connect to the old Console version.
Winforms code:
string url = "http://localhost:8080";
using (WebApp.Start(url))
{
// Let the app know the server is up
}
Console code:
string url = "http://localhost:8080";
using (WebApp.Start(url))
{
Console.WriteLine("Server running on {0}", url);
Console.ReadLine();
}
Client connection code:
if (!connected)
{
int i = 0;
// Try 3 times
while (i <= 2)
{
try
{
string server = Properties.Settings.Default.Server + ":" + Properties.Settings.Default.PortNumber.ToString();
connection = new HubConnection(server);
connection.StateChanged += connection_StateChanged;
hub = connection.CreateHubProxy("MyHub");
connection.Start().Wait();
hub.On<string>("addMessage", param => { UpdateAlarmStatus(param); });
return true;
}
catch (Exception)
{
i++;
}
}
return false;
}
else
{
return true;
}
The error the client is reporting is:
Exception:Thrown: "No connection could be made because the target machine actively refused it" (System.Net.Sockets.SocketException)
A System.Net.Sockets.SocketException was thrown: "No connection could be made because the target machine actively refused it"
Time: 25/01/2015 15:09:23
Thread:Worker Thread[8232]
Why would the target machine (localhost) refuse itself which the Console version doesn't? I've been looking at the code over and over and I cannot see where I'm going wrong. Can anyone point me in the right direction please?
Thank you for reading.
Paul.
I suspect this is an issue with the configuration of your machine/infrastructure rather than the code itself, which looks fine at first glance.
Have you checked the console debug output in Visual Studio? I recently encountered an issue with similar symptoms and that was what gave me the initial clue to keep investigating. In my particular case, an exception was written to the console debug output that didn't make it to the client.
SignalR will normally negotiate with the server automatically to determine the best transport method to use. In a .NET client, the available options are LongPollingTransport, ServerSentEventsTransport and WebSocketTransport. So for some reason, your console app can use at least one of those methods, whereas your WinForms client cannot.
You can perhaps enable tracing to give you more information to work with. To do this, enter the below before you create the hub proxy:
hubConnection.TraceLevel = TraceLevels.All;
hubConnection.TraceWriter = Console.Out;

I am trying to figure out how to send an email from a Flash Mobile (smartphones: blackberries, iphones, androids) app using mxml and Flash using Flash Builder 4.6. My boss told me to find out if it is possible. So far, I have been doing a lot of searching around on the internet for an answer.
I found this website: http://www.bytearray.org/?p=27, that has some classes for sending email in flash, but #1, I don't know if they work in Mobile apps, and #2, I can't find any instructions or tutorials on how to use the classes to send a simple email.
I downloaded the package from the site and imported into my project, where I am trying to send the code. But without sample code on how to simply send an email, I am not entirely sure what all do, and nor am I sure how to determine things like what port number to construct the SMTPMailer object (the SMTPMailer object is included in that package, and it takes a host string and a port number integer in it's constructor), right now I am trying 80 or 8080 for the port number, and I've tried localhost and one of our server computers, 198.162.1.109 for the host.
Anyway, I keep getting this error: Error #2044: Unhandled IOErrorEvent:. text=Error #2031: Socket Error.
Here is some of my sample code:
[Bindable]
private var mailer : SMTPMailer;
private function init() : void {
tbPass.displayAsPassword = true;
}
protected function btnClick_email(toAddress : String, fromAddress : String, pass : String) : void {
mailer = new SMTPMailer("198.168.1.109", 8080);
mailer.addEventListener(SMTPEvent.MAIL_SENT, onMailSent);
mailer.addEventListener(SMTPEvent.MAIL_ERROR, onMailError);
mailer.addEventListener(SMTPEvent.CONNECTED, onConnected);
mailer.addEventListener(SMTPEvent.DISCONNECTED, onDisconnected);
mailer.connect("hotmail.com", 8080);
mailer.authenticate(toAddress, pass);
mailer.sendHTMLMail(fromAddress, toAddress, "Subect", "Message");
}
private function onMailSent() : void {
lblEmailResult.text = "Sent Mail";
}
private function onMailError() : void {
lblEmailResult.text = "Error";
}
private function onConnected() : void {
lblEmailResult.text = "Connected";
}
private function onDisconnected() : void {
lblEmailResult.text = "Disconnected";
}
I would suggest using a back-end service to send emails, it is same as connecting to a SMTP mail server but it is more flexible.
That being said, it should work, the error you are getting is related to your host IP, are you sure you have SMTP server running on "198.168.1.109:8080"?
First check if you can send mails from it before trying to do it trough Flex, if that is OK, then you should double check socket policy files:

Hope that helps
Can't you just use navigateToURL() for this?
Ie:
var request:URLRequest("mailto:someone#somewhere.com");
navigateToURL(request);
That's all - 2 lines :)
I've accomplished this in a commercial app I worked on. We used a native extension found in distriqt's set of tools. Google them. The full suite of tools is cheap, though if you have any issues, do not expect a quick reply. Their message tool is what you are looking for, and it is easy to use.
I am using the HTTP Connection in the following way:
HttpConnection _httpConnection = null;
try {
_httpConnection = (HttpConnection)Connector.open(_url);
} catch(Exception e) { }
byte [] postDataBytes = _postData.getBytes();
_httpConnection.setRequestMethod(HttpConnection.POST);
_httpConnection.setRequestProperty("User-Agent","Profile/MIDP-2.0 Configuration/CLDC-1.0");
_httpConnection.setRequestProperty("Content-Language", "en-US");
_httpConnection.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
_httpConnection.setRequestProperty("Connection", "close");
_httpConnection.setRequestProperty("Content-Length", Integer.toString(_postData.getBytes().length));
os = _httpConnection.openOutputStream();
os.write(postDataBytes);
os.flush();
This HTTP Connection requires parameters to successfully open. For example on a WIFI network, it requires the ";deviceside=true;interface=wifi" to be added to the URL.
The problem is for the EDGE connection. Each country requires different parameters to be added. For example in lebanon it requires ";deviceside=false" but in KSA if i add this parameter the connection will not open. In USA it needs different types of parametes. The question is how to establish an HTTP connection for all the countries with the same parameters. So that the application will successfully have an internet connection no matter where it is downloaded.
Welcome to the confusing world of network transports on BlackBerry! You will want to start with the article Connecting your BlackBerry - http and socket connections to the world.
Here is a simple example for "just give me a connection" (note, you will need to add appropriate error handling; also, myURL in the code below should have no connection descriptor info appended to it):
ConnectionFactory factory = new ConnectionFactory();
ConnectionDescriptor descriptor = factory.getConnection(myURL);
if (descriptor != null) {
_httpConnection = (HttpConnection) descriptor.getConnection();
...
}
Try using to use the method reffered in this link melick-rajee.blogspot.com and use it like
_url = "http://www.example.com";
_httpConnection = (HttpConnection)Connector.open(_url + getConnectionString());
You will have to sign the application to use this else the application will show exception.
To sign your application just go here Code Signing Keys
To use the connectionFactory, seems you need to set BisBOptions.
Try this:
connFact = new ConnectionFactory();
connFact.setTransportTypeOptions(TransportInfo.TRANSPORT_BIS_B,
new BisBOptions("mds-public"));
