• Problem with HttpConnection when it connects only not to wifi - java.io.IOException: Tunnel failed

  Hi all

  I develop an application that communicates with a database MySQL via PHP stored on the server scripts. Until today I've developed using the Simulator, and everything has been fine. I now started to test on a device and, while being connected to wifi, everything is still fine. However, the minute I turn off wifi and let the network provider, O2 UK, I get:

  "Request failed: reason: java.io.IOException: Tunnel failed".

  The source of the connection code is as follows:

     public void run() {
         // The following code will only build under JDE 4.5 and later
  
         try {
             String connectionParameters = "";
             // JDE 4.3 is required to get WLANInfo
             if (WLANInfo.getWLANState() == WLANInfo.WLAN_STATE_CONNECTED) {
                 // Connected to a WiFi access point
                 connectionParameters = ";interface=wifi";
             } else {
                 int coverageStatus = CoverageInfo.getCoverageStatus();
                 ServiceRecord record = getWAP2ServiceRecord();
                 if (record != null
                         // In JDE 4.5 CoverageInfo changed the name of
  COVERAGE_CARRIER to COVERAGE_DIRECT
                         // The constant value for both is the same,
  '1', so you can use that to avoid any
                         // dependency on JDE 4.5
                         && (coverageStatus & CoverageInfo.COVERAGE_DIRECT) ==
                         CoverageInfo.COVERAGE_DIRECT) {

         } catch (IOException ex) {
             screen.requestFailed(ex.toString());
         }
     }
  

  I scoured these forums and tried everything I can find. I tried different settings, including changing the APN settings both wap and mobile options for O2. Nothing seems to solve this problem.

  Any help would be appreciated!

  Thank you

  Jack

  OK, good news. Fixed. Thanks a lot for your answers. I would have understood the connection settings as they appear to have been the problem.

  I don't remember exactly which it generated, but I decided to try replacing it with the generator of connectionParameter above with the snippet connSuffix here:
  http://supportforums.BlackBerry.com/T5/Java-development/connecting-your-BlackBerry-http-and-socket-c...

  Worked like a dream, so I'm very indebted to all those who contributed to this. It now seems to work little matter the type of connection is available including BES.

  In case anyone is interested, however, I tried all combinations of settings APN bloody O2, but it came to nothing. I am disappointed that it was the connection settings I developed that a book by Apress, and I followed this particular part, Word for Word.

  Thank you all for the world of useful information here!

• Problem with HTTPConnection

  Hello

  I have an app balckberry making an HTTP request and download a JSON object, it works perfectly in all simulators and devices ' "BOLD", Bold2 (5.0), curve, I have two camera a storm 2 (5.0) and a (5.0) 9630 tour where I get the following error message.

  I prefer IOUtilities.streamToBytes (), the approach that you use, which looks like it might have a strong overload.

  It also gives me the ability to decode the octets using UTF-8, that your approach does not.  And it is perhaps part of the problem.  If the server sends UTF-8 and you read it in the way you did, then you could interpret some characters.

• Problems of HttpConnection

  Hi all

  I have an application that is out on the market for a bit it works fine. In the last two days, the httpconnections were incredibly slow and wedging on. no code has changed! Is there something to do with the servers?

  I just added '; deviceside = true' and it worked!... why it worked before with her?

• Http connection problem

  Hello

  I have some problems with httpconnection. I have to make 2 connections, first to retrieve data from a web service. The second is used to play audio data stream.

  Here's what I do:

  First of all, I call a web service using a httpconnection (this works well):

  HttpConnection httpConn = (HttpConnection)Connector.open(sLocator, Connector.READ);InputStream is = oHttpConn.openInputStream();byte[] loadedContent = IOUtilities.streamToBytes(is);ByteArrayInputStream bytestream = new ByteArrayInputStream(loadedContent);
  
  // Some work with the bytestream
  
  is.close();httpConn.close();
  

  Later in the code, I do in a separate thread:

  HttpConnection httpConn =(HttpConnection)Connector.open(sLocator);
  InputStream is = httpConn.openInputStream();
  
  player = Manager.createPlayer(is, "audio/mpeg");                                                           player.realize();
  player.prefetch();
  player.start();
  

  My problem is that this second httpconnection only works if I'm not the first one before (the web service call) (actually only when I comment the web service call the player does his job).

  Am I missing something?

  I'm working on a simulator at the moment (with SDM launched), I didn't add the parameter "deviceside" to my URL.

  However if I join '; deviceside = true' for the second connection, it works sometimes, but only if I use it in the first connection.

  Can you help me?

  Thank you

  Franck

  Hello

  Are you running the connection of two in the same thread? If this isn't the case, I make sure that the first thread of the connection was closed successfully without exception.

  Also, you must add the transport protocols to your all URLS.

  I have the same situation when I make two API calls where the 2nd call API is based on the outcome of the first and I do it in the same thread of connection and it works fine.

  Hello

  I'm setting up a search for blackberry client application.  It made a post when you hit search and retrieves the XML that I use to display information on the search screen. So far so good. This is what my XML looks like:

• Blackberry problems with javax.microedition.HttpConnection

  Hi all

  I am currently working on an application that connects to the Web service using javax.microedition.io.HttpConnection;

  I want to do several generations for the request of 4.7, 5.0 and 6.0. I have a very big problem because as I've debugged since now the request to the server is only to send the version 4.7 and I have not found a solution to work for other versions. The code is the same, but I have an InterruptedIOException with the message that LocalConnection expired after ~ 10000. I had this error on the 9800 Simulator tests.

  How it is possible to work on 4.7 but on other versions of crash?

  Have you had similar problems? Shoud I code to help with this? This is a very critical situation.

  Kind regards

• HttpConnection IOException Tunnel has no problem

  Hello

  I wrote a code that use HTTPConnection to call a url:

  HttpConnection conn = (HttpConnection) Connector.open)

  «http:// *.» ***. : 5556/mobileservice.asmx; deviceside = true; ConnectionTimeout ="+ timeOut, Connector.READ_WRITE, true);

  And I got the IOException:Tunnel Failed on 9000 "BOLD" and the 8900. (So far, I had only to test on both devices).

  I think I had put the apn correctly. So I don't understand the reason for this exception.

  I use post multipart via httpConnection method to upload files on server (website a service net disk, single file size is limited to 500 MB), I tested the Simulator (9800 Asia, software: 6.0.0.706, platform: 3.0.0.159, network: wifi) and download a large file 40 MB, but when I signed my record of cod and tested on the device (9900 (, software: 7.1.0.1098, platform: 5.1.0.701 network: wifi), I had an interruption during about 3 MB of data download and threw a ConncectionClosedException.

  Here is my proposal, when output.write (filled with all bytes) amount (perhaps 10240 bytes), it will download bytes in the buffer to the server immediately, and waiting for filled with bytes remaining and so on. Download the bytes in the buffer may take a long time to wait, if the ConnectionClosedException is took place during this freeze period?

  If I download a file less than 1 MB on the device, it will be probably successful, Yes, not 100% success rates, I do not know what problem I am facing now

  "I don't have limits of authority to deal with pieces of data on the server.

  You might have problems if you do this on mobile service because they can or can not cut you if you try to upload too many bytes, more WiFi, it should work good Chunking is really useful for recovery reboot only, does not provide all of the extra features.

  «the network indicator in the upper right corner of the device screen will flash several times, until the flash stopped writing bytes will continue progress.»

  OK, not my experience with mobile connections, maybe it works that way with WiFi or using the https protocol, which does not establish the connection at first.

  That being said, I don't think I can help a lot here sorry.

• How to manage the HttpConnection to do:

  Hello

  Well, my problem is that I am a httpconnection by blackberry to a tomcat server apache where I have a servlet that establish a connection to a database, I want the blackberry to show me if the connection is successful or not. I have the blackberry to show me the message if was successful or not. This is the code.

  Method that connect to servlet:

  ' public void IniciarSesion (String pLog, String pPass) throws IOException
  {
  String url = "http://localhost: 8081/ConexServ/sv_Conectar";
  OutputStream os = null;
  Try
  {

  HttpConnection hc = (HttpConnection) Connector.open (url);

  hc.setRequestMethod (HttpConnection.POST);

  hc.setRequestProperty ("User-Agent", "' profile/MIDP-2. 0 Configuration/CLDC - 1.0" ");
  hc.setRequestProperty("Content-Language","es-ES");

  OS = hc.openOutputStream ();
  OS. Write (("Log_="_+_pLog).getBytes ());
  OS. Write ((«_&_pass_=_"+_pPass).getBytes ());
  OS. Flush();
              
  HC. Get
  }
  catch (ClassCastException e)
  {
  throw new IllegalArgumentException ("not a HTTP URL");
  Dialog.Inform ("error" + e.getMessage ());
  }
  Finally
  {
  If (OS! = null)
  OS. Close();
  }
  }

  -------------------------------------------------------------------------------------------------------------------------------------

  It's the method that receive the settings in the servlet:

  protected void processRequest (HttpServletRequest request, HttpServletResponse response)
  throws ServletException, IOException, SQLException
  {
  response.setContentType("text/html;charset=UTF-8");
  PrintWriter out = response.getWriter ();
  Journal of the string, pass;
  ConexionBD Conex.
  Try
  {
  GB = Globales.getInstance ();
  Journal = request.getParameter("Log").toString ();
  pass = request.getParameter("Pass").toString ();
  This brand of method the conexion returns true or false

  F. IniciarSesion(log,pass,out);
  }
  Finally
  {
  out. Close();
  }
  }

  Please give on how to do what I want,

  Give the NetworkAPIDemo a glance. This is a very good example on how should be HTTP connections.

  If you are using the eclipse IDE go to file > import > import of samples BlackBerry

  In the new window make sure you click "Clear all" (as I'm sure you don't want to look at ALL the examples right now). Head down to the NetworkAPIDemo to complete the import.

  Samples are a GREAT way to reach 90% of the common tasks that you will implement. It has been my single most important resource.

  You can also see this post: http://supportforums.blackberry.com/t5/Java-Development/Sample-HTTP-Connection-code-and-BIS-B-Access...

  Finally, be sure to use the search feature before asking questions (I know I'm guilty of not doing that from time to time). HttpConnections have been covered ad nauseam.

• Prob HttpConnection BlackBerry running in the Simulator

  I want to call a url and get the response of the url of my Blackberry App data. For this, I use HttpConnection. Here is the code I use:

  dis.readFully (data);
  } else {}
  int ch;
  While ((ch = dis.read ())! = - 1) {}
  //...

  }
  } catch (Exception e) {}
  e.printStackTrace ();
  } {Finally

  try {}

  }

  }

  Public Shared Sub main (String [] args) {}
  _APP = new TestApp();
  _APP.enterEventDispatcher ();

  }
  }

  When I try to run the code in the Simulator, I get ' 0 ', then ' 1' and after that, after much time "no trace of the stack" doesn't appear in the debug window, and as soon as the text makes its appearance, level with the text app becomes visible in the Simulator screen. There is no problem in the internet connection in the Simulator, I set up the Wi - Fi and I tested it I open any Web site in the browser. What is the problem in my code?

  It works very well (showing WaitScreeen, data download), but all characters not English shows as '?'
  I found a few discussions with the same problem (especially this one)

  and this one

  but I don't understand, how and where do I I implemented HttpConnection in my code.
  Please, give me advice or tell, how I change my code to solve this problem?

• Strange connection problem

  This happens on the Simulator and the current device.  I did it on 8800, 8703e, 8320 and 7100i.  OS 4.1 and 4.2.  Also tried on multiple media.  Tried with and without a BES.

  I am able to create an http connection initially, and everything works fine.  I log in, I get my data.  Large.

  However, when I leave my application and go to the Blackberry Desktop and turn the Wi - Fi market then re - enter my app and try to make the same connection, it will not work.

  When you run the debugger, it seems to try and make the ' status int = httpConn.getResponseCode (); »

  line of code and won't go further.  It will be expire.  In fact, he gets caught by the try catch statement.  The Exception toString is ' java.io.InterruptedIOException: Local connection timed out after ~ 120000'

  My connection code is...

       StreamConnection s = null;      String finalUrl = "";       finalUrl = "http://" + login.url + directoryPath + filename + local.getUrlPlus();       try {           s = (StreamConnection) Connector.open(finalUrl);            HttpConnection httpConn = (HttpConnection) s;           httpConn.setRequestMethod(HttpConnection.POST);         httpConn.setRequestProperty("user-agent", "BB DOC");            httpConn.setRequestProperty("content-type", "application/x-www-form-urlencoded");           httpConn.setRequestProperty("connection", "close");         byte d[] = data.getBytes();         httpConn.setRequestProperty("content-length", Integer.toString(d.length));          OutputStream os = s.openOutputStream();         os.write(d);            if (os != null)             os.close();         int status = httpConn.getResponseCode();            if (status == HttpConnection.HTTP_OK) {             InputStream input = s.openInputStream();                //parses the content returned               input.close();          } else {                ;//Had a server connection problem                      }           s.close();          httpConn.close();       } catch (IOException e) {                   ;//Catches the timeout here.        }
  

  Seems the only way to solve this problem is to restart the Simulator.

  Only occurs when the wireless is displayed/hidden market.  Sound like something not be reset or something.  I have simulated this when the unit is made of coverage and brought back in coverage, but the error never occurred.  Only when the wireless is turned on and the.

  What of even weirder, is that I have been using the same connection code for over a year without any problems.

  Someone at - he already experienced this?  Its driving me crazy.

  Any help would be more then appreciated.  Thank you!

  This seems to be a matter of BlackBerry Simulator.  I was able to reproduce and checked that it has been fixed in version 4.3.0 the BlackBerry Simulator.
