Http connection problem

• HTTP connection problem. What is going on?

  I am trying to write a simple program to test the validity of the URL via a http connection.

  For the good URL, the program works very well.

  Bad URL however found two ways:

  1: no answer at all (program runs as if nothing happened, waiting for user input.) The text in the EditField is the same incorrect url intentionally being tested)

  2: IllegalArgumentException in RIMConnector.open (int, int, String, boolean, FirewallContext) line: 76.

  What is going on?

  Here is the code:

  import java.io.IOException;
  import javax.microedition.io.Connector;
  import javax.microedition.io.HttpConnection;
  import net.rim.device.api.ui.*;
  import net.rim.device.api.ui.component.*;
  import net.rim.device.api.ui.container.*;
  import net.rim.device.api.ui.UiApplication;
  
  final class UrlCheck extends UiApplication {
      private EditField urlField;
      public static void main(String[] args) {
          UrlCheck theApp = new UrlCheck();
          theApp.enterEventDispatcher();
      }
  
      public UrlCheck() {
          MainScreen theScreen = new MainScreen();
          LabelField title = new LabelField("URL Check");
          theScreen.setTitle(title);
  
          urlField = new EditField("URL: ", "", Integer.MAX_VALUE, BasicEditField.FILTER_DEFAULT);
          theScreen.add(urlField);
  
          FieldChangeListener listenerCancel = new FieldChangeListener() {
              public void fieldChanged(Field field, int context) {
                  String URL = urlField.getText();
                  HttpConnection conn = null;
                  int response = 0;
                  try {
                      conn = (HttpConnection)Connector.open(URL);
                      conn.setRequestMethod(HttpConnection.GET);
                      response = conn.getResponseCode();
                      if (response == 200){
                          Dialog.inform("URL OK");
                          return;
                      }
                      if(response == 401){
                          Dialog.inform("URL Requires Authorization");
                      }
                  } catch (IOException e) {
                      e.printStackTrace();
                      Dialog.inform("Bad URL");
                  }
              }
          };
          ButtonField checkUrl = new ButtonField("Check");
          checkUrl.setChangeListener(listenerCancel);
          theScreen.add(checkUrl);
          pushScreen(theScreen);
      }
  }
  

  Okay, that was stupid.

  I caught the IllegalArgumentException as well and it fixed the problem.

• Get Cookies from a HTTP connection problem?

  Hi all!

  I'm trying to get the Http cookie header. This is my code to display the header

  for (int j = 0; j)< 20;="" j++)="">
  Key of type string = httpConn.getHeaderFieldKey (j);
  String field = httpConn.getHeaderField (j);
  If (key == null & j > 0) {}

• Problem in the http connection. (simulators 5.0 os blackberry 9000 smartphone)

  Hello friends,

  but when I try 4.7 and 5.0 for Simulator that I download this Simulator my project does not work correctly the problem of http connection. Someone tell where I'm wrong?

• Problem Timeout of the weird HTTP connection on the BES!

  Nice day

  I seem to be lost on a TCP connection problem.

  Basically, I opened 'a' connection via TCP, and after a period of 120 seconds of inactivity, it is cleaned by the BES. Now, I've read a resource that provides information about a parameter, the "ConnectionTimeout", which I've tried setting 5 minutes (300000 ms). But this does not solve the problem. In addition, I changed a parameter in the MDS, the 'HTTP device connection period' to 300000 (ms) as well. And Ditto for the rimpublic.property file, which is located in the directory config of the BES.

  Everything seems to indicate that the maximum connection time is 120 seconds. Is this correct? This value can be overridden? If this isn't the case, so why give the possibility to increase the time-out period, without going through a sort of validation?

  Advice will be useful, the way I bypassed, now, to renew or create instance login every 90 seconds.

  See you soon,.
  Nik.

  The parameter side pocket allows to reduce the timeout to a value less than the default value set for the BlackBerry Enterprise Server.  May not go beyond what is on the side server.

• HTTP connectivity from a device problem

  Hello

  I'm working on an application that works with our web server via HTTP and HTTPS.

  As it is a consumer application, we want to operate without MDS, out-of-the-box when a smartphone is purchased at retail with a web access data plan.

  I assumed that this means using direct TCP when a Wi - Fi connection is not available.

  The following code snippet prepares the URL according to the configuration, and opens the connection:

  String fullUrl = (isSecure? ("https://": "http://") + appConfig.getServerHost () + "/" + url + (bbAppState.isWiFiOnly ()? « ; (interface = wifi': "") + (bbAppState.isDeviceSide ()? « ; (deviceside = true': ' ");

  c = (HttpConnection) Connector.open (fullUrl, Connector.READ_WRITE, true);

  Details of equipment and network:

  Feature: 8320
  OS 4.5.0.81
  T-Mobile US network
  Have a data plan (unlimited web and 400 messages)
  Connection preference: Wi - Fi preferred
  No apn is not specified
  Browser and third-party applications downloaded from the App World can access internet via Wi - Fi and EDGE/GPRS with the above parameters
  

  Tried:

  1. Free Wi - Fi and EDGE: deviceside = true - get "Tunnel failed '.
  2. Free Wi - Fi and EDGE: no deviceside, only the url - get "Tunnel failed '.
  3. No deviceside, only = wifi interface - works with a Wi-Fi connection, reports "The Tunnel failed" when out of range of a Wi - Fi connection.
  4. I tried parameter APN to internet2.voicestream.com just to test - got the same error 'Tunnel failed '.  I would not use it as the browser and other applications need and work when the APN is empty.

  My question is if I'm something wrong or missing something.  My hypothesis is that third-party apps and BlackBerry Internet Service browser.  Is there a way to know?  Is there a way to disable it (for example to make sure that the browser and other applications use it)? Our company has recently become a partner of Alliance of BlackBerry, so we can apply to BlackBerry Internet Service, but I do not understand if this is necessary for consumer applications, or if the consumer applications should rely on direct TCP.

  Any help will be greatly appreciated.

  Thank you

  Sergey

  Use '; deviceside = true ', you must also specify the details of the AFN, the options of the device or in the string you provide with "; deviceside = true '.  If you do not, you will get "Tunnel failed '.

  I would like to confirm the settings for T-Mobile APN - the value that you used does not match what I found in a google search.

  Browser and other applications will use WAP 2.0 or BIS - B, requiring no configuration.  You can use WAP 2.0 - standard article for more details:

  Recommendation - use BIS-B (service Alliance Partner) If you can, work in cases more than anything else.

• Problems with HTTP connections in 7.0

  Hi all

  HTTP connections in my work of fine application with 5.0 and 6.0, but they do not work with 7.0.  Enough actually, they work with 7.0 when the device is connected with WiFi, but not with 3G (Sprint) mobile network.  Connections are also running smoothly on the Simulator.  When the application tries to perform an HTTP request, it seems to open the connection, but the connection hangs just until it expires in a minute later.

  I'm unable to debug applications with the SDK 6.0 and 7.0 in Eclipse.  The debug mode is always suspended my environment.

  Can someone speculate as to why this might be the case?  For added convenience, my code is below:

  public class HttpRequest extends Thread {
      private String method; // GET or POST
      private RequestResults screen;
      private String url;

              }
          }
  
          return null;
      }
  }
  

  The culprit seems to be adding the line

  ConnectionUID = record.getUid ();

  for my URL when you set the connection settings:

  if (record != null && (coverageStatus & CoverageInfo.COVERAGE_DIRECT) == CoverageInfo.COVERAGE_DIRECT) {
  // Have network coverage and a WAP 2.0 service book record
      connectionParameters = ";ConnectionTimeout=10000;deviceside=true;ConnectionUID="
      + record.getUid();
  }
  

  Once I have remove this, it works fine...

  As I said, if you use the Sun plug-in, you MUST add the name of the jar file to the tag archive .

• connection problems with the version 6.18.0.106

  Hello

  I have Windows XP and I have always used an earlier version of Skype, but now the old version is retired and I can't use it. So I download the new version 6.18.0.106, but this one has a connection problems. Every 4 seconds, I am offline and then online again for 4 seconds. My connection is OK and my provider does not block Skype calls. Is there anyone who knows how to fix?

  Try to uninstall the latest version and install the older version of Skype 6.14.0.104:

• Connection problems: Win7, Skype 6.14

  Hello

  I had connection problems since just after I did a windows update last night. (no idea if it's just a coincidence?)

  I read through several other posts here, tried reinstalling Skype several times (also re-installed an older version), checked the compatibility mode and still no joy. Oh, I restarted a few times too.

  I'm trying to connect using my Skype username and password (I don't have an account of ms) but the screen is just stuck there, it says signing in and the whirly thing (term techy lol) is just Dervishes round and round.

  I luuuurv my Skype, absolutely essential for me because I work from home, so I hope someone can help. PLEEEEASE :-)

• LJ pro M177fw: eprint center connection problem

  Hello

  today I am trying to add my new printer to my eprint account, but I do not remember my pwd, so I want to co reset the password.

  By e-mail, I received a link

  http://h30495.www3.HP.com/reset_password/xxxxxxxxxxxxxxx

  but it didn't work, the Web server show this error:

  SERVER ERROR

  Oops! Only, something was wrong with our server.

  Try refreshing the page.

  I tried different browser and pc, but I can not reset my pwd.

  Is there a solution to this problem?

  Is the server down for ever?

  Thank you and best regards.

  Hey @Roberto_ITALY,

  Thanks for posting in the Forum from HP Support.

  I understand that you are unable to claim your HP Color LaserJet Pro MFP M177fw in your account ePrint Center due to a connection problem.  I would like to help.

  I don't see this particular error with password resets from time to time.  I have a workaround that can clear up this place for you:

  • Click here.  This will bring you to <www.snapfish.com >.  As the Snapfish site is linked directly with ePrint Center and HP connected, you can try to reset your password as follows - click the connection icon and then "forgot your password":

  

  • Enter the e-mail address that you use to connect to the ePrint Center and click on submit.
  • You should receive a message of automatic reset of password by email - the reset as expected before and then try to use this new password to Snapfish to connect downtown ePrint.
  • If this does not solve your problem of access ePrint Center, please call our Cloud Services to 855-785-2777. If you do not live in the United States / Canada region, please click the link below to get help from your region number.
    
    http://WWW8.HP.com/us/en/contact-HP/WW-phone-assist.html

  I hope this helps.  If my suggestion worked in your favor, feel free to give me a virtual h.o.t. by clicking on the 'Thumbs Up' icon below.
