  Hello ,.

  Why Connector.Open displays an error as seen on the attached picture?

  Thank you

  If you place the mouse over the error indicator, you should see more information.

  In this case, I think that your imports you don't

  Import javax.microedition.io.Connector;

  Instead, I suspect that you have another class of connector.

• ("VMError when calling code Connector.open("file:///c: ") (and a few other formats)

  Hello all, thanks for reading this question. I'll start with the problem. I wouldn't actually call the Connector.open with "file:///c:" as an argument for the real program. I've just simplified to do later when it did not work to try to find the problem.

  Data sheet:

  JDE4.5

  Using components package 4.5 Eclipse plug-in

  Running in from Release or Debug in the Blackberry Simulator

  Code:

  ("To debug in my code it rolls up to what I touched the Connector.open("file:///c line: ") I also tried these formats.

  Connector.Open("file:///c:/"); "

  Connector.Open("file:\\\c:\\") "

  ("Connector.Open("file:\\\c: ")

  originally it was-

  Connector.Open("file:///c:/Caleb/middieFolder/") "

  I tried the same thing above formatting with this URL

  The problem:

  When I hit this line of code with one of the strings above as an argument it throws this exception

  Exception class - FileIOException

  Message:-e.getMessage () actually get an error also. net.rim.VMError - I get a message at the bottom of my Ctrl + Maj + I window - net.rim.vm.VMError calling toString.

  (This probably happens because it is null)

  _errorCode = 1003

  backtrace = null

  I guess for some reason any he just dislikes the URL I provided what is a good way to test this? can I call to C: if I'm testing this on my computer?

  Thanks for any help.

  ' c: / ' does not exist. You call the same path in the Simulator as you would on the device. Set the Simulator to simulate a SD card is inserted.

  Hello

  I tried everything and still does not work. It took me days to realize that the problem was not on the stream. I update a label of a different thread, which causes blocking. Problem solved.

  Thanks anyway.

• connection problem, using Connector.open ()?

  While m, try the following code:

  HttpConnection conn = (HttpConnection) Connector.open ("http://www.nasa.gov/rss/hurricaneupdate.rss");

  my phone is stuck on this line:

  conn.openInputStream ();

  and after a long time he gives IllegalStateException, can anyone suggest the reason or another?

  And looking at the basics of network processing, maybe you should check the thread of events.

  "the problem is that hconn.openInputStream () is not yet back stream, it stucks on this line and alter long Simulator says"IllegalStateException.

  This is caused by your Exception handling is attempting to add a LabelField on-screen - but your exception handling runs in your net shot.  So you get IllegalStateException because you must run on the event Thread or blocking of the event to do this.

  Search for resources to explain the event Thread - there is a little.

• SecurityException when calling Connector.open)

  I develop a client application that uses the REST API of the application of corresponding server, which is built by our company.

  We are targeting devices with software system 4.5 and upward, but we can give up to 4.5 in the near future and 4.6 making the new lower limit. Currently, dropping support for anything below 5.0 altogether is not an opption for us as we are invited to support devices that are actually used.

  Therefore, I am building with the SDK version 4.5.0.28, but I also tried with 4.6.0.23 and got the same results.

  The current REST API of our application server using GET, POST, and DELETE requests, so I had to use SocketConnection and build my own HTTP management code to implement the DELETE method.

  There are different instances of the application server (tests, staging, production) with different names, but in the case of normal use from the end user perspective the app would stick with a host. That's why I designed the code that handles the application permissions associated with access to the network, to ask permission to access the host currently configured (-> getPermission (authorization, domainname)).

  Until now, I used mostly a host for testing. I went once the host when I had to use a host with a new version of the application server. Despite the carrier/network related issues I never had a problem to access hosts.

  But now, while testing the new code I suddenly unexpected trouble.

  At one point, I changed the hostname to use a different server host and since then, I get a SecurityException exception as soon as Connector.open () for a https URL is called. I get it even after changing to the previous host name. The chain of reason is simply "Permission denied."

  I checked that day:

  • This isn't a ControlledAccessException. I checked them both, but only SecurityException caught.
  • The ApplicationPermission API returns true when I check the permissions. The permissions are checked at startup and permissions request dialog box is shown if they are not appropriate. They are also checked before trying to access the network via a specific transport.
  • The firewall seems not to be bound: this Exception is raised, that the firewall is disabled.
  • I'm testing with a Bold 9000 and the software version 4.6 and a Torch 9800 with version 6.0 of the software. The bold is connected to a BES and COMPUTING strategies do not allow me to disable the firewall. The torch is "autonomous" and the firewall is disabled by default.
  • I tried it with a torch Simulator and found that it will work when I disable 'security '. The Exception is also thrown in the simulator when turn on (and running the signed application).
  • I compared the files *.csl of previous generations with the current generation and not found any missing entries.
  • I changed my code to request permissions to access the network without limiting it to a specific domain.
  • I deleted the app on devices and installed again - and still get the same result.

  I find it rather suspicious, I don't get the usual "application to establish an https connection" dialogue when I use the https URL.

  I actually get the similar dialog box when I change the code to use the SocketConnection to GET using a ssl URL. Access to the network works even in this case, but my implementation of HTTP is still too rudimentary to be useful in this case.

  So my question is: what can trigger this SecurityException? Which component actually don't "deny permission?

  And can be linked: is permission to access a specific server via http/https or ssl/socket stored somewhere on the device so that it will survive even the corresponding application uninstalling?

  I'm looking in the wrong way and there is something else going on here?

  I'd appreciate any help to get this case closed.

  Thanks in advance,

  webbasan.

  I mainly use the Desktop Manager to deploy the application during the tests. But some of my "Beta-testers" get via OTA.

  But I found the true cause yesterday: due to some changes in another place, I got the schema uppercase names when creating the connection URL.

  Unfortunately, this "SecurityException: Permission denied" message points to the real problem, that's why I was looking in the wrong places.

  Why not throw an IllegalArgumentException instead? Accepting names uppercase regime would be another option, because this is the behavior recommended by the corresponding RFC. (Ok, the RFC also States that a client must use the lowercase schema names, so this would again direct the question to me. But then again - a correct description of the true cause would help a lot...)

  After all I found in this bug-hunting that HttpConnection actually doesn't accept 'REMOVE' even with the SDKs for 4.5 and 4.6. At least enough that it works for my use case. So my own SocketConnection based HTTP application is not really necessary after all...

  Thanks for giving some comments after all!

  webbasan.

• (FileConnection) Connector.Open ("file:///" + path)

  So I'm doing something like this:

  case FileSystemJournalEntry.FILE_ADDED:

  Path String = entry.getPath ();

  Then I do a: (FileConnection) Connector.open ("file:///" + path)

  What's weird, is that the path which sees the code is as follows: file:///SDCard/BlackBerry/pictures/whatever.jpg

  (he throws a net.rim.device.api.io.file.fileIOException: file system error)

  If I bring up the image and look at its properties, it is said: Card/BlackBerry/pictures/whatever.jpg/Media

  I guess the problem is:

  (a) I have too many slashes in my address of file

  (b) there are certain aspects of black magic for why card/Media / and /SDCard/ seem to disagree with them?

  Thank you very much!

  There must be exactly 3 slashes...  2 for the Protocol: file system "file://" and 1 that indicates the high level of the page: "/ SDCard".  'Media Card' is just a nice alias that you see when you use the built-in apps.

  "file:///SDCard/something...". ' must be correct.

• Problems with Connector.open

  I'm having a problem with the re-login to a HttpsConnection once a failure has occurred. I send a message to a php site that works 100% OK. However, if I drop the receipt when sending at the reception is retrieved Connector.open no reconnect not (even after a long wait). and gives a "java.io.InterruptedIOException: connection Local has expired" exception. The issue is not corrected until the phone is rebooted.

  I use MDS to transport and endpoint certificate has a valid certificate (does not Self-signed). Before I drop the front desk, a message is sent correctly and using the console creates the following log entries:

  [0,0] * start sending:

  [0,0] SSL :-> CH

  [0,0] SSL:<>

  [0,0] SSL:<>

  [0,0] SSL:<>

  Once the reception has been abandoned and valued, the connection begins to open the SSL session and shows the following:

  [0,0] * start sending:

  [0,0] SSL :-> CH

  He gets Nevers to: SSL [0,0]:<>

  After the time-out period, it then returns the exception

  IO exception: java.io.InterruptedIOException: Local connection timed out after ~ 15000

  [0,0] * Flushing bos

  [0,0] * emptied all

  Try to use the factory connections if you are targettin devices in 5.0 or above, it might solve the prob.

• FileConnection Connector.open throws the exception on Blackberry 7 when there is no file

  I'm trying to run a program I developed on Blackberry 6 on the torch 9801 running Blackberry 7.  When I try to open a folder that doesn't exist isn't using FileConnection Connector.open Blackberry 7 to launch a 1003 error. Under 6 Backberry, no exception is thrown, and I could use the FileConnection.exists () function to determine if the file exists. The directory, I'm trying to reference/store/home/user/IUIDChecker/my code below:

  private void createresultdirectory(String result_path) {
          try
          {    // the final slash in the folder path is required
               FileConnection fc = (FileConnection)Connector.open("file:///" + result_path, Connector.READ_WRITE);
               // If no exception is thrown, the URI is valid but the folder may not exist.
               if (!fc.exists())
               {
                   fc.mkdir();  // create the file if it doesn't exist

• Help! its very urgent... I faced connector.open () [new]

  Hello guys,.

  This my first post, I hope that you guys will solve my problem. I'm creating a client-server application where data exchange on Wifi. Everything works very well. But as I open and close the single connection (as my application requires it), after having worked continuously for long hours the IOException occur.

  con = Connector.open (url, Connector.READ_WRITE); Error

  Connection con = (StreamConnectionNotifier);
  SC = connection.acceptAndOpen ((StreamConnection));

  I opened this topic in a thread not differ in hand.

  Please help me...

  The first thing to note is that this treatment will be on a separate Thread.  It seems that this code is in the class that you have which extends UiApplication, so may not be the case.

  The second thing is that you should not close the stream using an invokeLater.  This thread must be running in the background and so you should be able to simply close the stream.

  Finally you will not get a stack trace in an Exceptin like that.  So, you can remove the e.printstacktrace ().

  This is now a pseudo-code to describe how I would implement, this:

  Boolean done = false;

  While (! done) {}

  try {}

  }

  Close all streams

  Thread.Sleep (5000);

  rest the connection for 5 seconds so that it can overcome the problem.

  I hope this helps.

• Request to connect Bluetooth L2CAP to Connector.open (...)

  I am relatively new to Java and Blackberry development in particular.

  A L2CAP connection request is authorized. I pass on the following URL:

  URL = "btl2cap: / / ' + rmdv.getBluetoothAddress () +": "1007;

  to Connector.open (real url, Connector.READ_WRITE),

  I finally get a good return.

  Somewhere along the way, I also have a popup asking for a PIN for pairing. My understanding is that the matching is a top-level as the L2CAP layer function, so why would opening an L2CAP connection cause the popup PIN.

  We create both sides of the connection and do not use a stack of existing server.

  Any suggestions on how to do this would be greatly appreciated. More importantly, is it still possible?

  Sincerely,

  Anil S.

  The BlackBerry supports the L2CAP connections when using JSR 82 on BlackBerry BlackBerry handheld software version 4.2.1 running and superior.

• SMS port already in use... MessageConnection using connector.open

  I created an application that listens for incoming txt messages and it works very well on all devices except the 8330... works of ideal app on all phones on sms listening but on the 8330 I get the problem where the exception says "port already in use"... my application is currently in beta and a user reported he was continues smart guard... as soon as he took the chip guard the app works perfectly... so im guessing as smart guard uses sms messages to intitate itself is what is the origin of the port problem... is there anyway around this? my code is below...

  public void open()
      {
          this.controller.write("Attempting to open message connection (Message tracker)");
          try {
              this.msgconnection=(MessageConnection)Connector.open("sms://:0");
          } catch (IOException e) {
              this.controller.writeToConsole("Error opening message Connection (MessageTracker) "+e.getMessage());
          }
          try {
              if(this.msgconnection!=null)
              {
              this.msgconnection.setMessageListener(this);
              }
          } catch (Exception e) {
              this.controller.writeToConsole("Error adding messagelistner (MessageTracker) "+e.getMessage());
          }
      }
  

  MessageConnection is pretty useless, since only one application can attach to the SMS port at a time.

  My advice is to switch to use the method of datagram.

• IllegalStateException on Connector.open

  I have an application with two entry points - he follows the pattern described in DB-004066 how allow - a listener in the background detecting and update a GUI application.  The part of the application that runs in the background from time to time uses the http protocol to get data.  All of a sudden, however, I'm getting IllegalStateException - 'no instance of application', when I try to create the connection using something like this:

  HttpConnection httpConnector = (HttpConnection) Connector.open(theUrl);
  

  I can't understand why this is happening just on this spot. The Connection.open method document that it sews thrown exception, and documentation for IllegalStateException said only that she is thrown when a method was called"once illegal or inappropriate". But I can't understand why in the world my request would be in an illegal state. Most of the information I found actually points to this exception thrown due to a sort of interaction of the user interface outside the event thread - but I'm not stage any type of UI interaction here at all. Anyone have any ideas? It drives me crazy.

  Thank you

  Joe

  MyApp also extends UiApplication?  If this is not the case, the system cannot be able to display the prompt firewall required to allow the connection.  In this situation the IllegalStateException would cause the device attempts to display a GUI (the firewall prompt) for the application when it is not in condition to do so.  I recommend having a look at the link and the example below.

  Why cannot open iTunes with windows 10

  For general advice, see troubleshooting problems with iTunes for Windows updates.

  The steps described in the second case are a guide to remove everything related to iTunes and then rebuild what is often a good starting point, unless the symptoms indicate a more specific approach. (Yes, I see that you've done that but maybe not the specific deletions which are mentioned).

  Review the other boxes and other support documents list to the bottom of the page, in case one of them applies.

  More information area has direct links with the current and recent buildings if you have problems to download, must revert to an older version or want to try the version of iTunes for Windows (64-bit-for old video cards) as a workaround for problems with installation or operation, or compatibility with QuickTime software or a third party.

  See also install missing components in case the installation of a component at a time is successful.
