• in the waking state socket connection problem

  Hi all.
  My app need update real-time security data, it should be able to run well even the switch of the PB in the waking state.
  The problem is that when PB passes to the waking state and more than an hour later, my application cannot send request for data to the socket server (initially he workd well), even when the PB get again enabled, the socket connection is also unnecessary.
  I did a test as follows:
  1, I added the "throttled" in the blackberry - tablet.xml
  2. I have add a few listiner event in the main class, but each of them can be fired in any time.

  QNXSystem.system.addEventListener(qnx.events.QNXSystemEvent.STANDBY,onDeactive);
  QNXSystem.system.addEventListener(qnx.events.QNXSystemEvent.ACTIVE,onActive);
  QNXSystem.system.requestResource(QNXSystemResource.NETWORKING);
  stage.addEventListener(Event.USER_IDLE,userIdle);
  stage.addEventListener(Event.USER_PRESENT,userPresent);
  stage.addEventListener(Event.ACTIVATE,onStageActive);
  stage.addEventListener(Event.DEACTIVATE,onStageDeactive);
  

  3, I put a clock to save information in / shared folder.it worked well in the waking state.

  Thanks for any response.

  Hello.
  I'm a developer of instant messaging which is connected to the door via socket. What I can tell you for sure I you need to use:
  normal
  That, to use SocketMonitor to ensure that connections are available, some WiFi routers can close idle connection event when U don't want to! If you need to reconnect in such cases.
  Please, feel free to ask for help more.

• I have a problem when you try to receive data using the socket connection.

  Hello

  I created a socket connection between a pc (sever, win32) and a blackberry (client) and I have only two questions:

  -When I send a string to the sever I get the unexpected result, I doubt if it's a problem of encoding between platforms.

  -When I try to receive data, (an array of char as a string object), the customer demand freeze (drawing and management of events, so basically the main UI thread), even if I did all the stuff of connection in a separate thread, until I have shut down the server and also no data is received.

  I left the codes below and would assess any response from you.

  C++, win32 console application:

  SOCKET _Socket;

  int _tmain (int argc, _TCHAR * argv)

  Thanks for your help.

  You treat on the thread of events.

  You have the following code:

  UiApplication.getUiApplication () .invokeLater (new Runnable() {}

  public void run() {}

  try {

  open_connection();

  .....

  Now invokeLater essentially tells the operating system that the associated executable must be run on the event Thread.  You need start a separate Thread.  Extend this Thread, add your code in the run() method, and then start the Thread with start(). (not run()).  Then you must run the networking of processing on a separate Thread.

  This will cause you problems updating the user interface.  Take a look at this help:

  http://supportforums.BlackBerry.com/T5/Java-development/update-a-screen-on-the-main-event-thread/TA-...

  Printing, this means that invokelater a separate Thread is a common misconception.  I recommend you to look at this:

  http://supportforums.BlackBerry.com/T5/Java-development/what-is-the-event-thread/Ta-p/446865

  In addition, I recommend that you take a look at the socketDemo which must be included as a sample-, otherwise you can find it on github:

• Problems with 9000 device establishing a socket connection?

  Edit again: still a problem, see Update 2 to end...

  My app works fine on 4.3 & 4.5, device and Simulator. Also works very well in the 4.6 Simulator. However, on the bold new we just acquired today, I can't do the blackberry establish a socket connection. As far as I can tell a call to Connector.open which has the form:

  String connUrl = "socket://:;deviceside=true";StreamConnection sc = (StreamConnection) Connector.open(connUrl);
  

  .. will never return! I set breakpoints after him in the file and I get nothing. There is no sign of a connection through to the other end. I put a breakpoint on the line with Connector.open so I know is to be worn, but if I click on 'no more' control is never returned to the jde debugger.

  I realize in Application 4.6 permissions have been moved around, but I've set manually the application has permission to connect to the internet. I tried to connect to a server, I know that the blackberry can access (e.g. www.google.com), I expect this to cause then an exception more than my application is obviously not HTTP... but nothing! No indication the Connector.open never call does not return. No exception seems also to be thrown, ControlledAccessException or other... can someone guess what might be happening here? It seems that it is a fundamental thing to do, I don't see what could have changed. My thread Manager program is still running behind all that (I see his messages to regular use of ram) isn't as all users of the application are overwritten or anything.

  My request is signed, I checked several times. I can also access the internet as usual from the blackberry browser. It is also interesting to note that, on the debugger to connect to the device, told me debugging information are missing about two - net_rim_cldc and net_rim_os modules if I remember correctly. Then, he said because of this "many debugging features will not work properly", but as far as I can see, willing or not, debug this connection is simply not be established, and yet no exception or anything is up. The above code is surrounded by try/catch that will catch java.io.IOExceptions and ControlledAccessExceptions, among others, but none of this code is already hit. And surely if it was some type of more exotic exception that I have no intention, I would like to at least get a popup on the screen tell me about an uncaught exception?

  Help would be greatly appreciated!

  UPDATE: standard Version, as soon as I had finished my half hour trying to get this thing to work and then wrote a post about the epic forum, he begins to work. Perfectly as I can tell. I guess it could have been a little temporary bad service from my supplier... Oh well anyway we are all good now...

  UPDATE 2: it appears when wifi connections aren't a problem, but if I turn off wifi problem remains. Any ideas?

  How long did you wait for an exception?  It must expire after 2 minutes if it is unable to connect.  Which way you make the connection?  You use the deviceside parameter?

  The BlackBerry has been activated on a BlackBerry Enterprise Server?  You have completed the information under Options, Advanced Options, TCP APN?  The BlackBerry shows 3G on the home screen (capital G)?

• Maintenance of the Socket connections alive

  Hello developers,

  Please, I have problems to perpetuate a socket connection in my application for a long time. It seems to disconnect after a short (2 minutes) while especially if he's inactive.

  It happens that I have write an application with a Chat feature and for that, that I keep a socket connection Alive for the life - tme of my application. I tried stuff like Ping Server every minute, but then this is a leak of resources (Blackberry). Push BlackBerry is not an option (as I have other clients other than BB devices).

  Please someone know how I can fix this or suggest a different way to go about this?

  I agree with previos answering machine. The problem you have is push RIM invented.  I'm not aware of a way around that. If you cannot use the pusher, then you will have to keep alive and if your app will suffer battery drain and possibly additional costs related to data traffic.

  Some people have used email instead of push as a wau to notify the application that there is something to it: this requires a listener e-mail in the application process and eliminate these notification emails.

  If you do not use a living message of keep, then I think this quesiton becomes useless:

• Socket connection in the Simulator with MDS, but not on the curve

  Hello

  Working on an application using socket connections.

  SOC = (SocketConnectionEnhanced) Connector.open ("socket: / /" + address.ip_number + ":" + address.port_number + ";") deviceside = true");

  Proceed to use a DataInputStream and DataOutputStream to communicate.

  The server works, can transmit very well with the Simulator, but also another curve (not same model). (There is a small chance that deviceside = true has not been passed as a parameter when we tested on the curve, which would go through BES? This is probably still there however).

  IMHO, this means the places that the question could be one) how the code is implemented on the client phone or b) phones or their settings (have 4 curve 8530 s on the same CDMA network).

  -These phones have already activated in the last days, is there the chances that something is missing from the service book to allow socket connections? (I doubt that what I downloaded messenger ping I assume uses taken... and everything is fine).

  No authorization application that I put?

  Ideas! Please let your mind flow. Thank you!

  To all those who might find this thread after encountering the same problem:

  The issue was with the DataInputStream... available() was ALWAYS return zero, even if there are more bytes to read. This is our 8530 s curve 4 tests phones. Tried on another curve and "BOLD" and they did not have this problem.

  Use available() stopped and tried reading for much bigger than one of our packages will be (5000 bytes).

  Have some phones to test with 5.0.0.337 that they would not work with that.

  After the 5.0.0.1000 they all work perfectly.

  I read somewhere that the available() issue has to do with J2SE-> J2ME problems, something on a wrapper. This problem exists (or existed) with TSL/SSL apparently (sorry I can't find the thread I get this info, if someone really wants to see him answer and I'll get the link in the history of my browser of laptops).

  Hope this helps someone!

• socket connection - a reward for $30

  I am building an application that uses the socket connection. When the application runs, my desktop, it works fine, however when it is running on a remote server, I get the security sandbox violation: "cannot load data from serverName.com:portNumber."
  
  There is another application on the Adobe (posted by Josh Tynjala) lab that people have the same problem: http://www.zeuslabs.us/archives/6/connecting-to-aim-with-actionscript-3-sockets/
  
  Josh's response was: "you need to run the SWF to a location on your computer."
  
  Its application works well at the local level, but when I upload it to a remote server, I get: "cannot load data from aimexpress.oscar.aol.com:5190." Is it possible to get the socket connection to work on a remote server and not only on the desktop?
  
  I'll give you $30 (using western union or paypal) if someone can get Josh Tynjala application to work on the remote server.

  The file XML cross was placed in the wrong place, it works fine now.

• AppStore connection problem!

  Hello

  I'm running a 21.5 "iMac with OS X El Captan 10.11.5. My problem is that I am not able to connect to iCloud and the App Store on my Mac.

  The error I get is "there was an error connecting to server Apple ID"

  The same username and password works perfectly well on the site of iCloud, my app store on the iPhone and the iPad, but not on Mac.

  What is the way my iMac communicates via the internet? We have a firewall. And oh, the software update for El Capitan is downloading as I type; He didn't even ask for IDs, just started downloading automatically. The same thing happened yesterday with the updates listed on the tab Update on the app store - they have been is downloaded yesterday without asking my login details but it was a rare event; connection problems I described above took place during the last month or so.

  How can I fix?

  Thank you!!

  Try disconnecting all the services using your Apple ID on your iMac, iTunes, FaceTime, iMessage and try to sing.

• Strange internet connectivity problem

  Hello!

  I'm having a connectivity problem I have never met before. I use a wireless router from Apple with internet cable.

  Yesterday, my computer would be is no longer in contact with my router wi - fi. I get a message that the network could not be attached (I ran the Diagnostics wireless, but it's a whole lot of sense to me empty files). However, I also have a Roku, and which IS connected to the WiFi without problem. I completely stopped and restarted the computer, no joy. Reset the modem and the router, no joy. Still works with Roku, not with the computer. But the weird part is, I have Optimum Online, which allows subscribers to log-in to its hotspots, and it worked! I am connected Optimum wi - fi network on my computer right now.

  So I don't know where is the problem! It is not the router, because this is related work with Roku and is not the computer, because it is connected and working with the Optimum hotspot. What gives?

  Try this!

  Go to the Apple menu > System Preferences > network

  Select a Wi - Fi connection in the sidebar and then click on the button "Advanced...". "in the lower right corner of the screen

  In the list of preferred networks, delete the name of your Wi - Fi network

  Click on the "OK" button to save that change and then 'apply' in the network preferences window.

  Now, go to the Applications folder > utilities > Keychain Access

  Make sure that "Login" keychain is selected and "All items" in the category is selected in the sidebar

  Use the search field to find items that Keychain with the name of your Wi - Fi network and remove

  Quit Keychain Access

  Now try and access your Wi - Fi network

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

  Is there a solution to this problem?

  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.
