Interrupted exception in getting the location?

• Get the location of the device

  I had my application built with HTML5 for OS7, I build for BB10 and I decided to go with a feel more native and waterfalls. I must admit however, the old WebWorks documentation was much wasier and friendly, you had a small example of using each feature.

  I'm having a problem getting the location of the device, I went through the sample application "Diagnoses of the situation", but it's really complicated (he has 3 classes of objects with a ton of features to get the location).

  I'm just trying to find the location of the device, using cell towers, every two minutes. I want to create and the entire class for this? Also, how to trigger this function of the part of Cascades?

  I'd appreciate any help!

      return Application::exec();
      // when loop is exited the Application deletes the scene which deletes all its children (per qt rules for children)
  }
  

  Your file bar - descriptor.xml must contain this line to allow approval of the app for location-based services:

      access_location_services
  

  Also to ensure that location-based Services are enabled under settings on your device.

  Your .pro file should contain this line so that the QtLocationSubset library is linked:

  LIBS += -lQtLocationSubset
  

  I hope this helps!

• Get the location with the name of the city and the country.

  Hi, can someone explain the logic behind this?
  Once we get the coordinate of the location using the gps, how do we use to get the name of the city or the country?

  In addition, what is the difference between 'Place' and "Gps Position" in the authorization?

• get the location of the configuration file for each virtual in a cluster

  Is there way in the cli of power for a list of the location of each file in the configuration of the virtual machines in a cluster?  or even each file configuration on data warehouses?

  Thank you

  For all the virtual machines on the VIServer (s) connected

  Get - VM | Select Name, @{N = "VM Config file"; {E = {$_.extensiondata.config.files.vmpathname}}
  Or if you just want to a single data store
  Get-Datastore | Get - VM | Select Name, @{N = "VM Config file"; {E = {$_.extensiondata.config.files.vmpathname}}
  Replace with the data store you want to run it against, for example to run it against Datastore01

• exception in getting the blob into byte]

  HY guys,.
  I have a problem with my java application.
  I use hibernate to interact with a derby database.
  I've stored an image into the blob field (and not a problem).
  When I try to get the blob into byte array that I have this exception:

  java.sql.SQLException: You cannot invoke other java.sql.Clob/java.sql.Blob methods after calling the free() method or after the Blob/Clob's transaction has been committed or rolled back.

  To get the BLOB I made

  Blob cThumnb = ((Allegato) cAllegati.get(i)).getThumb();
  byte[] cPrev = toByteArray(cThumnb);

  where
  

  private byte[] toByteArray(Blob fromBlob) {
          ByteArrayOutputStream baos = new ByteArrayOutputStream();
          try {
              return toByteArrayImpl(fromBlob, baos);

  Could you help me?
  I define also autocommit to false.
  Thank you
  Concerning

  java.sql.SQLException: you can't call other methods of java.sql.Clob/java.sql.Blob after the free() method is called or after the transaction of the Blob/Clob object has been committed or rolled back.

  So invoke it before calling the free() method or until the transaction has been committed or canceled?

  And why the blob in an array of bytes to all? The idea of blobs is you don't know what size they are and how you treat the content as a stream.

• Where is the calendar Gets the location of the House?

  When I ask the calendar to calculate the travel times it suggests a calculated from the House at the location in the calendar entry. It is said this is home', but when I add something to a close location (5 minutes), he said 14 hours, 25 minutes. I can't understand where he thinks is "Home". I looked in my address book and my entry has a home address that is correct (even if it is a mailbox, but the city is correct)...

  Where he finds the House?

  He probably uses "location services" to determine your current location based on your IP address and Internet routing hops.  Because most computers do not have a real GPS radio (like iPhones), they use location services to best estimate based information available based on your Internet connection.  The problem is that location services based on Internet IPs are easily deceived by how your ISP will route your traffic to the Internet, or things like the use of VPN, TOR, or anonymity.  Depends on the method used for the exact location is.  In your case, it is to be tricked and guess wrong.

  I just found this site that can give you a confirmation of this: http://mylocation.org/

• Get the location of the image within symbol

  I have a symbol with nested symbol.

  The nested symbol moves - and I can get his position like this:

  var mysym = sym.getSymbol("SymbolA").getSymbol ("NestedSymbol");

  Var top = Math.round (mysym.getSymbolElement () .position () .top);

  I also have an image inside a symbol that moves. The above does not work (I guess that getSymbol wouldn't work for an image).

  How can I get the position of a moving image within a symbol - in a manner similar to the foregoing.

  Thank you.

  The image will be set as a background to a div or element of the image

  Now, to read his use of the position

  Var top = Math.round (mysym.$('__').position () .top);

  Yatan,

  In the properties of the receive activity tab, you have an attribute named: jca.file.FileName
  In the value column, you can assign a variable that will contain the name of the directory.

• Where does get the location of the JRE of FF?

  I use Ubuntu Linux 12.04 and 20 of FireFox. The addons tab indicated that my java plugin had security problems and that he was currently blocked. Order of Mozilla was told to change the version of Java, I did. The former was 1.7.0.15 and the new 1.7.0.17 (aka 7u15 and 7u17 respectively). Being a programmer, I use the SDK and have my $JAVA_HOME the value of the JRE in the SDK. Then, I changed symlinks in usr and/usr/lib/firefox/plugins to point to the new version of libnpjp2.so in my updated JRE. Finally, I restarted FireFox... But the addons still show the old plugin!

  So where is Firefox search plugin? Is there a config file that I don't know?

  Thanks for the tip Jscher2000. I checked the full path and pointed out that the plugin is indeed from usr. Then of course, there was a problem with the plugin.

  Based on the links update provided by the Mozilla site, I downloaded the Java JRE lates separately in its own directory. Then, I put the symbolic link in usr to point to this version of the plugin... < path_to_jrelibnpjp2.so

  That fixed it.

  For the benefit of other Linux users: the Java SDK 1.7.0.17 for Linux contains the old version of libnpjp2.so (i.e. 1.7.0.15). God only knows why. Since this is a shared library, it should be OK to simply replace the file with one from the JRE download for version 1.7.0.17.

• How to get the current location in the event thread?

  Hello!

  Can U pls tell me how to get the location where the thread object, it is in method() execution of MenuItem. PLS, tell me-

  I also used the different thread for the getLocation() method. But I do not have the coords of geo location...

  PLS, suggest me-

  My code is as below:

      private MenuItem getGeoCodes=new MenuItem("Current Coords",100,1){
  
                               public void run(){

                                   System.out.println("Latitude :"+coords[0]+" "+"Longitude:"+coords[1]);
                               }
  
                   };
  
      private double[] getLocationCoords(){
          Criteria criteria = new Criteria();
          criteria.setHorizontalAccuracy(500);
          criteria.setVerticalAccuracy(500);
          LocationProvider locationProvider = LocationProvider.getInstance(criteria);
          Location location=null;
          new Thread(){
             public void run(){
                     locationProvider.getLocation(60);
             }
          }
          QualifiedCoordinates qualifiedCoordinates=location.getQualifiedCoordinates();
          double[] coords=new double[]{qualifiedCoordinates.getLatitude(),qualifiedCoordinates.getLongitude()}   ;
           return coords;
      }
  

  But I myself NullPointerException. Coordinates get successfully, if we run the location capability in different function, rather than the event thread.

  Please help me-

  In my opinion, which may be too complicate things a bit. I think he's trying to do is register a LocationListener with his object of LocationProvider. Callback methods, send a message to the UI event thread as follows (no need to spawn threads):

  UiApplication.getUiApplication().invokeLater( new Runnable() {
      public void run()
      {
          // This code will execute on the event thread
      }
  });
  

  EDIT: If your interval is short, you can consider implementing this executable as a class and store an instance in the front.

  When I check the debug information, I found this exception are thrown to the line when he calls Application.getApplication ();

  When I move this code to run in a normal life to screen it works fine. !

  Any help?

  There may be a number of issues here:

  (1) until your Application is actually running, you can't really do any processing.  Your Application does not start running until you

  'enterEventDispatcher() '.

  Hand, all you should do is instantiate your Application.  Manufacturer of your Application should not do anything complicated either, since it works as part of main().

  You can do some activities, for example to add listeners, in main() code that is, in some respects, unfortunate because it lulls people into thinking they can do anything.  ,

  (2) get the location as you do, is a blocking call.  If you need to do it on a background Thread.  You c a get away with that on the Simulator because GPS simulated returns immediately with a location.  So it does not actually block.  But on a real device, code as you can force your application to break.

  (3) you seem to try to do something in the commissioning.  You must be aware, this start-up up is called as part of the start-up of the device and before the unit is fully active.  In fact, I think on a real device that this code will fail because the device is not ready to provide a location in the beginning upward.

  You will find find article, informative and useful for (1) and (3).
