• How to parse JSON data using REST POST format

  I was able to create service for REST and the GET operations.

  Using what I know I can pass variables to the Manager but I would like to know if someone can give an overview by creating REST and POST and process json data.

  Thank you

  You can use the following documents to understand how to create GET and POST REST of service operations. There are examples and step by step instructions.

  (2) this JSON contains the value without a name

  Hey Golzio.

  The problem here is that the primitive JSON Unflatten only makes it easy to parse the JSON data that are well represented by the types in LabVIEW. For cases like this where we have a mixed array types are more difficult.

  It is possible to parse JSON arrays with which coexist types using LabVIEW primitives. This is done by using path of entry to Unflatten of JSON to navigate the JSON data and extract the values you need.

  The following example shows how you can create paths in order to extract the data from your data set:

  

  In this example, you can see how we build the table of path in the loops and Unflatten of JSON to retrieve values one by one. One problem with this approach is that we call the JSON Unflatten several times inside a loop so it could fits well for large datasets with thousands of articles. The advantage is not requiring no external dependencies.

  I am pleased that the JSON toolkit i3 worked for you (I've developed this specific tool kit of full disclosure) and it is good to know that there are other options are available such as the most recent JKI JSON Toolkit and the existing LAVA JSON Toolkit for LabVIEW

  The problem is that DataSource will convert your JSON to a QVariantMap, and not to a QVariantList, as required by the GroupDataModel::insertList ().  Try this:

          DataSource {
              id: dataSource
              source: "myjson.json"
              onDataLoaded: {
                  dataModel.insertList(data.response.myplace)
              }
          }
  

• How to parse RSS feeds using QML (waterfalls)?

  Hallo native devs! I am a beginner in native development and I want to know how to parse RSS feeds using QML cascading?

  I see the example like this:

  Page {
      content: Container {
          background: Color.White
          ListView {
              rootIndexpath: [1]
              dataModel: XmlDataModel { source: "model.xml" }
          }
      }
  }
  

  but, can I to ' source: ' use 'http://example.com/rss.xml'?

  If Yes, how can I analyze?

  Thanks for the help!

  The QML in your message assumes that the XML file is local, if you use a remote XML file then you will need to firstly using a few backend Qt C++ network code, download, then you can use QML.

  I would recommend from the Cascades sample quotes to get an idea of how XmlDataModel analysis work can start to look into the network access code and the file.

• How to parse the XML from the server BB10 Cascades development

  Hi all

  I'm new to BB10 development.

  I made the connection with my server that sends data to the XML Format. How to analyze.  Can someone help me with this.

  Also how to store data analysed in the Global Variable or ArrayList.

  Concerning

  Stephenson

  I thought you wanted to do stunts (qml).
  I use Qt

  QByteArray data = currentReply->readAll();
  xml.addData(data); //xml is a QXmlStreamReader
  

  to parse the xml, it is pretty simple if you look at the API.

  Here is a snippet of my code:

  while (!xml.atEnd()) {
      xml.readNext();
      /** start of an element **/
      if (xml.isStartElement()) {
          currentTag = xml.name().toString();
          if (xml.name() == "version") {
  

  the feed reader goes hierarchically, so you can simply call routines to analyze the different parts of the xml if the name() corresponds to a certain value.

• Ugh... Requirement: A TimerTask making an HTTP call, parsing JSON, insertion into a SQLite database.

  How to implement a better design of the following?

  I have a UiApplication which has the following requirements:

  1. A static timer in the class that extends UiApplication.
  2. A class that extends screen and contains a class internal which extends TimerTask.
  3. When a user accesses to the screen, the TimerTask is started with:

     _timer.schedule(MyTimerTask, 1000, 15000);
     

  4. The first step is to do an HTTP call and return a valid JSON object which varies in structure - that is, it has a wide variety of paintings and JSON objects.
  5. The second step is to analyze and insert the JSON object values into tables in a SQLite database. The SQLite file is on the map.
  6. The third step is to read the updated SQLite table, loop through the table and build my ObjectListFields with the new values, and attach them to a VerticalFieldManager.
  7. The fourth step is to replace the old VerticalFieldManager with the new VerticalFieldManager and push the screen pop and updated then the current screen - so I have a stack of view high one single layer.

  Now the logic is actually on the spot, but since the TimerTask must cover every 15 seconds, I am a memory leak in all directions.

  To try to solve this problem, I have:

  • Cancelled the TimerTask with the onObscured and the onUiEngineAttached (false).
  • Restart the TimerTask with onExposed and onUiEngineAttached (true).
  • My DatabaseConnection closed the finally statement.

  However, when I look at the objects in Eclipse BlackBerry objects View when the TimerTask is not running, I still see 1 ~ 4 TimerTask objects and 1 ~ 4 DatabaseConnection objects.

  TimerTask both DatabaseConnection have a static instance (I don't have several entry points) with the following in my class that extends UiApplication:

  public static Timer _timer = new Timer();
  public static Database db = null;
  

  I attribute db when I need it with a call to DatabaseFactory.open within the class that extends TimerTask.

  Now that the business logic is correct, how to improve the design so I don't not leaking memory in every way?

  The statement closed the database is being called in, because I can set a breakpoint and see it has reached.

  Instead of onObscured/etc, you can move them into onVisibilityChange (boolean) is only in one place. Cancel your existing TimerTask before running a new, or at least check the TimerTask reference if you are only creating a... not just passing 'New TimerTask' in the calendar method without being able to track this object reference.

• How to use JSON?

  Hello

  I am writing my first blackberry application.

  I can receive and analyze the JSON files without any problems, but it is not very tidy.

  Basically, app will have 3 screens. First 2 screens will receive JSON files and analyze, last screen will collect the form entries and send back to the server.

  Advice on how should I apply it?

  discussions are started using start(), do not run (all made that mistake at one time or another).

  I would also say to start the thread of the application constrcutor, not on screen one, just to keep things a little separate. While BB violates MVC on some parts, you should try to stick to it.

  You can find many examples on the recall, for example

  http://www.JavaWorld.com/JavaWorld/javatips/JW-javatip10.html

  After you have assigned your json object, you can use the callback method to publish it. See the link above, you can add it as an argument to the interface method.

  Now let your screen implement this interface. and give your thread of an instance of the form as a parameter (wrapped in the interface).

         ConnectionFactory connFactory = null;
          ConnectionDescriptor connDescriptor = null;
          HttpConnection httpConn = null;
          OutputStream stream = null;
          InputStream inputStream = null;
  
          String foo = "{\"first\":\"joe\",\"last\":\"smith\"}";
  
          try {
              connFactory = new ConnectionFactory();
              connDescriptor = connFactory.getConnection(url);
              if (connDescriptor != null) {
                  httpConn = (HttpConnection)connDescriptor.getConnection();
                  httpConn.setRequestMethod(HttpConnection.POST);
                  httpConn.setRequestProperty("Content-Type","application/json;charset=UTF-8");
                  httpConn.setRequestProperty("Content-Language", "en-US");
  
                  byte[] postdata = foo.getBytes("UTF-8");
                  httpConn.setRequestProperty("Content-Length", Integer.toString(postdata.length));
  
                  stream = httpConn.openOutputStream();
                  stream.write(postdata);
  
                  int responseCode = httpConn.getResponseCode();
  
                  StringBuffer sb = new StringBuffer();
                  inputStream = httpConn.openInputStream();
                  InputStreamReader isReader = new InputStreamReader(inputStream);
                  char i;
                  int j = 0;
                  while( (j = isReader.read()) != -1) {
                      i = (char)j;
                      sb.append(i);
                  }
  
                  inputStream.close();
              }
  
          } catch (Exception e) {
              System.out.println(e.getMessage());
          }
  

  Server-side code:

  String query = null;
  String json = null;
  
  json = Request.Form["add"];
  JavaScriptSerializer js = new JavaScriptSerializer();
  MyObject o =  js.Deserialize(json);
  

  Validation of my Android application is successful.  What Miss me?

  If you look at my post

  Looks like you need to use URLEncodedPostData as you use variable form, in your case 'Add' on the side server. In my code, it's "Data".

  However as you can tell to my post I am having issues when trying to post more than 1 K with some example 8900 devices. I am currently an investigation to see if this is because I am using form variables
