• JavaScript never invoked in jsff

  Hello
  
  the use case is jsff, in the column of the table row when the user presses the ENTER key, I need to call some methods subsequently (jdev 11.1.2.3)

• AssertIdentity() custom identity Asserter never invoked method

  I'm trying to implement a custom identity asserter. I created my Asserter custom identity following the documentation (http://download.oracle.com/docs/cd/E12839_01/web.1111/e13718/ia.htm#i1156163) and an example on Weblogic wonders (http://weblogic-wonders.com/weblogic/2010/03/15/custom-identity-asserter-for-weblogic-server/).
  
  The problem is that the assertIdentity() method is not called.
  
  I used a simple web application to test the asserter. Its web.xml is like this:
  < security constraint >
  < web-resource-collection >
  Pages protected < Web-resource-name > < / web-resource-name >
  < url-pattern >/app / * < / url-pattern >
  < / web-resource-collection >
  <!-this-> a defined security role References
  <>auth-constraint
  MYROLE < role name > < / role name > <!-MYROLE is also defined in weblogic.xml as part of security-role-assignment->
  < / auth-constraint >
  < user-data-constraint >
  > transport security < NONE < / transport-guarantee >
  < / user-data-constraint >
  < / security constraint >
  
  <! - authentication method - >
  <>login-config
  FORM < auth-method > < / auth-method >
  < form-login-config >
  login.jsp < form-login-page > < / form-login-page >
  rejected.jsp < form-error-page > < / form-error-page >
  < / form-login-config >
  < / login-config >
  
  These are the elements of MDF of my identity Asserter:
  < MBeanType
  Name = "MyAsserter".
  DisplayName = "MyAsserter."
  Package = "com.pccw.security.policysvr.agent.weblogic."
  Will = "weblogic.management.security.authentication.IdentityAsserter."
  PersistPolicy = "OnUpdate".
  / >
  < MBeanAttribute
  Name = "ProviderClassName".
  Type = "java.lang.String".
  Writeable = "false".
  By default = "& quot; test. MyIdentityAsserter & quot; »
  / >
  < MBeanAttribute
  Name = "Description".
  Type = "java.lang.String".
  Writeable = "false".
  By default = "& quot; My identity Asserter & quot; »
  / >
  < MBeanAttribute
  Name = "Version".
  Type = "java.lang.String".
  Writeable = "false".
  By default = "& quot; 1.0 & quot; »
  / >
  < MBeanAttribute
  Name = "Base64DecodingRequired".
  Type = 'boolean '.
  Writeable = "false".
  Default = "false".
  / >
  < MBeanAttribute
  Name = "SupportedTypes.
  Type = "java.lang.String [].
  Writeable = "false".
  Default = "new String() {& quot; MyToken & quot ;} »
  / >
  < MBeanAttribute
  Name = "ActiveTypes".
  Type = "java.lang.String [].
  Default = "new String() {& quot; MyToken & quot ;} »
  / >
  
  At this point the MyIdentityAsserter checks simply token type is correct, then return a CallbackHandler custom that contains a hard-coded user name.
  
  Here is the custom CallbackHandler:
  
  / public class MyAssertionCallbackHandler implements CallbackHandler {}
  
  private String userName;
  
  public MyAssertionCallbackHandler (String userName) {}
  Me.username = username;
  }
  
  @Override
  public void handle ([recall] recalls) survey IOException,
  {UnsupportedCallbackException}
  for (c reminder: reminders) {}
  If (ch. instanceof NameCallback) {}
  NameCallback nc = c (NameCallback);
  nc.setName (userName);
  }
  }
  }
  }
  
  In the web console, I configured MyIdentityAsserter as the first element. When you start the server, I saw its initialize method is called. However, when I hit a page protected in my test application, he went directly on the login form.
  
  At first I thought that there is a problem with passing the token, so I used "Modify Headers" add-on for FireFox to stick MyToken header in all applications and monitored with Fiddler2. I saw the header, but MyIdentityAsserter is not always invoked; not in my application of test and not during the connection to the admin console.
  
  Then I changed "MyToken" in "User-Agent", so that it is always present. Hitting a page protected in my test application went directly to the login form; However, this connection to the console admin time called assertIdentity().
  
  Why is this? What I am doing wrong? Y did he do any scope of particular debugging I can turn on to see what decisions WLS? I already lit atz and DebugSecurity but I don't see anything relevant in the newspapers.

  Power off or fast reset is not the same as cold-reset/reboot. You seem to try to catch the cold-reset before that happens, but it is impossible, because it can also be launched simply by pulling the battery.

• 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!

  }
  

  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!

• GPS problem

  Dear,

  According to instrucations here:

  'Retrieve a single fix.

  I added the code in the cpp file, added "LIBS +=-lQtLocationSubset" in my file pro

  and the location enabled in the describtor

  but I am facing problem in the .h file

  private Q_SLOTS:
      // This slot is invoked whenever new location information are retrieved

  I added understands that

  #include

  so, what's the problem?

  Can someone help me?

  QGeoPositionInfo is located in the QtMobilitySubset namespace.

  Try replacing the positionUpdated line with:

  void positionUpdated(const QtMobilitySubset::QGeoPositionInfo &pos);
  

• GPS position updated connected question

  Dear,

  I now try to get my current location

  According to instrucations here:

  https://developer.BlackBerry.com/Cascades/documentation/device_platform/location/retrieving.html

  and my post here

  http://supportforums.BlackBerry.com/T5/Cascades-development/GPS-issue/m-p/2483917#M27417

  I've solved the problem and the code works without error,

  But when I call

  bool positionUpdatedConnected = connect(src,
              SIGNAL(positionUpdated(const QGeoPositionInfo &)), this,
              SLOT(positionUpdated(const QGeoPositionInfo &)));
  

  I had

  positionUpdatedConnected  = false
  

  Can someone help me why this result?

  Thank you.

  Hello

  As Zmey pointed out in your other post, you must modify the declaration of your location of positionUpdated() in your GPs.h file. You must rework so that you do not need to specify the QtMobilitySubset namespace (as in your cpp file):

  private Q_SLOTS:
      // This slot is invoked whenever new location information are retrieved
      void positionUpdated(const QGeoPositionInfo &pos);
  

  To do this, put a using statement in your GPs.h file, which unfortunately is not always desirable. You could put

  using namespace QtMobilitySubset;
  

  But if you're worried about having "using" in your header file, you can limit the scope of what you need if you put

  using ::QtMobilitySubset::QGeoPositionInfo;
  

  These changes are necessary due to the nature of the connect() method. In my view, than it does not much more than the chain by comparing the quantities in SIGNAL() and SLOT() macros. The method parameters must match each other and how the methods are declared in their respective headers.

  As you can see I have connected the signal postionUpdate() of QGeo class that I use for the positionUpdatedSlot() of the slot. I use the class as follows:

  Pop = new GPShandler (this);

  void::startTimer() {} App

  Pop-> start();

  }
  void::stopTimer() {} App

  Pop-> stop();

  }

  which are called when a key is pressed. However, the positionUpdatedSlot() of slot function is never called. I have debugged in my code and cannot find the problem. I can confirm the work of connection (function returns true), and that presented startup and shutdown functions are called as expected. Is there a reason why my slot machine function is not called?

  Note: I have another implementation of signal/slot in this app:

  Connect (mTimer, SIGNAL (timeout ()), this, SLOT (update ()));

  and it works very well.

  Thank you

  Gerry

  I do not know which of the following has solved my problem, but in any case, it's working now after doing these things:

  1. give permission to app to device identification information. (I had already given GPS, but examples also being device identifying information I thought I'd try that)

  2. remove the line:

         mGeo>setPreferredPositioningMethods(QGeoPositionInfoSource::SatellitePositioningMethods);
  

  as an example, I created using this example: http://blackberry.github.com/Cascades-Samples/geo-locationdiagnostics.html did not have this line

  This code works for me, you can set a lower accuracy in meters (better accuracy) to ensure that you get a good Postal Code. My guess is (precision< 100)="" should="" be="">

      double accuracy = pos.attribute(QGeoPositionInfo::HorizontalAccuracy);
      qDebug() << accuracy;
      if (accuracy < 2000) {
          double lat = pos.coordinate().latitude();
          double lon = pos.coordinate().longitude();

          if (!saved) {
  // This saved bool is needed because this slot gets called multiple time even after source->stopUpdates() is called. Initialize it to false in your constructor

• Object::connect: Not such an accommodation problem

  I have no idea why its happening. I extended QObject and also added the Q_OBJECT macro. Signal and two slot also has same parameter.

  It's my hpp file,

  /*

  public:
      QGeoAreaMonitor *monitor;
  };
  
  #endif /* LOCATIONMONITOR_HPP_ */
  

  It's my cpp file

  LocationMonitor::~LocationMonitor() {}
  
  void LocationMonitor::areaEnteredd(QGeoPositionInfo info)
  {
  }
  void LocationMonitor::areaExitedd(QGeoPositionInfo info)
  {
  }
  

  const and & can be omitted within SIGNAL / SLOT macros. If they are present, MOC will remove them anyway. Only non const references should be left as is.

  Try changing the statements of slot for:

  public slots:
      void areaEntered(const QGeoPositionInfo &info);
      void areaExited(const QGeoPositionInfo &info);
  

  Names of parameter types are generally complete in the signals, but QtMobilitySubset is an exception to this rule.

  A little more information on this: http://supportforums.blackberry.com/t5/Cascades-Development/GPS-Position-Updated-Connected-Issue/m-p...

  Connect them like this:

  QObject::connect(monitor, SIGNAL(areaEntered(QGeoPositionInfo)),this, SLOT(areaEnteredd(QGeoPositionInfo)));
  QObject::connect(monitor, SIGNAL(areaExited(QGeoPositionInfo)),this, SLOT(areaExitedd(QGeoPositionInfo)));
  

• Cannot invoke the picture editor

  I'm calling the standard image editor, but but failed. I use 10.3.2 API and testing my application on the Simulator.

  Here is my code:

  Inside the .pro file, I added libs:

  LIBS += -lbbsystem
  

  Inside the .bar file, I added the following permissions:

  access_shared
  

  hand. QML:

  import bb.cascades 1.4
  import bb.cascades.pickers 1.0
  import bb.system 1.2
  
  Page {
      ImageView {
          id: imageView
          scalingMethod: ScalingMethod.AspectFill
      }
  
      attachedObjects: [
          FilePicker {
              id: filePicker
              type: FileType.Picture
  
              onFileSelected: {
                  invocation.query.uri = "file://" + selectedFiles[0];
                  invocation.trigger("bb.action.EDIT");
              }
          },
  
          Invocation {
              id: invocation
  
              query {
                  invokeTargetId: "sys.pictureeditor.cardeditor"
  
              }
          }
      ]
  
      actions: [
          ActionItem {
              title: "Select Picture"
              ActionBar.placement: ActionBarPlacement.OnBar
  
              onTriggered: {
                  filePicker.open();
              }
          }
      ]
  }
  

  Debug gives me the next exit to start the application:

  InvocationWrapper::onQueryFinished: menu service population failed
    query mimeType=""
    query uri=""
    query data=""
    query metadata=QMap()
    query action= ""
    query target= "sys.pictureeditor.cardeditor"
    query perimeter= 0
  InvocationPrivate::onQueryResolved: query failed, no armed signal sent.
  

  What's wrong?

  After some tests, I can confirm that this call does not work in QML, it will work only in C++.

  Here is a code snippet

  applicationui.cpp

  void ApplicationUI::invoke(const QString& targetId, const QString& actionId, const QString& mimeType, const QString& uri, const QString& data) {
      qDebug() << "Invoke:" << targetId << actionId << mimeType << uri << data;
  
      InvokeRequest request;
      request.setTarget(targetId);
      request.setAction(actionId);
      request.setMimeType(mimeType);
      request.setUri(uri);
      request.setData(data.toAscii());
  
      // Start the invocation
      InvokeManager* invokeManager = new InvokeManager(this);
      invokeManager->invoke(request);
  }
  

  hand. QML

  onFileSelected: {
      _app.invoke("sys.pictureeditor.cardeditor", "bb.action.EDIT", "", "file://" + selectedFiles[0], "")
  }
  

• How to invoke the basic application of e-mail that sending emails to multiple receivers?

  Hello world:

  I want to call the application of basic messaging to send email to multiple(>3) receptors, but how to write the uri?

  both receivers of document see the e-mail addresses:

  mailto:[email protected][email protected]
  

  It's ok, it can be analysed at '[email protected]' and '[email protected]', but how do you send email of 3 or 4 addresses?

  There is another question: how to write the json type in 'QVariantMap '?

  {
    "to" : ["[email protected]", "[email protected]"],
    "from" : 1234,
    "cc" : ["[email protected]", "[email protected]"],
    "bcc" : ["[email protected]", "[email protected]"],
    "subject" : "Some punctuation. Symbol in the $ubject!!",
    "body" : "HI! Here is some more stuff.\n\n14% of emails have #1 newline or
  stuff* @ home.\n",
    "attachment" : ["file:///path/to/my/item.txt"]
  }
  

  Thank you very much!

  Thanks much alopix!

  mailto:[email protected][email protected][email protected]
  

  It works very well.   Thank you once again!

  But for the QVariantMap, I try like this, it doesn't work yet! Help, please!

      bb::system::InvokeManager m_invokeManager;
      bb::system::InvokeRequest m_request;
  
      m_request.setTarget("sys.pim.uib.email.hybridcomposer");

      //m_request.setUri("mailto:"+email);
  
      QVariantMap map;
      map.insert("to", QVariantList() << "[email protected]" << "[email protected]");    // required
  
      QByteArray requestData = PpsObject::encode(map, NULL);
  
      m_request.setData(requestData);
  
      const InvokeReply *reply = m_invokeManager.invoke(m_request);
      if (reply) {
          // Ensure that processInvokeReply() is called when the invocation has finished
          //QObject::connect(reply, SIGNAL(finished()), this, SLOT(processInvokeReply()));

• Problem with InvokeManager::invoked

  I use Invocation Framework as client and target.

  client works well.

  now added support to be relied on as a target.

  added to the handle bar:

  
          my-name
          assets/images/my-icon.png
          APPLICATION
          
              bb.action.OPEN
              image/png
              .... some more
          
      
  

  Using the application InvocationClient Cascades - community - samples to Github, I can ask my app, app will be found and also launched or opened.

  If the app is known as a target and the filter works as expected.

  But I don't get the InvokationRequest in my SLOT:

  PPS:

  private Q_SLOTS:
    void handleInvoke(const InvokeRequest& request);
  

  CPP:

  void MyApp::handleInvoke(const InvokeRequest& request) {
    qDebug() << "Invoke Request to handle";
  }
  

  debugging and found that the connection has not been made.

  This is my login code:

  m_invokeManager = new InvokeManager(this);
      ok = connect(m_invokeManager, SIGNAL(invoked(const InvokeRequest&)), this, SLOT(handleInvoke(const InvokeRequest&)));
      if (!ok) {
          qDebug() << "connect handleInvoke failed";
      }
  

  Failed to connect with:

  Object::connect: No such signal bb::system::InvokeManager::invoked(const InvokeRequest&)
  

  no idea what could be the problem?

  Probably need to namespaces... try this

  _invokeManager = new InvokeManager(this);
      connect(_invokeManager, SIGNAL(invoked(const bb::system::InvokeRequest&)),this, SLOT(onInvoked(const bb::system::InvokeRequest&)));
  

• Maybe clicked on something that I should not have... Advice please!

  A window appeared on my browser (latest version of chrome on a MacBook of 2015 using the latest OS) which resembles an investigation legitimate from my ISP. Recently I had problems with them and my alarm has not extinguished quickly enough. It is curious that this window has appeared without an email but it didn't fully if register because my ISP has pop-up warnings apparently. I have NEVER had a pop up - but - due to some questions by e-mail, my firewall is down and I forgot to put up again.

  Yes, as the fog cleared I had already clicked through the investigation and he offered a free gift and that's when I realized that I should immediately stop the window. I haven't entered ANY info, never filled out a form, or I don't have to download anything. I installed Malwarebytes for Mac and he came clean.

  My concern: could I have gotten something malicious as a key logger or some other identity stealing malware simply by clicking on the poll? I think they call it a drive by?

  I'm a meticulous time machine user, so I have a complete backup of 99% of my system hard disk external. I should burn the Earth just to be sure?

  ... I haven't entered ANY info, never filled out a form, or I don't have to download anything.

  Then you have no reason to worry.

  Could I have gotten something malicious, as a key logger or some other identity stealing malware simply by clicking on the poll?

  Keylogger No.. At for example requires authentication to install.
