• How to call a method of the AM with parameters of Bean managed?

  Hello world
  
  I have a situation where I need to call the Managed bean (setDefaultSubInv) AM, under value changes Listner method. Here's what I do, I added the AM method on page links, and then at the bean call it
  
  Class [] paramTypes = {};
  Object [] params = {};
  invokeEL ("#{bindings.setDefaultSubInv.execute}", paramTypes, params);
  
  It works and be able to call this method, if there are no parameters. Say that I pass a parameter to setDefaultSubInv(String a) method AM, I tried to call it bean but raise an error
  
  The string available = 'test ';
  Class [] paramTypes = {String.class};
  Object [] params = {DISP};
  invokeEL ("#{bindings.setDefaultSubInv.execute}", paramTypes, params);
  
  I'm not sure this is the right way to call the method with parameters. Can anyone tell how to call a method of the AM with bean to manage settings
  
  Thank you
  San.

  Just do the following

  1. your method in the Client Interface.
  2 - Add to Page Def.
  3 - Customize your Script like below one to reach your goal.

  BindingContainer links = getBindings();
  OperationBinding operationBinding = bindings.getOperationBinding("GetUserRoles");
  operationBinding.getParamsMap () .put ("username", "oracle");
  operationBinding.getParamsMap () .put ("role", "F1211");
  operationBinding.getParamsMap () .put ("Connection", "JDBC");
  Object result = operationBinding.execute ();
  If (! operationBinding.getErrors () .isEmpty ()) {}
  Returns a null value.
  }
  Returns a null value.
  }

  I hope it helps you
  Thank you

• How to call a method defined in AM when I select a value in LOV

  Lets say there is a LOV. The scenario is as soon as I select a value in LOV, a method should be called I wrote in the AM. And the output of the method in an output text area.
  
  I am not able to understand how to call a method when the user selects a value from the LOV.
  
  
  This is wht I did. I had created the connection for the method. One replaced the property autosubmit to the LOV for real and in the properties of the output area, in partial submission trigger property, the ID of the LOV. But I don't have any place where I need to call the method. I'm also not able to remove a listener for action on the LOV
  

• question on "How to call a method once when starting the application"

  Hello everyone.
  
  I'm trying to implement that article "How to call a method once when you start the application" by Frank suggests.
  https://blogs.Oracle.com/jdevotnharvest/entry/how_to_invoke_a_method
  
  
  Suppose I want to have a single entry point, so in my login.jpsx I have the below:

  <f:view beforePhase="#{login.onBeforePhase}">

  In the 'onBeforePhase' method, I have to pass the phaseEvent, since the signature is as follows:

  public void onBeforePhase(PhaseEvent phaseEvent)

  But how do I know the phaseEvent during the call to the login.onBeforePhase? How the call should be?
  
  Thank you very much!
  
  
  PS. I use jDev 11.1.2.1.0

  You must not pass something to this method, this method is called before each Phase except view restoration
  Just write logic as Frank suggested to the phase in which you want the code to run. You can get the PhaseId analogues

  PhaseId.RENDER_RESPONSE

  public void onBeforePhase(PhaseEvent phaseEvent) {// from Frank's doc
   //render response is called on an initial page request
    if(phaseEvent.getPhaseId() == PhaseId.RENDER_RESPONSE){
  ... etc

  ADF7,
  the subject of the post has nothing to do with the question (for as far as I see it).
  As you can see the error message clearly comes from the procedure pl/sql you call the application module, works of groovy appeal method.

  We cannot decide what makes your service if you pass null as a parameter. You can check the settings before you proceed to the procedure or write the procedure in how it treats null parameters.

• How to call other functions within the ScriptableFunction class

  I am trying to create an extension of javascript class which will record audio, but the problem is that I can't call other methods in the class.

  clear explanation about my problem:

  It's my Scriptable class

  public final class OCNUtilsNamespace extends Scriptable
  {
      VoiceRecord vr;
  
      public OCNUtilsNamespace()
      {
          this.vr = new VoiceRecord();
      }
      public Object getField(String name) throws Exception
      {
          else if(name.equals("VoiceRecorder")){
              return this.vr;
          }
  
          else if (name.equals("stopRecording"))
          {
              this.vr.stopRecording();
              return new String("Stopped Recording");
          }
          else if (name.equals("startRecording"))
          {
              this.vr.startRecording();
              return new String("Started Recording");
          }
          return super.getField(name);
      }
  }
  

  and here's my ScriptableFunction class:

  public class VoiceRecord extends ScriptableFunction {
  
      String status = "start";
      public Object invoke(Object obj, Object[] args) throws Exception{
          if(status.equals("start"))
              return new String("Started Recording");
          if(status.equals("stop"))
              return new String("Stopped Recording");
          return new String("nothing");
      }
  
      public void stopRecording(){
          status = "stop";
          return;
      }
      public void startRecording(){
          status = "start";
          return;
      }
  }
  

  in my javascript every time I call

  alert(OCN.OCNUtils.VoiceRecorder());
  

  I get the response as "recording started"

  but whenever I tried to call

  alert(OCN.OCNUtils.startRecording());
  

  I don't get all respose and the script will stop working at that time here.

  Why is happening like that?

  I'm doing something wrong?

  I did not understand this concept of scriptablefunction anyone please explain what is happening?

  have to apply Runnble to the future because I have to record the sound of the microphone

  I suggest that you simply pass an argument of your javascript in your extension like this:

  public final class OCNUtilsNamespace extends Scriptable
  {
      VoiceRecord vr;
  
      public OCNUtilsNamespace()
      {
          this.vr = new VoiceRecord();
      }
      public Object getField(String name) throws Exception
      {
          if(name.equals("VoiceRecorder")){
              return this.vr;
          }
          return super.getField(name);
      }
  }
  

  and on your class that extends a ScriptableFunction,.

  public Object invoke(Object obj, Object[] args) throws Exception{
  
                 String param = args[0].toString(); // Cast a parameter from your js to a string
  
          if(param.equals("start"))
              return startRecording();
          if(status.equals("stop"))
              return stopRecording();
          return new String("nothing");
      }
  
      public String stopRecording(){
          status = "stop";
          return status;
      }
      public String startRecording(){
          status = "start";
          return status;
      }
  

  Finally, call your extension via javascript like this:

  alert(OCN.OCNUtils.VoiceRecord("start")); // Call the startRecording() on your VoiceRecord class
  alert(OCN.OCNUtils.VoiceRecord("stop")); // Call the stopRecording() on your VoiceRecord class
  

  Hope this helps

• How to call a method of itemRenderer

  Hello

  I need to call a method when the click on an HBox in DataGrid. However, when I try to call the method on click Control HBox property, an error appears stating "call to a goToAlertTab possibly undefined method." I duly defined this method within the tag < mx:Script >. Here is the code example. Is someone can you please tell me what is the problem?

  < mx:DataGridColumn headerText = "Alerts" dataField = "alert" >
  < mx:itemRenderer >
  < mx:Component >
  < mx:HBox horizontalGap = "2" horizontalAlign = "center" click = "goToAlertTab ()" >
  < mx:Canvas height = "100%" backgroundColor = "Red" alpha = "0.8".
  Width = "{Data.Alert.Critical}" toolTip = "{" criticism:'+ data.alert.critical "}" > "
  < mx:Label text = "" / >
  < / mx:Canvas >
  < mx:Canvas height = "100%" backgroundColor = "0xff6600" width = "{data.alert.error}" toolTip = "{'Error:'+ data .alert .error}" > "
  < mx:Label text = "" / >
  < / mx:Canvas >

  < mx:Label text = "" / >
  < / mx:Canvas >
  
  < / mx:HBox >
  < / mx:Component >
  < / mx:itemRenderer >
  < / mx:DataGridColumn >

  It is obvious that it is very difficult to go throw your hierarhy to change tab, event dispatching easier.

  It http://www.adobe.com/devnet/flex/articles/itemrenderers_pt1.html is a good example on the distribution of the itemRenderer events handling them.

  Can be also useful that you can use to navigate through the application. Read the docs to learn more about them.

  Download the product can be done immediately, however if you bought the subscription, you must wait to activate the product until the payment goes through, and the same goes for a perpetual license product once the payment goes through you will receive your serial number to activate the product.

• How an applet instance can call a method in the context of the proceeding one another?

  Consider an applet Java Classic Card with multiple instances that need to share data in a variable byte [] (e.g. persistent mutable, i.e. EEPROM/Flash), containing information common to all instances.
  
  Variable static ubyte [] would be perfect, but these happen to be prohibited by the validation rules imposed on me (I am told: as a way to tote to show that UN-instantiating an instance releases this she distributed on instantiation).
  
  This would be solved if an instance of the slave could call one of the method of the applet in the context of an instance of master (perhaps initially identified by AID, or/and/then in another way). How is that possible? Any example?

  Hello

  So I think that you don't need other assistance,

• How to pass the value calculated with the method of the Application Module?

  I am a newbie to ADF. IThink I'm missing something very basic:
  
  
  
  In JDeveloper 10.1.3.3 ADF, I'm trying to pass the session ID to a method in my App Mod, but the method receives a null value. I think I have a session ID getting too late in the process, but don't know where else to get it.
  
  
  
  Here are the details:
  
  
  
  I'm passing 3 argument to a method called ProcessReport:
  
  
  
  public String ProcessReport (Number reportNumber, Double caratWeight, String sessionID)

  OperationBinding operationBinding = bindings.getOperationBinding("ProcessReport");
  
  Object result = operationBinding.execute ();
  
  If (! operationBinding.getErrors () .isEmpty ()) {}
  
  Returns a null value.
  
  }
  
  
  
  String resultStr = (String) result;
  
  Return resultStr;
  
  
  
  No chance! I think I should get the sesson ID earlier, during the loading of the page, but I don't know where to put the code.
  
  
  
  Any suggestion would be appreciated.

  Hello

  Here's what I'd do

  1. create a bean managed as follows

  import javax.faces.context.ExternalContext;
  import javax.faces.context.FacesContext;
  
  import javax.servlet.http.HttpSession;
  
  public class HTTPSessionAccessBean {
  
      public HTTPSessionAccessBean() {
      }
  
      public void setHttpSessionId(String httpSessionId) {
      }
  
      public String getHttpSessionId() {
  
          FacesContext ctx = FacesContext.getCurrentInstance();
          ExternalContext ectx = ctx.getExternalContext();
          HttpSession mySession = (HttpSession) ectx.getSession(false);
          String sessionId = mySession.getId();
          return sessionId;
      }
  }
  

  2. in the ApplicationModule Impl class to create the following method and expose it as a clientInterface

      public void setSession(String sessionId){
         ((SessionImpl)this.getSession()).getEnvironment().put("http_session",sessionId);
      }
  

  (3) in the file for pageDef create method as binding

  (4) in the same file for pageDef create an invokeAction

  The session ID is now accessible from the ApplicationModule as

          Hashtable env = ((SessionImpl)this.getSession()).getEnvironment();
          String sessonId =(String) env.get("session);
  
          }
  

  This keeps the layer of model/view separation

• Calling a method in a Module sharing application

  I have a shared application module that has a custom method that uses data from the AM shared decision.
  
  The method will be put to the criteria (in code) to the results of the different 3 objects in view filter.
  
  If all users access the same method is the custom method must be synchronized?
  Since it is a single method, will be accessible to all users there be a performance problem?

  The answers are YES and YES according to how often access you the service method.
  If you call it frequently, you are better off putting the service method in a module of the normal application.
