• Access the method of class (impl) view of bean object (or vice versa)

  Halo everybody, I use JDeveloper 11.1.2.1.0
  
  I use a UsersViewImpl class with a method that update the table as below.
  
  public void resetEmployeeSearch() {}
  removeApplyViewCriteriaName ("viewCriteria");
  executeQuery();
  }
  
  and I have a UserBean class with a method that reset the values of fields of research such as below.
  
  {} public void resetInput (ActionEvent actionEvent)
  ........ RichInputText = entry...
  input.setValue("");
  AdfFacesContext.getCurrentInstance () .addPartialTarget (searchForm);
  ........
  }
  
  
  I want to implement that, once I press a button, the two methods are called.
  
  I tried to call method of bean using vs UsersViewImpl = new UsersViewImpl... who does not and will not work.
  I've read about something as ViewObject vo = am.findViewObject ("DeptView1") but I duno how to use because I can't have a good example.
  
  Any suggestion on access to the method of class (impl) view of bean object (or vice versa)?
  Or is it possible to combine the two method in the same class?
  
  
  Thanks :(

  and then create a link to this effect in your page. > Sorry, dun get this part. You create the link from the button to the UsersViewImpl method?
  The code below should be method (binding) in UsersViewImpl, right?
  OperationBinding op = ((DCBindingContainer) BindingContext.getCurrent () .getCurrentBindingsEntry ()) .getOperationBinding ();
  op. Execute();

  What I meant to say call this code your method of bean... this way you can call both the logic in your bean and the method of VO together!

• How to call the method of bean of support on the component date. MinValue

  Hello

  I have a method in bean

  {} public void sample()

  Set the entry code

  }

  I want to call the sample method when I click the date component. MinValue in .jsff

  Right now using the < af:clientListener method = 'onClick' type = "click on" / > inside the < af:inputDate > element

  < af:resource type = "javascript" >

  function onClick (clickEvent) {}

  Alert ("hiii");

  Here, I want to call the sample method by clicking on date. MinValue

  }

  < / af:resource >

  Any Solution would be Appreciable

  Try to follow this:

  -Inside af: inputDate add clientListener and serverListener

  The serverListener method must map to a function in backbean

  -in java script method write this

  function onClick(event)
  {
    var source = event.getSource();
    AdfCustomEvent.queue(source,"serverListenerOperations", {}, false);
  }
  

• How to call the method of notification service websocket project different from the same application?

  Hi all

  My problem:

  * I have ADF application with model, view and websocket service inside projects.

  * I wish to inform the client (browser) on event triggered in the model project.

  * So, I need somehow to invoke the websocket service method to send the message to all the sessions that are enrolled in the websocket communication channel.

  * How can I achieve that?

  I use JDev 12.1.3 with built-in WebLogic Server. Thank you!

• How to call a method of the Module of the Application of a class of ViewObjectImpl?

  Howdy,
  
  With the help of Studio Edition Version 11.1.1.3.0.
  
  I have a setup where a user between an element and a price. When the item and the price is committed, I want this event to then influence the price of his parents. My idea is to do a ViewRowImpl class and then call an AppModuleImpl class that is her parents and it affects their attributes.
  
  Question:
  
  (1) how to call a method on the Module of the Application of a class of ViewObjectImpl?

    public void setPrice(Number value)
    {
      setAttributeInternal(PRICE, value);
      
      DCBindingContainer bindings = (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
      BindingContext bctx = bindings.getBindingContext();
      DCDataControl control = bctx.findDataControl("AppModuleDataControl");
      ApplicationModule am = (ApplicationModule ) control.getDataProvider();
      //uh now what??
      // am.getProperty("method call(getTipsNum())") ?
    }

  (2) when I set an attribute on a view through the AppModuleImpl object, I'll make an infinite loop in this way? that is the AppModuleImpl calls the ViewRowImpl class on a setAttribue (< name >, < value >)?
  
  Thank you guys.

  It's an interesting problem, I'll take a stab to solve here.

  First let's see I understand the data model:

  (a) there is a table called BOM with a self referencing FK creating a hierarchy of data
  (b) each record BOM is usually a child to another record BOM, so using your example, a van is composed of frames and tires - Let's say that this amounts to 3 records in the Schedule table.
  (c) check parent, truck, is the root of the hierarchy, and so the FK relationship sucks.
  (d) the price of a truck consists of its children. So if the frame costs $1,000 and tires $500, the pickup truck costs total $1,500.
  (e) a change in the price of any folder BOM, upwards or downwards must be propagated to its parent folder BOM. As an example, if the tires up to $600, the pickup truck is now $1600 ($1000 frame + tires $600).

  Does this sound right?

  Well, that I understand the data model, here's what I'd do build in what concerns objects ADF BC:

  (1) an entity BOM (EO) object - let's call this Bom
  (2) a BOM BOM EO association (representing the self referencing FK)-Let's call it BomBomFkAssoc
  (3) an object to view BOM (VO) based on the EO - let's call it BomView
  (4) BOM VO view link BOM VO based on EO of #2 association - call BomBomFkLink

  Next, we create the Java constructs:

  (5) #1 ensures that the EntityImpl has been created
  (6) #4 guarantees for the EO association that it generates the required Java accessors

  Now the additional code:

  (7) for the EntityImpl # 5, in the field of setter setPrice() something like the following:

  public Number setPrice(Number value) {
    Number diffPrice = value.minus(getPrice()); 
  
    setAttributeInternal(PRICE, value);
  
    BomImpl parentBom = getBom(); // from step #6, the EntityImpl should have an accessor method to it's parent BomImpl record
    Number parentDiffPrice = parentBom.getPrice().add(diffPrice);
    parentBom.setPrice(parentDiffPrice);
  }
  

  From a point of view JSF, now when I change a specific record of the Nomenclature in an edit form, a change for the price of registration for the Bill to submit time will automatically propagated to the top of the hierarchy of the BOM because the method setPrice() of the current OS of BOM will walk to the top of the hierarchy of the BOM to the parent following the call it is setPrice() method , which will be then walk to the next BOM record and so forth. At the time all BOM records with changes should be committed to the database.

  You don't need to test this in JSF, but simply the browser component of company on the Application template project Module.

  .... Of course... If I misunderstood your data model, it will be of no help whatsoever.

• 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

• 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
  

• How to call a method abstract in Java

  Hi all

  I am new to Java, and have been learning. I have a question here. I came across the following Java class and trying to understand but got confused how he is able to call an abstract method. Here's the code I'm referring to:

  package sampleapps.gui;

  Javax.swing import. *;

  import java.awt.*. *;

  public class InnerClassAnimationExample {}

  int x = 70, y = 70;

  Public Shared Sub main (String [] args) {}

  InnerClassAnimationExample innerClassAnimationExample = new InnerClassAnimationExample();

  innerClassAnimationExample.go ();

  }

  public void getCurrentCard {}

  JFrame frame = new JFrame();

  frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);

  NewMyDrawPanel drawPanel = new NewMyDrawPanel();

  frame.getContentPane () .add (drawPanel);

  frame.setSize (300, 300);

  frame.setVisible (true);

  for (int i = 0; i < 500; i ++) {}

  x ++ ;

  y ++ ;

  drawPanel.repaint ();

  try {}

  Thread.Sleep (50);

  } catch (Exception e) {}

  e.printStackTrace ();

  }

  }

  }

  class NewMyDrawPanel extends JPanel {

  {} public void paintComponent (Graphics g)

  Graphics2D g2d = (Graphics2D) g;

  Red int = (int) (Math. random() * 255);

  int green = (int) (Math.Random () * 255);

  Blue int = (int) (Math. random() * 255);

  Color startColor = new color (red, green, blue);

  Red = (int) (Math. random () * 255);

  Green = (int) (Math.Random () * 255);

  Blue = (int) (Math.Random () * 255);

  Color endColor = new color (red, green, blue);

  GradientPaint gradient = new GradientPaint (7070, startColor, 150 150, endColor); We can also use colors straight as Color.RED, Color.BLUE

  GradientPaint gradient = new GradientPaint (7070, startColor, 150 150, endColor);

  g2d.setColor (Color.White);

  g2d.fillRect (0, 0, this.getWidth (), this.getHeight ());

  g2d.setPaint (gradient);

  g2d.fillOval (x, y, 40, 40);

  }

  }

  }

  For example, in the code above, there are an internal NewMyDrawPanel class that has a method paintComponent (Graphics g). I've highlighted the 2 lines of code above.

  Line 1 : Graphics2D g2d = (Graphics2D) g;

  Line 2 : g2d.fillOval(x,y,40,40);

  
  

  I understand that we are casting type reference to Graphics2D g reference g2d and we call the method fillOval() on g2d. I do not see a method of fillOval() in the Graphics2D class but it's there in the Graphics class and Filloval()) method is an abstract method.

  So my question is:

  1. If we are not able to instantiate an abstract class (Graphics2D Graphics classes) and how are we able to access the abstract method fillOval()

  2. Secondly, given that the fillOval() method is an abstract method, it has no implementation for the method. However, when I call the method fillOval() on Graphics2D reference, I was able to draw and fill in an oval of the specified coordinates. Then, where the actual implementation code would be?

  Could you please, somebody explain how this happened? Pls help.

  Thanks in advance.

  The point of having the Graphics class declaring fillOval() summary, is that we can have confidence that all the graph goes instantiable subclass is an implementation of this method. You as the user of this unknown implementer of graphics have no need of care including probably several classes in this legacy hirarchie did the implementation. You just trust in the fact that it must be there, because the java compiler takes care of this.

• Call the method call activities before you navigate to the target jsf page

  Dear all,

  I use JDeveloper Studio Edition Version 12.1.3.0.0.

  Requirement:

  I have a stubborn taskflow. The stubborn workflow is without using page fragments.

  I have three pages: login.jsf, admin.jsf, user.jsf. I have a method call activity in the taskflow. The login.jsf is the default page. The page of login.jsf have an af:selectOneRadio with two af:selectItem: Admin and user. It also has an af:button. When the user select the af: af selectItem: selectOneRadio and click on the af: button, it should call the method call activity (doLogin) and based on logic it will redirect to the page admin.jsf or user.jsf page.

  Please find the taskflow below:

• 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

  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.
