• 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.

• 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
  

• Call stored procedures in the object module and application of entity

  Hello
  
  I've implemented a helper methods that contains the EntiyImpl base class to call stored procedures.
  
  Now, I need to call procedures stored from the module of the application.
  
  Apart from the creation of a module base class asks and the programme of assistance of duplication of code in the method is possible
  to share methods of assistance for calling stored procedures between the entity impl and application module impl?
  
  
  Concerning
  Paul

  Support code depends on characteristics of an object instance given entity beyond its database transaction?

  If so, I'm not sure I see how it could be used with a class of application module.

  Otherwise, here's what you do:

  Step 1:

  Set up the database transaction - you can even choose to. So instead of

  {myHelperMethod (Object someParam) protected
  DBTransaction trans = getDBTransaction();
  ...
  }

  This is for change

  protected myHelperMethod (DBTransaction trans, someParam Object) {}
  ...
  }

  Step 2: make the method public and static - once you set DBTransaction, you should be able to do.

  public static myHelperMethod (DBTransaction trans, someParam Object) {}
  ...
  }

  Step 3: Remove your EntityImpl base class method in a utility class:

  Public MustInherit class PlSqlUtils {}
  private PlSqlUtils() {}

  public static myHelperMethod (DBTransaction trans, someParam Object) {}
  ...
  }
  }

  When you call the method of application module, object entity or class of same view object, call

  PlSqlUtils.myHelperMethod (getDBTransaction (), paramValue);

  Unlike Transaction.executeCommand (), allows you to provide features like the setting procedure of parameter values, recovery of the values of the parameters, etc.

  Hope this helps,

• Call the method from another application

  Then. That is my question. Is it possible to call a method from another application, so I can get some data from this app?

  I know that I could also do this with persistent store, but I would like to do it this way.

  Thank you. I'll try with world events and TIME store.

• View module update shared application instance

  Hi all

  I have a read only display within a module of the shared application.

  i sometimes I need to update from this point of view I put the property of auto-refresh to true and the big change for the user for example (GRANT CHANGE NOTIFICATION to HR),but he has still not updated my opinion

  all ideas

  Best regards

  I solve this problem by writing code in the shared application Impl module

  This is the code:

  ViewObjectImpl vo = this.getDepartmentsView1 ();

  Manage = Configuration.createRootApplicationModuleHandle

  (model ".") SharedAM', 'SharedAMLocal');

  Sam ApplicationModule = handle.useApplicationModule ();

  sam.processChangeNotifications ();

  Line = vo.createRow ();

  .

  .

  .

  .

  Configuration.releaseRootApplicationModuleHandle (handle, false);

  vo.executeQuery ();

• A method that runs when an application is called in the foreground?

  Just back to Java after a year of Action Script only and trying of don't forget do not put "var" in front of my variables. In any case, I remember to do that just do not remember how. My application runs in the background, how do I run a power supply... uh... method every time that the application is in the foreground? I use a right headphone?

  Yes, that's correct.

• Custom method in the Module of the Application with parameter

  Hello
  
  I created a custom in my AM method that takes a parameter map m as input.
  
  {} public void dosomething (map m)
  ... my stuff...
  }
  
  In my jspx to executables and links page, I have added my method as a "methodaction."
  and some "dosomething (Map)" in the menu dropdown called operations.
  Down to settings, I see the current map.
  
  But when I call the method of the bean of my support, like this:
  BC = (DCBindingContainer) getBindings ();
  OperationBinding opb = (OperationBinding) bc.getOperationBinding ("dosomething");
  opb.getParamsMap () .put ("dosomething", my_map);
  OPB. Execute();
  
  the card remains in the AM zero...?
  The card is not set?
  
  Anyone who could help me with that?

  opb.getParamsMap () .put ("* m *", my_map "");

  Instead of the name of the method, I think it should be the name of the parameter.

  Why not put it in the Pagedefinition. It would be a good practice.

  Kind regards

• Modules and Applications / user uninstall

  [Tank, 4.5.x]

  A few questions:

  (1) my request is listed under 'modules' not 'applications '.  I guess that's because it is autostart?

  (2) there is apparently no way for the end-user to 'delete' a module?

  (3) is there a way for the user to do a uninstall rather than Options! Advanced! Apps! (Modules)

  (4) for uninstalling (assuming I can get it done, or via "javaloader erase"), are persistent automatically deleted stores?

  (5) is there a way for my application get called with a switch "/ Uninstall" or something, so I can delete files, etc. ?

  The app will OTA provisioned (pull the Web) and will not have access to the Javaloader, etc..

  Is there a document of so that I can RTFM? (Sorry the forum are a little laggy for me at the moment).

  Thank you

  Files don't go away if you uninstall via Options > Advanced > Applications. I am facing the same issue and my approach (not yet implemented) is to add a function to uninstall the application itself. The application can use CodeModuleManager to do the same thing (including to request the reset of the device) which is made by removing the application via the Options.

  BlackBerry specific persistence methods (persistable and runtime store) are not limited to 64 KB or said by the way. (And in 4.6 or later version, the limit is 512K).

  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.

• want to access a module of application of a class in a web application

  Hello
  
  We want to convert our projects of 10g 11g and previous code that no longer works. I need to access an application from a managed bean module. The code we used in 10g is as follows:
  
  public String getEnvironmentVariable() {}
  
  String varenv;
  FacesContext fctx = FacesContext.getCurrentInstance ();
  Application app = fctx.getApplication ();
  Binding DCBindingContainer = (DCBindingContainer) app.getVariableResolver () .resolveVariable (fctx, "bindings");
  DCDataControl dcCtl = binding.findDataControl("CashDrawerAMDataControl");
  CashDrawerAMImpl am = (CashDrawerAMImpl) dcCtl.getApplicationModule ();
  ViewObject vo is am. ArcontrolForEnvVar();
  VO. First();
  varenv = (String) vo.getCurrentRow () .getAttribute ("Environment");
  Return varenv;
  
  }
  
  but the getVariableResolver (.resolveVariable) methods are now deprecated.
  
  Does anyone know what I should be using now?
  
  Thank you
  Lana

  : Iana,

  Here is the information you need

  http://blogs.Oracle.com/smuenchadf/examples/#152

  To access an application method of your support bean are:
  -create the method in AM
  -expose the method on the client interface
  -Add action liaison to def page, who runs the AM method
  -in managed bean research links def and run action binding

  PS - If it's only to call a method of the AM, most of the time won't you even need a bean of support (try and restrict the use of these to where you need to specifically manipulate certain aspects of the user interface)-just drag Am method on the page as a command button and the coding is done for you :)

  See you soon,.

  I have read and watched videos about the creation of an object of a class and calling its method in a different class. I'm still confused on how to do it properly. By using the code below if someone can explain how to properly call the method of objects from my hand.

  Huh? You have NOT posted any 'hand' or any 'method of objects '.

  If you need help with the code, you need to view the code.

  The Java tutorials has dozens of trails "Classes and objects": what they are, how to create and how to use them.

  https://docs.Oracle.com/javase/tutorial/Java/javaOO/classes.html

  1. create an instance of a class

  2. call to one or more of the public methods of this class

  If the class has public static methods, you don't need to create an instance first.

  I suggest that you work your way through these tutorials. They include the WORKING example code.

• Error when calling a method AM of Bean managed

  Hi friends,

  JDev's Studio Edition Version 11.1.2.4.0

  I have a page (HomePG) that has a read-only table. Select a field in the table and you enter a value for the inputText and then clicking on a button, the selected employee's salary should be replaced by the value entered in the inputText field.

  I am trying to call a method of the managed bean AM and I get an error while doing this. I created a link to the method in the page where the call is made.

  Here is the code of the AOS

  ' Public Sub hikeSelectedRow (Key key, BigDecimal val) {}

  ViewObjectImpl emp = getEMPVO1();

  RowSetIterator empVO = emp.createRowSetIterator ("Test");

  System.out.println ("in selected Update");

  System.out.println ("in selected, Update key:" + key);

  Row [] selectedEmpArr;

  selectedEmpArr = empVO.findByKey (key, 1); -> Error comes here

  System.out.println ("in selected, Update key:" + key.toString ());

  EMPVORowImpl selectedEmp = (EMPVORowImpl) selectedEmpArr [0];

  selectedEmp.setSal (selectedEmp.getSal () .add (val));

  System.out.println ("added, made Bravo");

  getTransaction () .commit ();

  }

  The line is selected in the Managed bean and is also selected. However during appraisal findByKey get the performance I get the below error. Can someone please.

  The error I get is

  < ActionListenerImpl > < processAction > java.lang.NumberFormatException: for input string: "[oracle.jbo.Key [7566]].

  javax.faces.el.EvaluationException: java.lang.NumberFormatException: for input string: "[oracle.jbo.Key [7566]].

  KeyVal key = new key (new Object() {Integer.parseInt (((List) tableIterator.next ()) m:System.NET.SocketAddress.ToString ())});

  So, what will return: (tableIterator.next ()) m:System.NET.SocketAddress.ToString () (list)?

  I suppose this relates a strange string?

  Check out this blog for a correct use of the RowKeySet (and is also described in a easier way to get the current line in the case of single selection): ADF:TABLE - Get selected or lines. John Brunswick

• 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.

  Good bye
