How dynamic binding implemented?

for exmaple
abstract class SuperClass{
      abstract void do() {}
      class SubClass1 extends SuperClass{
      void do(){//do method implemented}
      class SubClass2 extends SuperClass{
      void do(){//do method another implemented}
      SuperClass[] array = new SuperClass[2];
           array[0] = new SubClass1();
           array[1] = new SubClass2();
           array[0].do();
           array[1].do();
I want to know how the compiler deal with "array" during compiling time,
and how the dynamic "do()" method was found during runing time?

You can get some hints by studying the bytecodeof
your example.
Generally dynamic binding is implemented using
indirect calls via "jump tables". Binding means
filling in the jump tables with the startaddresses
of
the methods as soon as they're available.~~~~~~~~~ this mean when instantiated?
Actually I took it to mean when the class is loaded.
Actually as soon as they are needed which isslightly
different. ~~~~~~~ this mean when the method invoked?Basically yes.

How to bind dynamic data to JNet

Develop tools: NWDS 7.1
Server: Windows2000
Does anyone have experiences with using JNET within Webdynpro Project ?
In our case, we use JNet to generate a hierachical network diagram in the Webdypro's GUI. The data source is from the tables in a DB. However, till now, we only know how to let JNet generate the network diagram from a static XML file.
Since the data in the DB changes all the time, how to let the network diagram reflect the newest data status automatically? That is, how to bind JNet to a dynamic data source then?

Hi,
Network UI element is related with Jnet. What you need to start up working with this is you need to create a context structure mentioned below.
Node:Source
Element--- xml -> this should be of type binary.
Place the following code in the init.
ISimpleTypeModifiable mod = wdContext.nodeSource().getNodeInfo().getAttribute("xml").getModifiableSimpleType();
IWDModifiableBinaryType bin = (IWDModifiableBinaryType)mod;
bin.setMimeType(new WDWebResourceType("xml", "application/octet-stream", false));
ISourceElement element =wdContext.nodeSource().createSourceElement();
wdContext.nodeSource().addElement(element);
try
fileName = WDURLGenerator.getResourcePath(wdComponentAPI.getDeployableObjectPart(), "jnettest.xml");
element.setXml(readFile(fileName));
catch (WDAliasResolvingException e)
You have to place the Jnet test.xml under the mimes folder of your application.
Place the network element in the view and in the data source specify the context attribute source.xml
if your xml file complies with the jnet schema your application will render it.
Pl go through this

How to understand dynamic binding

Hello all. I need some guidance on how to understand dynamic binding.
Here are my codes:
* fruit.java
public class fruit {
     public String type ="fruit";
     public String getType() {
          return type;
     public String getType2() {
          return getType();
* apple.java
public class apple extends fruit {
     public String type ="apple";
     public String getType() {
          return type;
     public String getType2() {
          return super.getType2();
* test.java
public class test {
     public static void main(String[] args) {
          apple myApple = new apple();
          System.out.println("myApple.getType2() : " + myApple.getType2());
}After running test.java I got myApple.getType2() : apple
I was told that it's because dynamic binding. I read some articles about dynamic binding but still do not understand how it works in my codes.

Dynamically binding backing bean

Dynamic binding of backing bean
Here is a problem that I have been trying to solve. Maybe someone can have a go at it:
Here is a Search form(Simplified version):
af:selectOneChoice - to choice a 'class family' e.g., companies, NGO, charity, institution etc
af:inputText - to enter a name
af:commandButton – to search
Here is a User task:
1.     Choose a 'class family' from the selectOneChoice
2.     Enter a name in inputText
3.     Click commandButton to start the search
Additional information
1. The number of 'class family' is about 30 and requires different method of search.
2. I want to use a uniform search user interface and so there is only one page for all.
3. Each 'class family' has it own managed bean in face-config.xml.
Scenario:
Lets say the searchUI.jsp has an initial backing bean called SearchBean.java. The af:selectOneChoice in searchUI.jsp has a valueChangeListener and when the user chooses a 'class family' at step (1), the valueChangeListener in SearchBean.java is triggered.
Problem:
The problem is how do I dynamically switch the backing beans, say from SearchBean.java to SearchCompanyBean.java so that when the user next click the search commandButton, it is the searchAction method in the SearchCompanyBean.java and NOT the initial SearchBean.java that handles the action.
Cheers in advance.

Hi,
Assuming you are using ADF BC, have a look at using view criteria. You can define, dynamically apply and remove view criteria on the view object.
Have a look at the help on oracle.jbo.ViewCriteria and applyViewCriteria from the ViewObject implementation class. Sounds like they might meet your requirements.
Create a client method on your VO and drag it onto your page as an ADF parameter form and go from there.

I do apologize if it's become sound like stupid or something . I know somehow it's not very suitable to think in that way but I was just thinking of the object reference variable as a pointer becauseA reference is like a "filtered" pointer to an object: it will only show that part of the object that corresponds with the type of the reference. So after "Fruit whatever = new Banana();", the "whatever" reference only shows the "Fruit" part of the "Banana" object. This means you can only call methods that are defined in Fruit, not those defined in Banana.
Dynamic binding means the JVM will decide at runtime which method implementation to invoke based on the class of the object. So, I thought
Fruit whateverFruit=new Banana(); and then if i tried to invoke whateverFruit.yellowBanana(); then the compiler will try to find the method out and executed automatically.That's not what it means. It means when you have "Fruit whatever = new Banana()" and you call "whatever.getName()", it will call the getName() method from Banana, if Banana overrides the implementation of Fruit. You can still only use methods that are defined in Fruit through a reference of type Fruit. In this case, it doesn't seem that the behaviour of setTypeOfApple() is different from setTypeOfBanana(), so ejp's recommendation to just create a setType() method in Fruit is correct.
Polymorphism means a variable of a superclass type to hold a reference to an object whose class is the superclass or any of its subclasses. So, I thought Fruit whateverFruit is somehow capable to hold the reference of its subclasses and can be used to reference of its subclasses. That's basically correct. However, the variable will only expose the superclass part of the subclass object.
I got confused with all those stuff and kinda lost. There's one more thing. What's the point of doing something like this Fruit apple=new Apple() if I can't reference to an instance of apple object ?? I mean I could just simply write like this Fruit aFruit=new Fruit(). Sorry, if i've become sound like a fool but i'm really confused. Please help me out of this and thanks in advance.The point of having any superclass/subclass combo is that your problem domain demands that you make the distinction: sometimes you need to be able to treat an object as Fruit, sometimes you need to be specific and treat it like an Apple. For example, if you sell fruit and need to calculate the total price of a fruit basket, all you need to know is that each piece of Fruit has a getPrice(), you don't need to know that one piece is an Apple and another piece is a Banana. However, if a customer demands a kilogram of apples, you need to make sure you give him only Apples and not Banana's.List<Fruit> fruitBasket = new ArrayList<Fruit>();
fruitBasket.add(new Apple("Granny Smith"));
fruitBasket.add(new Banana("Chiquita"));
fruitBasket.add(new Apple("Golden Delicious"));
int priceOfBasket = 0;
for(Fruit pieceOfFruit:fruitBasket) {
priceOfBasket += pieceOfFruit.getPrice();
Set<Apple> appleScale = new HashSet<Apple>();
appleScale.add(new Apple("Granny Smith"));
appleScale.add(new Apple("Golden Delicious"));
appleScale.add(new Banana("Chiquita")); // ERROR

How to Bind a Combo Box so that it retrieves and display content corresponding to the Id in a link table and populates itself with the data in the main table?

I am developing a desktop application in Wpf using MVVM and Entity Frameworks. I have the following tables:
1. Party (PartyId, Name)
2. Case (CaseId, CaseNo)
3. Petitioner (CaseId, PartyId) ............. Link Table
I am completely new to .Net and to begin with I download Microsoft's sample application and
following the pattern I have been successful in creating several tabs. The problem started only when I wanted to implement many-to-many relationship. The sample application has not covered the scenario where there can be a any-to-many relationship. However
with the help of MSDN forum I came to know about a link table and managed to solve entity framework issues pertaining to many-to-many relationship. Here is the screenshot of my application to show you what I have achieved so far.
And now the problem I want the forum to address is how to bind a combo box so that it retrieves Party.Name for the corresponding PartyId in the Link Table and also I want to populate it with Party.Name so that
users can choose one from the dropdown list to add or edit the petitioner.

Hello Barry,
Thanks a lot for responding to my query. As I am completely new to .Net and following the pattern of Microsoft's Employee Tracker sample it seems difficult to clearly understand the concept and implement it in a scenario which is different than what is in
the sample available at the link you supplied.
To get the idea of the thing here is my code behind of a view vBoxPetitioner:
<UserControl x:Class="CCIS.View.Case.vBoxPetitioner"

</HeaderedContentControl.Header>
<ListBox BorderThickness="0" SelectedItem="{Binding Path=CurrentPetitioner, Mode=TwoWay}" ItemsSource="{Binding Path=tblParties}" />
</HeaderedContentControl>
</Grid>
</UserControl>
This part is working fine as it loads another view that is vPetioner perfectly in the manner I want it to be.
Here is the code of vmPetitioner, a ViewModel:
Imports Microsoft.VisualBasic
Imports System.Collections.ObjectModel
Imports System
Imports CCIS.Model.Party
Namespace CCIS.ViewModel.Case
''' <summary>
''' ViewModel of an individual Email

Private petitioner As tblParty
''' <summary>
''' Initializes a new instance of the EmailViewModel class.
''' </summary>
''' <param name="detail">The underlying Email this ViewModel is to be based on</param>
Public Sub New(ByVal detail As tblParty)
If detail Is Nothing Then
Throw New ArgumentNullException("detail")
End If
Me.petitioner = detail
End Sub
''' <summary>
''' Gets the underlying Email this ViewModel is based on
''' </summary>
Public Overrides ReadOnly Property Model() As tblParty
Get
Return Me.petitioner
End Get
End Property
''' <summary>
''' Gets or sets the actual email address
''' </summary>
Public Property fldPartyId() As String
Get
Return Me.petitioner.fldPartyId
End Get
Set(ByVal value As String)
Me.petitioner.fldPartyId = value
Me.OnPropertyChanged("fldPartyId")
End Set
End Property
End Class
End Namespace
And below is the ViewMode vmParty which vmPetitioner Inherits:
Imports Microsoft.VisualBasic
Imports System
Imports System.Collections.Generic
Imports CCIS.Model.Case
Imports CCIS.Model.Party
Imports CCIS.ViewModel.Helpers
Namespace CCIS.ViewModel.Case

''' <summary>

''' </summary>
Public Property fldName() As String
Get
Return Me.Model.fldName
End Get
Set(ByVal value As String)
Me.Model.fldName = value
Me.OnPropertyChanged("fldName")
End Set
End Property
''' <summary>
''' Constructs a view model to represent the supplied ContactDetail
''' </summary>
''' <param name="detail">The detail to build a ViewModel for</param>
''' <returns>The constructed ViewModel, null if one can't be built</returns>
Public Shared Function BuildViewModel(ByVal detail As tblParty) As vmParty
If detail Is Nothing Then
Throw New ArgumentNullException("detail")
End If
Dim e As tblParty = TryCast(detail, tblParty)
If e IsNot Nothing Then
Return New vmPetitioner(e)
End If
Return Nothing
End Function
End Class
End Namespace
And final the code behind of the view vPetitioner:
<UserControl x:Class="CCIS.View.Case.vPetitioner"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:vm="clr-namespace:CCIS.ViewModel.Case"
mc:Ignorable="d"
Width="300">
<UserControl.Resources>
<ResourceDictionary Source=".\CompactFormStyles.xaml" />
</UserControl.Resources>
<Grid>
<Border Style="{StaticResource DetailBorder}">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="Petitioner:" />
<ComboBox Grid.Column="1" Width="240" SelectedValuePath="." SelectedItem="{Binding Path=tblParty}" ItemsSource="{Binding Path=PetitionerLookup}" DisplayMemberPath="fldName" />
</Grid>
</Border>
</Grid>
</UserControl>
The problem, presumably, seems to be is that the binding path "PetitionerLookup" of the ItemSource of the Combo box in the view vPetitioner exists in a different ViewModel vmCase which serves as an ObservableCollection for MainViewModel. Therefore,
what I need to Know is how to route the binding path if it exists in a different ViewModel?
Sir, I look forward to your early reply bringing a workable solution to the problem I face.
Warm Regards,

How to bind a UI element to the context

Hi Experts,
           I have a problem binding UI element to the context. In my code i have to create TabStrips dynamically and under this tabstrip number of UI elements would be there. For this i have a code like this..
IWDTransparentContainer theActionContainer =(IWDTransparentContainer)view.getElement("RootUIElementContainer");
     IWDTabStrip ts = (IWDTabStrip) view.createElement(IWDTabStrip.class,"TabStrip");
          IWDTab tab1 = (IWDTab) view.createElement(IWDTab.class,"Tab1");
          IWDInputField in = (IWDInputField) view.createElement(IWDInputField.class,"in");
          IWDCaption header1 = (IWDCaption) view.createElement(IWDCaption.class,"Header1");
          header1.setText("Tab1");
          tab1.setContent(in);
          ts.addTab(tab1);
          IWDTab tab2 = (IWDTab) view.createElement(IWDTab.class,"Tab2");
          IWDInputField in2 = (IWDInputField) view.createElement(IWDInputField.class,"in2");
          IWDCaption header2 = (IWDCaption) view.createElement(IWDCaption.class,"Header2");
          header2.setText("Tab2");
          tab2.setHeader(header2);
          ts.addTab(tab2);
          theActionContainer.addChild(ts);
<b>when i run this code it is giving following exceptions..</b>

From these exceptions what i understood is, i need to bind these UI elements to context.
   Can any body tell me how to bind a UI element to the context if I understood the exceptions correct..
Thanks in Advance,
Murthy.

HI,
lets say Ctx is your context attribute,
IWDAttributeInfo attrInfo = wdContext.getNodeInfo.getAttribute("Ctx");
then , as per your code,
IWDInputField in = (IWDInputField) view.createElement(IWDInputField.class,"in");
<b>in.bindValue(attrInfo);</b>
if your contex attribute is child of some other node then do like this,
IWDAttributeInfo attrInfo = wdContext.getNodeInfo.getChildNode("SalesOrder",0)getAttribute("Ctx");
//this is when Ctx is child of node SalesOrder, and we are taking Ctx from its 0th element
then ,
IWDInputField in = (IWDInputField) view.createElement(IWDInputField.class,"in");
<b>in.bindValue(attrInfo);</b>
include this in your code ,
let me know if you face any problem
regards
reward points if it helps

Dynamic binding of items in sap.m.Table using XML views

Dear SAPUI5 guru's,
Let's start by saying I'm an ABAP developer who's exploring SAPUI5, so I'm still a rookie at the time of writing. I challenged myself by developing a simple UI5 app that shows information about my colleagues like name, a pic, address data and their skills. The app uses the sap.m library and most of the views are XML based which I prefer.
The data is stored on an ABAP system and exposed via a gateway service. This service has 2 entities: Employee and Skill. Each employee can have 0..n skills and association/navigation between these 2 entities is set up correctly in the service. The data of this service is fetched from within the app using a sap.ui.model.odata.ODataModel model.
The app uses the splitApp control which shows the list of employees on the left side (master view). If a user taps an employee, the corresponding details of the employee entity are shown on the right (detail view).
Up till here everything is fine but I've been struggling with my latest requirement which is: show the skills of the selected employee in a separate XML view when the user performs an action (for the time being, I just created a button on the detail view to perform the action). After some hours I actually got it working but I doubt if my solution is the right way to go. And that's why I'm asking for your opinion here.
Let's explain how I got things working. First of all I created a new XML view called 'Skills'. The content on this view is currently just a Table with 2 columns:
<core:View xmlns:core="sap.ui.core" xmlns:mvc="sap.ui.core.mvc" xmlns="sap.m"
controllerName="com.pyramid.Skills" xmlns:html="http://www.w3.org/1999/xhtml">
<Page title="Skills"
       showNavButton="true"
       navButtonPress="handleNavButtonPress">
<content>
<Table
   id="skillsTable">
<columns>
<Column>
<Label text="Name"/>
</Column>
<Column>
<Label text="Rating"/>
</Column>
</columns>
</Table>
</content>
</Page>
</core:View>
The button on the Detail view calls function showSkills:
showSkills: function(evt) {
var context = evt.getSource().getBindingContext();
this.nav.to("Skills", context);
var skillsController = this.nav.getView().app.getPage("Skills").getController();
skillsController.updateTableBinding();
Within 'this.nav.to("Skills", context);' I add the Skills view to the splitApp and set its bindingContext to the current binding context (e.g. "EmployeeSet('000001')"). Then I call function updateTableBinding in the controller of the Skills view which dynamically binds the items in the table based on the selected employee. So, when the ID of the selected employee is '000001', the path of the table's item binding should be "/EmployeeSet('000001')/Skills"
updateTableBinding: function(){
var oTemplate = new sap.m.ColumnListItem(
{cells: [
          new sap.m.Text({text : "{Name}"}),
          new sap.m.Text({text : "{Rating}"})
var oView = this.getView();
var oTable = oView.byId("skillsTable");
var oContext = oView.getBindingContext();
var path = oContext.sPath + "/Skills";
oTable.bindItems(path, oTemplate);
Allthough it works fine, this is where I have my first doubt. Is this the correct way to bind the items? I tried to change the context that is passed to this.nav.to and wanted it to 'drill-down' one level, from Employee to Skills, but I couldn't manage to do that.
I also tried to bind using the items aggregation of the table within the XML declaration (<Table id="skillsTable" items="{/EmployeeSet('000001')/Skills}">). This works fine if I hard-code the employee ID but off course this ID needs to be dynamic.
Any better suggestions?
The second doubt is about the template parameter passed to the bindItems method. This template is declared in the controller via javascript. But I'm using XML views! So why should I declare any content in javascript?? I tried to declare the template in the XML view itself by adding an items tag with a ColumnListItem that has an ID:
                <items>
                    <ColumnListItem
                    id="defaultItem">
                    <cells>
                        <Text text="{Name}"/>
                        </cells>
                        <cells>
                        <Text text="{Rating}"/>
                        </cells>
                    </ColumnListItem>
                </items>
Then, in the updateTableBinding function, I fetched this control (by ID), and passed it as the template parameter to the bindItems method. In this case the table shows a few lines but they don't contain any data and their height is only like 1 mm! Does anyone know where this strange behaviour comes from or what I'm doing wrong?
I hope I explained my doubts clearly enough. If not, let me know which additional info is required.
Looking forward to your opinions/suggestions,
Rudy Clement.

Hi everybody,
I found this post by searching for a dynamic binding for well acutally not the same situation but it's similar to it. I'm trying to do the following. I'm having a list where you can create an order. On the bottom of the page you'll find a button with which you're able to create another order. All the fields are set to the same data binding ... so the problem is if you've filled in the values for the first order and you'll press the button you'll get the same values in the second order. Is it possible to generate a dynamic binding?
I'm going to post you a short code of what I'm meaning:
<Input type="Text" value="{path: 'MyModel>/Order/0/Field1'}" id="field1">
     <layoutData>
                <l:GridData span="L11 M7 S3"></l:GridData>
           </layoutData>
</Input>
As you can see I need to set the point of "0" to a dynamic number. Is there any possibility to reach this???
Hope you can help
Greetings

How to bind "Image Field" object on a database

Hi to all
I inserted into a dynamic PDF (Livecycle ES3 trial) an image field, but I don't understand how I can to bind a JPG into a database.
In (F5) preview... I'm able to open a image file on filesystem and visualize it on PDF form... but then? How to bind on database?
In my several tentatives I'm using a MS Access 2010 database table, where I defined a OLE object... but doesn't work.
Thank you at all.

Dynamically Binding to Dynamically Create View

I tried to copy the code of Dynamically Binding to Dynamically Create View object but something is wrong because when I am debbuging it doesnt work after the sentence vo.executeQuery();
I suspect that the reason could be how I created the view..
Your code is running well but not mine.
It shows this error
JBO-29000: Unexpected exception caught: java.lang.NullPointerException, msg=null
null
I dont know why because the code is the same.
How did you create the objet view ?
Could you help me?

I'd recommend checking out this article on Debugging ADF Applications:
http://www.oracle.com/technology/products/jdev/tips/muench/debugger/index.html
and then reporting here the full stack trace using the tips described in that article.

Dynamic binding of partner links with different payloads

In dynamic binding of partner links, can we have different payloads for different
webservices ?

Hi Marc,
I have one question regarding the use of <xsd:anyType>, Before that let me clear our requirement. We are trying to create a BPEL flow (Consumer) which has the ability to call other webservices (Producers) dynamically. There can be a number of Producer Webservices performing the same task. The end user should be able to add new Producer Webservices and remove already existing ones. We achieved this using EndPointReference (http://www.oracle.com/technology/pub/articles/bpel_cookbook/carey.html) but the problem with this approach is that all the producer webservices have to work on a common schema. We want to support webservices working on different payloads.
My understanding is that when we map the XML document to xsd:anyType in the service's WSDL file, the producer web service need to have an implementation of this type in for of a java class. Is this correct ? Or can we provide the java implementation in our code itself? Can you please point me to some detail documentation on xsd:anyType?
Thanks

How to bind Links Detail Button to an object?

Hi,
As per the WebCenter Dev Guide, we can create link from "Any object to which you bind the custom JSF components, such as the Links Detail Button".
How to bind Link Details Button to an object?
TIA

Each object has a unique id associated to it. One can retrieve that id string from an object by calling the toString() method, as long as this method hasn't been overridden from its default behavior.and if it has System has a method to help you.
But it is not quite a unique id. It might be, but a different JVM could implemented it as "return 1" and it would still technically satisfy the contract.
As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the JavaTM programming language.)

How dynamically get an agent f a level-by-level workflow after PO changed

Hi all:
     I'm trying to create a level-by-level workflow after PO changed, but how dynamically get an agent and how assign it to
task dynamically?
    Thank you very much!!!

Hi Sony,
There are diffrent ways to get agent level by level....it depends from where you are getting the agents.
1>Suppose you have 2 level PO worklfow and my agents are stored in some custom table:-
    level1 -- agent1
    level2 --agent2
2> You can create two attributes in your BO i;e zgent1& zagent2.
3> Inside the attributes zagent1 u will get the actual agents from custom table by putting code
   i.e select agent1 into zagent1 from zcus_tab where level = 1.
4> Inside the attributes zagent1 u will get the actual agents from custom table by putting code
   i.e select agent1 into zagent1 from zcus_tab where level = 2.
5> Now generate the BO...and test it ..u will se the user id of agents in the attributes populated.
6> Now bind these both attributes to workflow container.
7> Use attribute ZAGENT1 for level 1 approval task in worlfow.
8> Use attribute ZAGENT2 for level 2 approval task in worlfow.
The values will comes dynamically from custom table...which u will maintain.
