How to access unamed components

If I had a frame with 100 text fields which was added to the frame using the following loop. How can I access and identify individual textfields
for (int i=0;i<100;i++)
someframe.add(new JTextField());
}Any help is appreciated

You could do something like the following:
for (int i=0;i<100;i++)
someframe.add(new JTextField(),setName("someUniqueName"));
code]But that would require searching through the list of fields in the container looking for the correct field (not efficient).
I suggest using the array suggestion. Or if you don't want to index them numerically, you could use a hashmap and map then to specific names.

How to access/identify components in JSF Declarative Components?

Hi,
I am beginner on ADF. Trying to build first Declarative Components.
Use Case is as follows -
I have put 2 InputTexts in Declarative Component.
Want to set some value in second InputText (txtAddressLine2) in Validator/ValueChangeListner method of first InputText(txtAddressLine2).
<?xml version='1.0' encoding='windows-1252'?>

</af:componentDef>

</jsp:root>
This is sample I am working on.
I am trying following approaches in bean of Component itself.
Approach I: This does not give any error, value is not set in txtAddressLine2
this.getTxtAddressLine2().setValue("Some Value");
Approach II: Not able to access txtAddressLine2 using findComponent() method
UIViewRoot uiViewRoot = facesContext.getViewRoot();
RichInputText inputText;
inputText = null;
if (uiViewRoot.findComponent("txtAddressLine2") != null) {
System.out.println("Found ");
inputText = (RichInputText)uiViewRoot.findComponent("txtAddressLine2");
inputText.setValue("my value");
} else {
System.out.println("Not Found "); //Always not found
Can anybody tell me correct way to access components and set their values inside Declarative Components itself?

Thanks buddies....its resolved!
This is how I have done it -
Components have these 2 Input Texts :
<af:inputText label="Label 1" id="txt1" autoSubmit="true" immediate="true"
binding="#{DC2.txt1}" validator="#{DC2.txt1_validator}"/>
<af:inputText label="Label 2" binding="#{DC2.txt2}" id="txt2"
immediate="true" autoSubmit="true" partialTriggers="txt1"/>
Code in Component Bean setting value is as follows:
RichInputText txt22;
txt22 = getTxt2();
txt22.setSubmittedValue("Some Value");

How to Access MXML components from ActionScript class

Hi ,
I am having a Application Conataner , in which i am having a Form Container with some Label in it .
This is some thing similar to this as shown :
<Mx:Application>
<Mx:Form>
<Mx:Label text="Hello world"/>
</Mx:Form>
</Mx:Application>
Can any body please let me know how can i access this Form's Label , from an ActionScript class .
catch(error:*)
// Here i want to access these Objects and set data to that Label .
Basically My requirement is that iinside the catch block of my ActionScript class , i want to set some text to the Label , Please
let me know if this is possible or not also ??
Waiting for your Replies .

Hi these both are not same these refer to different one...
Well let me explain...
Application.application.myCustomComp.myLabel.text = "sometext"; sets the label "myLabel" which is present inside your customcomponent(which is in main application).
Application.application.myLabel.text = "sometext"; sets the label "myLabel" which is present directly inside your main application.
<?xml version="1.0"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:Label id="myLabel" text=""/> // So inorder to set the label(myLabel) present here you will use directly the 2nd line of code.
<mx:CustomComp id="myCustomComp" /> // So inorder to set the label(myLabel) present inside this component you use 1st line of code.
</mx:Application>
Hope now its clear.
If this post answers your question or helps, please kindly mark it as such.
Thanks,

How to access graphic components from classes?

Hi,
I am creating a Flex application. In my Main.mxml, I add
different UI elements, such as panels. I also have a few
actionscript files. Everything is in the same folder. So my
question is : how can I access a panel created in Main.mxml from an
actionscript class ? By accessing the panel, I mean things like
change its properties, etc. Is it possible to access those in a
'Flash-like' way, using something like _root.myPanel, or is it only
possible through passing parameters?

Well...it pains me to see someone obviously new to programming struggle here...so I'll take this one on:
Here is the BAD way to do it...but it is basically what you are looking for...to learn GOOD ways to do this, please invest in some programming books and learn about encapsulation, MVC, and other programming/architectural styles...anyways...here is the BAD, but easy way:
In your SGui class, right after the constructor you have to "declare" your object reference as a class member, so edit your file to make it say:
public class SGui {
public JButton addStickButton;Then, edit the line in SGui that says:
final JButton addStickButton = new JButton();so that it just says:
addStickButton = new JButton();Then, in your Soft class, you can access it just the way you wanted to in your comment:
gui.addStickButton.setEnabled(false);Other Java programmers reading this thread will probably shoot me for showing you how to do it this way, because it violates principles of encapsulation...but go ahead and use it so you can move forward...but study a little more online or in books to get the hang of it :)

How to access UI components in event handler

Hi
How can I access all or a particular UI component's object in my event handler of a event which is not caused by that UI component which is being accessed.

You need variable resolution:
FacesContext context = FacesContext.getCurrentInstance();
Application application = context.getApplication();
WaferMap waferMap = (WaferMap)application.getVariableResolver().resolveVariable(context, "waferMap");or you can ask the event for ones near by
    //action from an h:commandLink
     public void seeMore(javax.faces.event.ActionEvent event)
       System.out.println("action: seeMore "+((HtmlCommandLink)event.getSource()).getAttributes());
        java.util.List map=((HtmlCommandLink)event.getSource()).getChildren();
        Iterator i=map.iterator();
        System.out.println("action: seeMore ");
        while(i.hasNext())
            Object obj=i.next();
            if(obj instanceof UIParameter)
                UIParameter param=(UIParameter)obj;
                System.out.println("\t seeMore "+param.getValue()+" ");
    }

Movie Themes: How to access individual components

After playing around with PRE7's "Themes" functions (which I gather is also called "instant movie"?), and unbundling the instant movie into individual, editable elements, I was wondering if there's a way to access the sound effects and graphics used by instant movie.
For example, I used the "Extreme Sports" theme. After unbundling the instant movie, some of the video transitions I recognized from the standard Effects or Transisions folders of the Edit panel.
But other video effects (e.g. the "opening/closing credit" moving graphic) and sound effects (e.g. "explosion" or "glass shattering") I don't remember seeing anywhere.
Am I missing something, or are some of the video/audio effects that are only available by applying then unbundling the instant movie?
Thanks!!
Ed

Not yet.
I first wanted to make sure there wasn't some way in PRE to do it, like a "sound effects" tab or something I wasn't seeing.
If it turns out that there isn't, then my next stop was certainly to start poking around to see if I could import them as distinct items.
If that's the case, I may just create my own "effects" folder and import everything I can find. Kind of create my own effects tab, in effect.

How to list/access swing components?

hi all,
Can anyone give me a clue, how can I access or simply list swing components I have on a frame, long after I created them. E.g. I'd like to change their setEnabled() attribute at a later time, not at creation time, but I don't know how to access them.
Does Swing/AWT/JFC provides a component hierarchy? can someone share some code on this issue?
Thanks for any help.
Thomas

I guess, you are saying the use of getComponent(int n)?
Since I'm a beginner in Swing see my short code below:
import java.awt.BorderLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JMenu;
import javax.swing.JMenuBar;
import javax.swing.JMenuItem;
import javax.swing.JTextArea;
public class EasyFrame {
    public EasyFrame() {
        super();
        startHere();
    public void startHere() {
        JFrame frame = new JFrame("SwingApplication");
        JButton button = new JButton("click here");
        JTextArea area = new JTextArea();
        frame.setSize(300, 200);
        frame.getContentPane().setLayout(new BorderLayout());
        frame.getContentPane().add(area, BorderLayout.CENTER);
        frame.getContentPane().add(button, BorderLayout.SOUTH);
        area.setText("Hello World");
        JMenuBar menuBar = new JMenuBar();
        JMenu menu = new JMenu("A Menu");
        menuBar.add(menu);
        JMenuItem menuItem = new JMenuItem("A text item");
        menu.add(menuItem);
        menu.addSeparator();
        menuItem = new JMenuItem("hello");
        menu.add(menuItem);
        JMenu subMenu = new JMenu("submenu");
        menuItem = new JMenuItem("sub1");
        subMenu.add(menuItem);
        menuItem = new JMenuItem("sub2");
        subMenu.add(menuItem);
        menu.add(subMenu);
        frame.getContentPane().add(menuBar, BorderLayout.NORTH);
        frame.show();
     public static void main(String[] args) {
     EasyFrame ef = new EasyFrame();
}If I make a System.out.println(frame.getContentPane().getComponentCount());I get 3. But I should dig deeper (with getComponent(2)) to access JMenuBar. But this way I receive a AWT Component / not a JMenuBar Swing component to get its JMenu / and its JMenuItems. And I cannot make it cast to JMenuBar since this walk-through routine should be a universal while(isThereMoreCompenent){} procedure, I don't know when to cast to what (JMenu, JMenuItem, Button and so on).
My problem is that how can I access the JMenuItems one by one, and change e.g. the setEnabled attribute of the "hello" menu?
I hope you can make it clear to me.
Please help if so.

How to access tables/views of an external database provider..

After much trouble I finally managed to setup a second Database Provider that doesn't display the "0 out of 0 connections are good" error by filling in the "Configuration Class" field with "intradoc.server.DbProviderConfig".
But now the problem is actually accessing the tables/views in my newly configured external database provider...
In the Configuration Manager applet when I try to add a new Table or View it only lists the tables contained in the schema of the SystemDatabase database provider (the original one), I've tried running Queries via components trying stuff like SELECT * FROM provider_name.table_name and other similar but obviously it doesn't work...
So... with that said, I just want to know how I access tables or views in my "supposedly" well conected (15 out of 15 connections are good, no errors on the Test Query) Oracle external Database Provider - After searching I was unable to find any information regading any post-provider-setup actions in the Content Server documentation - Does anyone know how to do this?
On a side note, if the database is SQLServer instead of Oracle, with the same configuration and apparently no errors on the database side (other clients access it well) the Query Test of the new database provider returns the following error:
"The provider 'TestSqlSrv' is in error. Unable to create database connection for JDBC:ODBC:SqlSrv. Unable to create result set for query 'select * from dummy'. Invalid Fetch Size Unable to create result set for query 'select * from dummy'. Invalid Fetch Size java.sql.SQLException: Invalid Fetch Size".But I won't even go there yet.... for now I would settle with just knowing how to reference information in the Oracle external database provider...

How to access dataprovider through jsp syntax

I am creating an image gallery but here's my issue...
I have a database table that contains links to images on my file system. I created a dataprovider for this database table on my page so the dataprovider now returns all the image links.
Now what I need to do is create a row of thumbnails so I add a scriptlet in my jsp code where I want the thumbnail to appear. This scriptlet loops through the dataprovider and for each row it will create a standard html image tag populating the src attribute with the link from the dataprovider.
I figure creating dynamic html img tags is much easier than creating dynamic image components in the backing bean. Doing the former allows me to output the row of thumbnails exactly where I want them on the page (ie where i put my scriptlet code) and is easier to manage.
The problem is i don't know how to access the dataprovider through jsp tags and syntax. I'm sure there must be a way, can anyone help?
Thanks.

I've done this sometimes using scriplets:
<%
request.setAttribute("SOME_CONST", Constants.SOME_CONST);
%>
<c:out value="${SOME_CONST}" />But I would also be interested if anyone knows a way without those ugly scriplet..

How to access BPM 11g payload or process varibles in ADF task flow

I am trying to view/edit data in a UI tied to a database using a foreign key, requestId. The foreign key comes from a BPM process where it is passed into the task flow, from a human task. The foreign key comes from process variables or payload values. I know I can simply load the payload in BPM with data from the tables, but I'm looking for a better solution to leverage ADF Business components to view and edit the data directly in the UI.
The BPM process uses a web service to kick off the process. The web services takes a primary key as a parameter to reference a column in the database table. The database is pre-populated with content and a primary key reference. The first activity is a user activity. I want the task flow behind the user activity to accept this primary key and use it to locate the desired row in the database so views associated with database bounded ADF Business Components can work to present the data in the UI.
I've tried two approaches to the problem. The first uses the operation setCurrentRowWithKeyValue. The other modifies the SQL where clause, used by the ADFbc Iterator, to only return a row for the given requestId. Both approaches fail to work because I don't know how to access the BPM payload or data variables coming into the task flow. Here's the snipet of code I used to try to set the row using setCurrentRowWithKey value:
public String setRequestId() {
FacesContext context = FacesContext.getCurrentInstance();
Object requestObj = context.getApplication().evaluateExpressionGet(
context, "#{bindings.RequestId.inputValue}", Number.class);
if (requestObj== null)
return null;
Number requestId;
requestId = (Number)requestObj;
DCIteratorBinding itr = (DCIteratorBinding)
getBindings().get ("PatfRequestHdrView1");
itr.setCurrentRowWithKeyValue(requestId.toString() );
return null;
I haven't gotten very far with the second approach, modified SQL where clause, since I don't know Groovy. I think I need something like:
adf.object.viewObj.RequestId. But there isn't a viewObject associated with BPM data, so I'm sure this particular expression won't work.
Any help you can give me is very appreciated.
Regards,
Mark

The first thing I want the task flow to do is display a page with a form showing the values from the database. This is why I tried to call the method first. If I add the setCurrentRowWithKey to the form as a button, I can get the form to load the data, but it's a two step process, requiring the user to click a button. The method approach throws the following exceptioin

How to access the Microsoft Dynamics database tables for creating a DW

Hi all,
I m trying to build a POC for the manufacturing industry (Dairy Industry).
Hence I'm trying to install Microsoft Dynamics and access the tables available its OLTP and create a warehouse.
Please let me know how we access the database tables of Microsoft Dynamics to do etl (using any etl tool).
Then i would be creating reports and dashboard using OBIEE 11G.
I thought of getting help before installing microsoft dynamics so that i can install the necessary components to achieve the same.
Please let me know the necessary things i would need to do.
Thanks
Jaan

Hi,
I think this can be possible with microsoft ssis etl tool.
Thanks,

OOABAP-How to access the protected methos from a class

How to access the protected methos from a class..There is a built in class..For tht class i have created a object..
Built in class name : CL_GUI_TEXTEDIT
method : LIMIT_TEXT.
How to access this..help me with code

hi,
If inheritance is used properly, it provides a significantly better structure, as common components only
need to be stored once centrally (in the superclass) and are then automatically available to subclasses.
Subclasses also profit immediately from changes (although the changes can also render them invalid!).
Inheritance provides very strong links between the superclass and the subclass. The subclass must
possess detailed knowledge of the implementation of the superclass, particularly for redefinition, but also in
order to use inherited components.
Even if, technically, the superclass does not know its subclasses, the
subclass often makes additional requirements of the superclass, for example, because a subclass needs
certain protected components or because implementation details in the superclass need to be changed in
the subclass in order to redefine methods.
The basic reason is that the developer of a (super)class cannot
normally predict all the requirements that subclasses will later need to make of the superclass.
Inheritance provides an extension of the visibility concept: there are protected components. The visibility of
these components lies between that of the public components (visible to all users, all subclasses, and the class itself), and private (visible only to the class itself). Protected components are visible to and can be used by all subclasses and the class itself.
Subclasses cannot access the private components particularly attributes) of the superclass. Private
components are genuinely private. This is particularly important if a (super)class needs to make local
enhancements to handle errors: it can use private components to do this without knowing or invalidating
subclasses.
Create your class inse24 and inherit this CL_GUI_TEXTEDIT
class in yours. You can then access the protected methods.
Hope this is helpful, <REMOVED BY MODERATOR>

How to access Spectrasonics plug-in?

I'm brand new to Logic. I'm having trouble accessing a Spectrasonics Omnisphere plug-in that I installed. I checked the Library/Audio/Plug-ins/Components folder and I see a file 'omnisphere.component' yet when I'm in Logic I'm confused as to what to do. I click an insert box in a channel strip - select plug-in's - but there is only some apple effects to choose from.
Message was edited by: pianoman1976

I just bought Spectrasonics Omnisphere for my iMac. I am using the computer's default audio settings for now. I am using M-Audio KeyRig 49 for my MIDI keyboard controller. I am new to all this. I tried to use Garage Band (iLife 08) to access the plug in. I cannot. I installed Logic Express 7 to use as a "host sequencer". Since I am new to this, I queried Spectrasonics. They said i had to have a "host sequencer" to use Omnisphere. It cannot be used "on it's own." I cannot, or haven't found out how to access the Omnisphere plug in. Any help here would be appreciated as I am getting very frustrated.
