Add Custom Flash Chat in Oracle ADF Application

In this tutorial i am going to show that how can you add a custom flash chat in your ADF application, and use it to chat with friends.
this is very much simple, as no code required to do this.

Go to http://www.everywherechat.com/ , this site provides free custom flash chat rooms, get html code of your custom chat from here
Create an html page using that code

<html>
<body>
<!-- Begin Everywherechat Room Code -->
    
      <br />
     <script src="http://www.everywherechat.com/e.php?defaultRoom=Lobby&roomList=true&fontSize=12&width=600&height=500&theme=night"></script> 

<!-- End Everywherechat Room Code --> 
</body>
</html>

Now create a Fusion Web Application and create a page in it, call this HTML page in an inlineFrame (af:inlineFrame)

<?xml version='1.0' encoding='UTF-8'?>
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.1" xmlns:af="http://xmlns.oracle.com/adf/faces/rich">
  <af:panelGroupLayout id="pgl1">
    <af:inlineFrame id="if1" source="/chat.html" inlineStyle="height:700px;width:700px;"/>
  </af:panelGroupLayout>
</jsp:root>

Now Run your application and see your flash chat room is ready - Happy Coding

Generate Barcode Image in Oracle ADF using OnBarcode API

In this tutorial we will learn how to generate Barcode Image for any Number(Barcode) in ADF using OnBarcode API, this API provides barcode SDK(Software Development Kit) to generate Barcode. This is paid.
You can get it from http://www.onbarcode.com/ , click on Download to get barcode SDK.

Now create a fusion web application and add barcode.jar to project libraries, you will get this JAR , when you download SDK
Good thing about this API is that it is very simple to use, not much code required to generate a simple barcode image
You can generate multiple type of Barcode as Code 39, Code 128, EAN-8, EAN-13, UPC-A, UPC-E
Suppose i have to generate a Code128 type of Barcode for any barcode number, so for this write this simple code and you are done

Code128 barcode = new Code128();

barcode.setData("122322311");
barcode.drawBarcode();

Download sample application that integrates this API with Oracle ADF Download Sample ADF Application
Unzip and Run this application
I have used a servlet in order to show image on page fragment

Set and Get Value from Taskflow parameter (pageFlowScope variable) from Managed Bean- ADF

Hello All

This post is about getting and setting value in taskFlow parameter using Java Code so for that we have created a application with bounded taskFlow

Let's see how to do this -

We have bounded taskflow having Input Parameter defined in it named GLBL_PARAM_TEST

and we have to set its value from managed bean.
this is very simple -see how to do that

Get pageFlowScope Map and put parameter 's value in it

        Map paramMap = RequestContext.getCurrentInstance().getPageFlowScope();
        paramMap.put("GLBL_PARAM_TEST", "Ashish");

And get Value from taskFlow parameter in managed bean

    public String resolvEl(String data){
               FacesContext fc = FacesContext.getCurrentInstance();
               Application app = fc.getApplication();
               ExpressionFactory elFactory = app.getExpressionFactory();
               ELContext elContext = fc.getELContext();
               ValueExpression valueExp = elFactory.createValueExpression(elContext, data, Object.class);
               String Message=valueExp.getValue(elContext).toString();
               return Message;
             }


String param=resolvEl("#{pageFlowScope.GLBL_PARAM_TEST}");
