Initially, Web Applications was very simple ( developed in the 1990s )
Application Tier Contains a Web Server, which maintains the components such as Servlet, JSP
The component is a piece of code, which implements the well-defined interface.
A Single Component is not an Application.
An Application consists of many no. of components working together.
The component handles the complete task, such as Business Logic, Database Transactions Logic, and Presentation Logic.
1. Only One Application developer has to develop the complete component
2. Application developer has to concentrate on Business Logic, Database Transactions Logic as well as Presentation Logic.
3. Application Developer Must have the Multiple Skills
4. Development Time is more
5. Lot of confusion with Business Logic, Database Transactions Logic, and Presentation Logic since they are being developed as single components.
To overcome the above disadvantages MVC1 Architecture was introduced
M ⇒ Model V ⇒ View C ⇒ Controller
Model: Model Represents data object. Model is what is being manipulated and presented to the user
View: Serves as Screen representation of Model. It is the object that presents the current state of the data objects.
Controller: Defines the way the user interface reacts to the user’s input. The Controller component is the object that manipulates the model or data object.
In MVC1 Architecture
→ Servlet / JSP acts as View as well as Controller.
→ Java Bean acts as a Model Component.
To overcome the above disadvantages MVC2 Architecture has been introduced
Struts Framework follows the MVC2 Architecture
→ Servlet acts as Controller
→ JSP acts as View
→ Java Bean acts as Model
It is a java Servlet called Action Servlet. It receives a request from the web client and stores data into the Java Bean called as Form Bean (Model) and receives a response (success/fail) from the Form Bean. Based on the response from Form Bean, Action Servlet decides, which page (view) to be presented to the client.
It is Java Bean called Form Bean. It will receive the client data through the Controller and performs the data validations or database transactions such as DML and DQL operations. After performing database transactions it provides the data for the view.
It is a JSP. It populates the data from the Form Bean ( Model ) and Present to the user.
The architecture of Oracle Application FrameWork is similar to the Struts FrameWork but some difference is there.
AM ⇒ Application Module VO ⇒ View Object EO ⇒ Entity Object
→ It is a Java Class.
→ OAControllerImpl is a parent of all Controller Classes.
→ The controller performs database transactions through the Application Module interface.
→ It will get the data through the Application Module and Push into the View.
→ It is JSP with GUI Components.
→ It populates data into its GUI components from VO.
→ It is to interact with the Database through the BC4J Components.
→ It is a combination of Application Module, View Object, and Entity Object.

1. Get the JDeveloper software ( ZIP File: p4141787_11i_GENERIC.zip )
2. Copy into required drive ( folder ) / ( C:)
Eg: C: JDEV ( create JDEV ( name can be anyone ) folder in C-drive
3. Extract the ZIP file name p4141787_11i_GENERIC.zip )
Right-click ⇒ WinZip ⇒ ExtractToHere
After extracting it generates the following
4. Take the shortcut of C:JDEVjdevbinjdevbin jdevW.exe to desktop
5. Copy the dbc file form Oracle Apps Server to JDeveloper
Source Oracle Apps path: D:oraclevisapplfnd11.5.0secureVIS_appsvis.dbc
JDevelopre Path: C:JDEVjdevhomejdevdbc_filessecure
6. Set the Environment variables of O/S
My Computer → Advanced → Environment Variables → New →
Variable Name: JDEV_USER_HOME
Variable Value : C:JDEVjdevhomejdev
OK → OK → OK
1. go to connection à Right Click à New database connection à Next à
Connection Name: test ( as desired )
Connection Type : Oracle ( JDBC )
2. User Name: apps
3. Driver: thin
Host Name: localhost ( if the database is on the local system, else URL of DB server )
JDBC Port: 1521
For details see the vis.dbc located in the folder :
4. Test Connection
Result : success
The packages, which are used in the OA Frame Work Applications.
There are six package used in the OA Frame Work Applications.
1) <3rd party identifier > .oracle.apps... .webui
2) <3rd party identifier > .oracle.apps... lov.webui
3) <3rd party identifier > .oracle.apps... .server
4) <3rd party identifier > .oracle.apps... lov.server
5) <3rd party identifier > .oracle.apps... poplist.server
6) <3rd party identifier > .oracle.apps... Schema.server
Steps to Develop the Application
1. Create the workspace
2. Create the project
3. Create the package
4. Create the application module
5. Create the page
6. Set the properties of the page
1) Creation of Work Space
WorkSpace → Right-Click → New OA workspace
Directory Name: C:JDEVjdevbinjdevmyprojects
File Name: xxclinet.jws ( jws → Java Work Space )
Select Add a New OA Project
2) Creation of a project
Directory Name: C:JDEVjdevbinjdevmyprojects
Project name: First.jpr
Package Name: first.oracle.apps.po.hello.WebUI
Syntax: for Pack name
<3rd party identifier > .oracle.apps....webui
In the above
<3rd party identifier > → mycompany
 → it is an optional ( as desired )
Use Responsibility for design time
Supply the name of connection: test
Here New → to create a new connection
Edit → to change the name of the connection
DBC File Name : C:JDEVjdevhomejdevdbc_filessecurevis.dbc
User name: operations ( front end-user )
Application short Name: PO
Responsibility key: PURCHASING_OPERATIONS
Next – Finish
3) Create a package
Right click on .jpr file → New Business Component Package → Next
Package Name : first.oracle.apps.po.hello.server
( Select Entity object mapped to database schema objects )
Connection Name: test
SQL Flavour: oracle
Type Map: oracle
User name: apps
Next → finish
Note: it generates test Connection
4) Create Application Module
Right Click on package → New Application Module → Next →
Name : TestAM
Package : first.oracle.apps.po.hello.server
Next → Next → Next → Next → finish
Note: It generates the following files
5) Creation of a Page
Right Click on .jpr file → New → Web Tier → OA Components → Page → OK
Package : first.oracle.apps.po.hello.WebUI
Note: It generates the file called: HelloPG.xml
6) Set the Properties of the page
Select the page → Structure →
AM Definition: click on the list box and select the AM ( TestAM )
Window Title: Hello Page
Title: Hello This is my First Page
( at least one of the above two 1) Window Title 2) Title is required )
7) Build the Application
Right-click on .jpr → Re-build
8) Run the Page Go to XML → Right Click → Run Page

Adding Items to region
Before creating items take a header region ( as desired )
Naming Convention for Region :
Name Starts with purpose
Name ends with RN
Right Click on Region1(RootRN)/ (HeaderRN) → item
Id : UserId
Item Style : messageTextInput
Prompt : User Name
Data Type : VARCHAR2 ( As desired )
Comments : Created for Login User Id
Required : Yes ( Yes → Mandatory field, No → Optional )
Read only : True ( to make it as read only filed, we can not edit the filed )
False → we can edit the filed.
( use for Id generating automatically , used with database sequence )
Disable : true ( to avoid the cursor focus into the text filed )
Maximum Length : the maximum that can be entered into the text filed.
Initial Value : default value
Additional Text : text to be displayed when muse over the item.
Rendered : false → to hide the text filed from the user.
CSS Class : setting back ground colors.
Length : Width of the text field, that can be visible to user
Height : 1 ( it will not generate multiple lines )
> 1 to generated the multiple lines automatically
Vertical Alignment : Top/Middle/Bottom ( Prompt alignment )
