What is OAF?

It is a Kind Of Platform to Design the web based Application

In Generally We have Three Applications Available in the Market

Form Based or Desktop ApplicationsWeb Based Applications

Mobile Kind Of Applications

What is the Diff. Between Form Based And Web Based Applications

Form Based Web Based

These Applications not worked under the Network like LAN,WAN independently.

These Applications work Under Networklike LAN,WAN

To Publish These Applications in theNetwork Should Be Required

JDEVELOPER INTRODUCTION

JDeveloper is a freewareIDE supplied by Oracle Corporation. \

It offers features for development in Java, XML, SQL and PL/SQL, HTML, JavaScript, BPELand PHP.

JDeveloper covers the full development lifecycle from design through coding, debugging,

optimization and profiling to deploying.


4/23

With JDeveloper, Oracle has aimed to simplify application development by focusing onproviding a visual and declarative approach to application development in addition to building an

advanced coding-environment.

Oracle JDeveloper integrates with the Oracle Application Development Framework(Oracle

ADF,OAF) - an end-to-end Java EE-based frameworkthat further simplifies applicationdevelopment.

The core IDE exposes an API that other teams in Oracle use to build extensions to JDeveloper.BPEL, Portal, BI and other components of the Oracle platform

[which?]all build their design-time

tools on top of JDeveloper.

Environmental Setups Required To Jdeveloper in the OAF:

Identify and DownLoad The Patch

Extract The Patch Set The DBC File Properly Set Two Environmental Variables

Variable_ name : JDEV_USER_HOME

Variable_ Value : DriveName/FolderName/JdevHome/jdev

Oracle Application Framework

Oracle Applications Framework is also referred to as OA Framework. This is a framework that excels at

creating 3-tier web-based applications that link to an 11i Oracle Applications instance while maintaining

all the security features of that 11i instance. OAF is a model-view-controller technology stack that is fully

oriented towards E-BS application development. The OAF stack is comprised of underlying technologies

like UIX and BC4J that respectively form the core of the view and model layers. It includes Application

Object Library (AOL) that provides common E-BS artifacts such as menus, functions, messages, profiles,

flexfields and attachments, etc.

An important significance of the OA framework model is that it facilitates the customization of existing

out of box i modules as well as allows development of new Self Service Web Application modules. As a

result, the OA Framework provides benefits of productivity, scalability, and customizability. OA

Framework Architecture is based on the J2EE MVC design pattern. The MVC architecture is a

component-based design pattern with clean interfaces between the Model, View, and Controller. The

Model is where the application implements its business logic. The View is where the application

implements its user interface and the Controller is where the application handles user interaction and

directs business flow. Though the OA Framework is J2EE based, it also uses various industry standards

like HTML, XML, Java, JSP, SQL and Web Services.

Note : Any Component in the OAF , In Generally called it as One Java Class

To Control the AOL Standards and performance of the applications by introducing the

specific package Strure.

U Should be Follow Below Package Structures to place java classes in the OAF

Package Structure Syntax

.oracle.apps.po...webui (or) server

Total We can see 6 packages :

.oracle.apps.po... Server

.oracle.apps.po..poplist, server

.oracle.apps.po...lov. server

.oracle.apps.po...schema. server

.oracle.apps.po...webui

.oracle.apps.po...lov.webui


18/23

1

Note : The Package Structure Should be Ends With Either webui or server in the OAF

Which Are the Components inside of webui package Those are Called Client Components

Model-View-Controller Design

y A component-based design with clean interfaces among model, view, and controller objectsy The controller responds to user actions and directs application flowy The view formats and presents data from a model to the usery Model encapsulates data and business logic of the application

View Components in the OAF

Generally The output of Class file is Called it as View in the OAFThe view formats and presents data from a model to the user

View Components are used by the users.View Components in the form of xml

We should be place the view components under only webui packages in the OAF

Examples For View Components in the OAF is

PageRegion

Attribute Sets

Page

Generally we should be ends with the PG,

For Ex:

EmpPG

EmpPG.xml


19/23

.oracle.apps.po..webui

Region

:

Subpart of the pageRN or RGSuppNumberRN.xml

.oracle.apps.po..lov.webui

MODEL in the OAF :

Model is the interface between user and database in the OAFModel encapsulates data and business logic of the applicationIf You Create Any Model Component U can Able To See Two Files In the OAF

Xml and Java Files

View Objects and View LinksEntity Objects and Associations

Application Module

View Objects and View Links

In Generally Select Statement or Query Called it as View Object in the OAF

and It is Java Class,By Using This We Can Retrive The Data From DB.

We Can Build The View Object Class in two Ways

o By Writing Directly Select Statementso Based On the Entity Objects

Naming Convention For ViewObject in the OAF is VO

For Exampleif u Write VO For Emp Data

Naming ConventionEmpVO

Now u can see two filesEmpVO.xml

EmpVOImpl.java


20/23

OAF Gives u Standard that

U Can build the ViewObject Class Below any Of the Package As per the OAF Standards

Except poplist and lov we have to write vos below


For poplist purpose

.oracle.apps.po..poplist, server

For Lov purpose

.oracle.apps.po...lov. server

The Parent Class For All VOs is : OAViewObjctImpl

By Using ViewLinks We Can Join Two VOs Are More Than Two VOs

Note : In The OAF Once U Build The VO , U should be Shuffle to AM As per the OnionStructure

Entity Objects and Associations

In Generally Database Table or View Called it as Entity Object in the OAF and It is

Java Class,By Using This We can perform the DML OperationsLike Insert,update,Delete

Naming Convention For EntityObject in the OAF is EO

For Example if u Write EO For Emp Table

Naming Convention

EmpEO


21/23

2

Now u can see two files

EmpEO.xml

EmpEOImpl.java


U Can build the EntityObject Class Below Package As per the OAF Standards

.oracle.apps.po...schema. server

The Parent Class For All EOs is : OAEntityObjectImpl

By Using Associations We Can Join Two EOs Are More Than Two EOs

Note : In The OAF Once U Build The EO , U should be Shuffle to VO As per the OnionStructure

ApplicationModule

Which is a JavaClass By using We Can able to Implement All the Bussiness Logic andRelated Bc4j Objects .

Naming Convention For ApplicationModulein the OAF is AM

For Example if u Write AM For Emp Bussiness Logic

Naming Convention

EmpAM


22/23

2

Now u can see two files

EmpAM.xmlEmpAM Impl.java


U Can build the ApplicationModule

Class Below Package As per the OAF Standards


.oracle.apps.po...lov server

The Parent Class For All AMs is : OAAppolicationModuleImpl

Note : In The OAF Once U Build The AM is the Mandatory Class as per the Onion Structure

With Out AM Class We Cant Run Any Page in the OAF


23/23

PopList Item Creation Steps in the OAF:

Create the Item and set the item style as MessageChoice

Prepre the VO Under poplist.server package.

Set Below Properties to the Correpondent MessageChoiceBean Item.

PickListView DefinitionPickList View Display Attribute

Picklist Value Attribute

Note :

You Need to default any thing in the Poplist item set intial value property
