ORACLE APPLICATION FRAMEWORK
Oracle Application Framework (OA Framework) is the Oracle Applications development and deployment platform fo
HTML-based business applications.
Simple Web Application Architecture ( Servlet / JSP ) :
Client Tier Application - Tier Database - Tier
HTTP Request
HTTP Response
Initially Web Application was very simple ( developed in 1990s )
Application Tier Contains a Web Server which maintains the components such as Servlet, JSP
Component :Component is piece of code, which implements well defined interface.
A Single Component is not an Application.
An Application consists many no.of components working together.
Component handles complete task, such as Business Logic, Database Transactions Logic and Presentation Logic.
Disadvantages :
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 PresentationLogic.
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 beingdeveloped as single component.
To overcome the above disadvantages MVC1 Architecture was introduced

MVC1 Architecture :
M Model V View C Controller
Client Tier Application - Tier Database Tier
HTTP Request
HTTP Response
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 user interface reacts to the users input. The Controller component is the object thatmanipulates the model or data object.
In MVC1 Architecture
Servlet / JSP acts as View as well as Controller.
Java Bean acts as Model Component.
Disadvantages :
1) Only One Application developer has to develop the component with Business Logic, as well as Presentation Logic.
2) Application developer has to concentrate on Business Logic as well as Presentation Logic.
3) Application Developer Must have the Multiple Skills
4) Resources such as Java developers and Web developers can not be used effectively
5) Development Time is more
6) Lot of confusion with Business Logic, Presentation Logic since they are being developed as single component.

MVC2 Architecture :
Struts Frame work follows the MVC2 Architecture
Client Tier Application - Tier Database Tier
HTTP Request
HTTP Response
Servlet acts as Controller
JSP acts as View
Java Bean acts as Model
Controller:
It is java Servlet called as Action Servlet. It receives request from the web client and stores data into the Java Beancalled as Form Bean (Model) and receives response (success / fail) from the Form Bean. Based on the response from FormBean, Action Servlet decides, which page (view) to be presented to the client.
Model :
It is Java Bean called as Form Bean. It will receive the client data through the Controller and performs the datavalidations or data base transactions such DML and DQL operations. After performing database transactions it provides thedata for the view.
View :
It is a JSP. It populates the data from the Form Bean ( Model ) and Present to the user.

Oracle Application Frame Work Architecture :
Architecture of Oracle Application Frame Work is similar to the Struts Frame Work but some difference are there.
Client Tier Application - Tier Database Tier
HTTP Request
HTTP Response
AM Application Module VO View Object EO Entity Object
Controller :
It is a Java Class. OAControllerImplis a parent of all Controller Classes. Controller performs data base transactions through the Application Module interface. It will get the data through the Application Module and Push into the View.
View :
It is JSP with GUI Components. It populates data of its GUI components through the Controller.
View never Interact with the Model Component.Model :
It is a combination of Application Module, View Object and Entity Object.
Application Module :
It is an interface given to the Controller Classes. It can be shared by multiple controllers. It performs DQL operations through the View Object It performs DML operations through the Entity Object. OAApplicationModuleImpl is a parent of Application Module Class.
It is mandatory for all applications
View Object :
SQL Query ( SELECT statement to project the data in the form )
It should be stored in .server package
View Object can be developed manually or BC4j wizard
OAViewObjectImpl :is the parent of all view objects

Entity Object :
It is database object such as table, view and etc
DML operations will be performed on the Entity Object
It should be stored in schema.server package
OAEntityImpl : is the parent of all Entity Objects
Onion Architecture of OA Framework
OA Framework can be extracted into a series of concentric layers, like an onion.
Each layer communicates with it top and bottom layers.

Regions in the OAF
Region is a area in the page.
It holds list of Items
Region is used to obtain desired layout in OA Frame Work
Region follows embedded ( nested ) properties
Default Layout of the Region isPageLayout
It follows the java beans hierarchy
The regions in the same node level are called as SIB
LINGS .
The regions inside the another region are called as SUB REGIONS or CHILD
There are two types of regions 1) Internal Regions and 2) External Regions
Different Styles of RegionRegion Style :
Header
Text :Oracle Frame Work ( as desired )
defaultSingleColumn
Right Justification
defaultDoubleColumn
to arrange the items in tow columns
messageComponents
to place the message components in the Rows and column
components such as Text Items, ChechBoxes, Text Editor, Choice,
RadioGroup, RadioButtons and etc
Rows : 2Coulmns : 4
( here priority will be given to columns . Alignment is based on no.of Columns )

CREATION OF LOV
LOV can be created in two ways 1) Internal Region 2) External Region
Internal Region is only for specific LOV item
External Region is for rusability. It can be shared by multiple LOV items.
Steps to create LOV with internal Region :
1) Create item with itemStyle as messageLovInput
2) Create the VO inside the package called lov.server and Shuffle VO to AM ( optional )
3) Add VO to Item by using Wizard
4) Set one of the item property search allowed : true
5) Set the following LOV mapping

The LOV can be on the existing Page or New Page as per the requirement
Eg:
Creation of a page( like previous process )
Right Click on Project file ( .jpr ) New Web Tier OA components Page OK
Name : DemoLovItemPG ( as per naming conventions Page must end with PG)
Package : test.oracle.apps.po.orgid.webui
1) Create the item :

Create item1 with Item Style as messageLovInput
Region2 ( Header ) Rt.Click item
Item properties :
Id : organizationID
Item Style : messageLovInput
Prompt : organizationID
When the item style set as messageLovInput, then following will be generated automatically under the item
1) Region3
2) lovMappings
2) Create VO inside the lov.server package
a)Create package : ( test.oracle.apps.po.orgid.lov.server )

Working with Controllers :
Controller is a Java Class. It is used to capture the user actions, events also to perform business logic in the application .
It controls the application flow
It should be placed inside of the webui package
Naming Convention is ends with CO
Eg:
Page Name : DemoPGController Name : DemoPGCO
Package Name : test.oracle.apps.po.login.webui.webui
Controller is only .Java file no other files
The parent class for any controller is OAControllerImpl
Controller provides following methods
1) proceesRequest ( OAPageContext pageContext, OAWebBean webBean );
2) proceesFromData ( OAPageContext pageContext, OAWebBean webBean );
3) proceesFormRequest ( OAPageContext pageContext, OAWebBean webBean );
processRequest ( OAPageContext pageContext, OAWebBean webBean );
It will be executed before loading the page. It is used for initializations. Like a doGet() in Java or pre-form triggers in
D2k application.
processFormRequest ( OAPageContext pageContext, OAWebBean webBean );
It will be executed after loading the page. Like a doPost() in Java or post-form triggers in D2k application.
processFromData ( OAPageContext pageContext, OAWebBean webBean );
This is used implement the business logic such validation, DML operations and etc.
pageContext: is variable to read value, messages from the client and also used to call another page
webBean : is a variable to send the response to the client and to control the bean properties dynamically

Prepared Statement
It is a pre-compiled statement at the database server. This statement is used to improve the performance of theapplication.
5/20/2018 OAF Basics
32/84
Raaj NagulapalliM.C.A
32
Steps to write thePrepared Statement
1) Get the connection reference from the database
Connection con= this.getOADBTransaction().getJdbcConnection(); ( inside of xxxxAmImpl.java)
// this refer to xxxxAmImpl instance
2) Write the prepared statement
PreparedStatement pst= con.prepareStatement("INSERT INTO STUDENT VALUES ( ? ,? , ?)");
? is a place holder . it will referred with index 1, 2, 3
3) Set the values on the place holder
Eg: pst.setInt(1, 1001);
pst.setString(2, Chandra);
pst.setInt(3, 25);
4) Execute the Query
int num = pst.execute();(or)
int num = pst.executeUpdate();
the above returns no.of records INSERTED / DELETED / UPDATED in the database.
5) Commit the transaction
con.commit();

Callable Statement :
Callable Statementis an interface from java.sql packageIt is used to execute the stored procedure
5/20/2018 OAF Basics
37/84
Raaj NagulapalliM.C.A
37
Stored Procedure :
It is a set statements at the database server. It contains statements such as SELECT, INSERT, DELETE, UPDATE and alsostatements to perform validations
It carries three types of parameters
1) in to pass the value
2) out
to return the value3) in-out to pass as well as to return the value
Advantages in using stored procedure :
1) It improves the performance of the application2) Since Stored Procedure is storing at the database server it can be shared by multiple clients.
Steps to prepare the callable statement
1) Get the connection reference from the database
Connection con=this.getOADBTransaction().getJdbcConnection(); ( xxxxAmImpl.java)// this means xxxxAmImpl instance
2) prepare the callable statement
CallableStatement cst = con.prepareCall( { CALL sp_test ( ? , ? , ? , .. )};CALL is key word to call the stored procedure at the database server.
3) Register the parameters
1) in parameters : these are default parameter. Hence it is an optional to register directly value can be passed
Eg.cst.setInt(1, 1001)cst.setString(2, hello);
2) out parameters :
cst.registerOutParameter(3, Types.VARCHAR)
Once the parameter registered as out parameter, then value can not be passed.
setX() should not be used after registering as out parameter. It throws SQLException.
3) in-out parameter :
cst.registerInOutParameter(4, Types.INT);
cst.setInt(4,2007);
4) Execute the Callable statement
cst.execute();
5) Read the out parameters

38
String str = cst.getString(3)
int num = cst.getInt(4);
Types:
It is an interface from java.sql package.
It provides the constants to map with the database data types.
Types.BIT Types.BOOLEAN Types.SMALLINT Types.TINYINT
Types.INTEGER Types.BIGINT Types.NUMERIC Types.DECIMAL;
Types.FLOAT Types.REAL Types.DOUBLE Types.CHAR
Types.VARCHAR Types.LONGVARCHAR Types.TIME Types.TIMESTAMP
