OAF Basics on Extensions

Java Concepts

Classes Packages Inheritance can be defined as the process where

one object acquires the properties of another

public class Animal public class Mammal extends Animal public class Reptile extends Animal public class Dog extends Mammal

OAF is web development framework based on MVC architecture for developing HTML pages and customizations in the Oracle Applications 11iR12

Model 1048766Data 1048766Implemented using Oracle Business Components for Java (BC4J) 1EO (Entity Object) 2VO (View Object) 3AM (Application Module)

View 1048766User Interface 1048766Implemented using an Oracle technology called UIX

(UIX = User Interface XML)

Controller 1048766Code 1048766User actions are handled by the OA Controller

(Ex Clicking SUBMIT button)

Entity Object is based on database table or other data source1048766

Entity Object contains attributes which represent database columns1048766

All insertupdatedelete (DML Operations) transactions go through EO to database

Eg oracleappsicxporschemaserverPORequisitionLineEO

Two types1 SQL based ndash eg ApprovalListVO2 EO based Represents a query result Is used for joining filtering projecting and sorting

your business data Can be based on any number of entity objects

(EOs) and provides access to EOs

Think of AM as a broker between your Client Activity and database activity It also manages the state of database transaction

Responds to user actions and directs application flow

Model objects like EO and VO cant be accessed directly from the Controller Class except AM

Contains methods such as 1 Process Request Fires when OAF page loads

for the first time 2 ProcessFormRequest Fires when user submits

the page(Ex clicking SUBMIT button)

The dbc file is mostly used to define database parameters stands for database connect descriptor file used to connect to database it authenticate users against database in FND_USER table

Project Customization

Steps to extend Controller Class 1 FTP all the required sub-directories from $JAVA_TOP to

myclasses This includes all class files and all the xml files 2 FTP the same sub-directories from $JAVA_TOP to

myprojects 3 Decompile the class files in myprojects and name those

decompiled files to java jad -o -r -sjava -dsrc Djadoracleappsclass

4 Delete the class files from myprojects 5 FTP the xml files from $PRODUCT_TOPmds to myprojects 6 Import the required BC4J files that you wish to debug 7 Extend the controller 8 Add the extended controller to the region using personalization

Controller Extension public class AgappsEditApproversCO extends EditApproversCO

processRequest DeleteRadio Button made the default selected option All Approver Checkboxes are checked

processFormRequest On clicking of submit button If Number of checked boxes = total number of approvers

Display error message Please ensure at least one approver is selected

public class AgappsReqApprCO extends ReqApprCO

processRequest Get the total number of approvers If this count lt=1 Disable the Manage Approvers Button

processFormRequest When the user clicks the Next Button If the approver count =0 Get count of unchecked approvers If count = 0 display error message Please select approver(s) from the Manage Approvals page
