Guidelines for Customers

Overview

The Oracle Application Framework Developer's Guide documents the extensive set of features

and capabilities made available by the Oracle Application Framework. The information included

in this book is intended to provide our customers with a complete understanding of the

technology, tools, and standards upon which OA Framework based applications in the E-

Business Suite are built.

With Release 12, we now provide customers with many new features as well as tools to perform

certain types of customizations to OA Framework-based applications that were not available

with prior releases.

This document is intended to provide guidelines to customers regarding what prerequisites are

necessary to support certain features and what support options are available, for customizations

with OA Framework Release 12. In reviewing the capabilities and methods presented in this

document, it is very important that you realize that the type of resources available to support

your work, depends upon the extent and type of customization you plan to perform.

We expect that this document will be updated with additional information and details on an

ongoing basis. The most current version of this document is published in My Oracle Support

(formerly Oracle MetaLink) Knowledge Document 395441.1. Before starting any

customization work, it is essential that you review the latest version of this document.

Knowledge Document 389422.1.

Preface

Understanding the Available Support Options

Release 12 of the Oracle Application Framework (OA Framework) provides significant new

capabilities to perform personalizations, and extend OA Framework based web applications, in

a variety of ways. For a full description of available options, please refer to the Customization

Primer in the Oracle Applications Framework Personalization Guide. In this note, the use of the

term customizations collectively refers to those capabilities.

The objective of this note is to assist Oracle E-Business Suite customers with understanding the

level of support provided for the different types of customizations possible, including alternative

resources that are available for certain types of work, which fall beyond the scope of standard

support processes that customers may already be familiar with.

Personalizations

Personalizations performed within the scope of the OA Personalization Framework are a fully

supported means of customizing OA Framework based applications.

Due to its declarative nature and durable architecture, the OA Personalization Framework

continues to be recommended as the primary means for customizing OA Framework based

applications. The supported capabilities, methods and tools for performing personalizations are

documented in the Oracle Application Framework Personalization Guide. The most current

version of this Personalization guide is published in the Oracle E-Business Suite Documentation

Library, which is supplied on a physical CD in the Oracle E-Business Suite Release 12 software

bundle.

Access the latest content from the

Oracle E-Business Suite Online Documentation Library.

Methods or capabilities that not detailed in the Oracle Application Framework Personalization

Guide, fall beyond the scope of the OA Personalization Framework, and are not supported for

Oracle E-Business Suite installations.

Customers leveraging the capabilities of the OA Personalization Framework must ensure their

Release 12 instance is kept current with the latest OA Framework patchset applied. When

reporting issues against Personalization, Oracle Support will as a first step, require you to check

and confirm you have applied the most current patchset to ensure that the latest fixes for known

issues have been applied to your instance. You can find more information about the current

patchset, if available, including known issues addressed in that patchset by referring to the

latest Oracle Application Framework Release Notes on

My Oracle Support.

Extensions

Release 12 of the OA Framework and the accompanying Oracle 10g JDeveloper release

provide features for developing a new class of Oracle applications extensions not available to

customers in prior releases.

Assistance with customer-developed extensions is available via the following resources:

Oracle Application Framework Developer's Guide

• Oracle Application Framework Developer's Guide

The Developer's Guide fully documents the capabilities of the Framework including

instructions, examples and essential standards for implementing business-tier objects,

UI components and server-side features. Specifically, Chapter 9 of the Developer's

Guide under the section

Extending OA Framework Applications, provides instructions on

how to extend OA Framework based applications with custom business logic, including

detailed guidelines for BC4J code extensions.

• Oracle Application Framework ToolBox Tutorial Application

The ToolBox Tutorial application is a sample application accompanied by extensive

examples with step-by-step instructions that demonstrate the usage of business objects

and UI components to build OA Framework based application pages, against a simple

Purchase Order type application schema, installed on your Release 12 instance.

The ToolBox includes a specific tutorial lab on Extending OA Framework Applications.

• OA Framework Javadoc

Documents all core Oracle Application Framework packages and classes, including UIX

and BC4J objects extended by the Framework.

• OA Framework Discussion Forum on the Oracle Technology Network

OTN hosts a discussion forum for Technology - OA Framework . Navigate to

OTN

Forums under the E-Business Suite

(http://forums.oracle.com/forums/category.jspa?categoryID=3). You

can use the forum to post questions and exchange information with other customers on

the OTN community working on extensions. The OA Framework Development team and

Oracle Support will monitor and participate in some of the discussion threads on this

forum. Additionally, you may also consider participating in the

OTN JDeveloper forum for

usage questions concerning Oracle JDeveloper 10g.

• Oracle E-Business Suite Product Documentation

Some products may provide additional information on extending application specific

business objects and functionality. Consult

My Oracle Support

(https://support.oracle.com) under the respective product for more information.

For issues logged with Oracle Support to address questions concerning OA Framework based

extensions or usage of the OA Extension tool, Oracle Support will evaluate the nature of the

question, and in most cases refer the customer to one or more of the resources outlined above.

Important Limitations and Guidelines

Before starting work on any customizations, it is essential that customers be aware of the

following limitations and guidelines:

• Customers who intend to work with Oracle JDeveloper 10g OA Extension, and develop

extensions to their installed OA Framework-based self-service applications must use the

specific build of the Oracle JDeveloper 10g that corresponds to the OA Framework

Release 12 installed in their runtime environment.

Please consult the corresponding "About Oracle E-Business Suite Technology

Update" document for the JDeveloper ARU that corresponds to the Release 12

ATG patchset you install.

Preface

• Oracle does not provide access to Java source code for OA Framework or products.

You should consider the Developer's guide and available Javadoc for the classes you

are working with as the only documented sources of information available to determine

the characteristics of the object you are extending.

• Design-time options and expected run-time behavior of OA Framework components are

fully documented in the Developer's Guide and Javadoc mentioned above.

• In order to log issues with Oracle Support concerning components, such as unexpected

run-time behavior of a component, customers will be required to provide a simple

reproducible test case

written against the OA Framework ToolBox Tutorial schema or an

E-Business Suite product schema. The test case must not rely on any custom schema

elements or custom class libraries, and must be runnable by Oracle Support without any

custom dependencies.

• Oracle does not recommend that customers extend controller objects associated with

regions or web beans in shipped E-Business Suite product pages. Controller class

(oracle.apps.fnd.framework.webui.OAControllerImpl) methods should

effectively be considered private, since their implementation is subject to change.

Controller extensions are therefore not considered to be durable between upgrades. If it

is absolutely essential to handle custom form submit events on a shipped product page,

processFormRequest() is the only method that should be overriden in a controller

class, although the risks outlined above still apply.

• Customers are fully responsible for all custom code written to support customer-

developed extensions. This includes any custom Look-and-Feel (or custom skin) that

you develop and deploy. Oracle Support and Oracle E-Business Suite development will

not review custom code or custom skins. Questions such as those relating to design,

and usage of components to develop extensions, will generally be redirected to the OTN

forums mentioned above.

• Each release of Oracle E-Business Suite is associated with a standard Look-and-Feel /

skin. Oracle only supports Look-and-Feel issues on the standard Look-and-Feel for that

release, and not for any other Look-and-Feel, including sample skins such as "Minimal

Look and Feel" and "Simple Look and Feel" that are provided as basic references for

custom skin development.

• To facilitate transparent upgrades and new feature uptake, custom code must comply

with the Oracle E-Business Suite OA Framework coding standards described in Chapter

8 of the OA Framework Developer's Guide

• .

• Customers planning to undertake advanced or complex extension projects may consider

engaging services available from Oracle Consulting or Oracle Partner resources. Oracle

Consulting and Partner organizations offer an alternative means of support through

consulting resources who have been specially trained or certified on OA Framework and

Oracle E-Business Suite technology. For more information on what options are

available, please refer to the information under

Oracle Consulting Services

(http://www.oracle.com/us/products/consulting/index.html) and the

Oracle Partner Network (http://www.oracle.com/partners/index.html).
