Concept

 Controller (CO)
 Application Module (AM)
 View Object (VO)
 Entity Object (EO)
 Page, Region & Region Items

Concept - Controller (CO)
 A controller in OA Framework is a Java class that is attached to
a region. It is mainly responsible for page rendering and
respond to and handle user actions
 Based on OAController interface (3 methods)
– processRequest(): called by OA Framework just before a region
gets displayed
– processFormData(): invoked when a user submits the page
– processFormRequest(): invoked if processFormData() does not
raise any unhandled exceptions
 Common Parameters
– OAPageContext: provides application context and also the current
user’s session-related details
 get parameter values passed to the page
 get a handle to the Root Application Module
 navigate to another page
– OAWebBean: Use this parameter to get a handle to any of the
beans within an OAF page

Concept - Application Module (AM)

A broker between the User Interface and
Database Object [VO and EO]
 Every OA Framework page accessed
through Oracle Applications must have an
Application Module attached to its top-level
region
 Application modules can also be attached at
lower-level regions within the page (i.e.
Nested AMs

Concept - View Object (VO)

 query data from database
 can be SQL or EO based

Concept - Entity Object (EO)

 include all columns of a corresponding table
 responsible for doing inserts, updates, and
deletes to database tables
 each instance of an entity object represents a
single row in the database table

Concept - Page, Region & Region Items

A page consists of regions, and the region
can consist of various region items. Regions
and region items can be of differing types.
They can also be nested within other regions.

Tools

 JavaDecomplier
 JDeveloper
 Browser (with Developer Mode)

Tools - Java Decomplier

 Decompile java .class files (CO / VO / EO
etc.)
 E.g. Cavaj

http://cavaj-java-decompiler.en.softonic.com

Tools - JDeveloper

 Determinethe right version of JDeveloper
Metalink Note: 416708.1

Tools - Browser

 IE - Developer Mode

Tools - Browser

 Firefox – Firebug Plug-in

Setup

 Environment Variable
 Java Packages
 Page / Region XML Files
 DBC File
 Profile Options

Setup – Environment Variable

 JDEV_USER_HOME

E.g. C:JDeveloper9ijdevhomejdev

Setup – Java Packages

 Standard Package Convention
– e.g. Package oracle.apps.ap.oie.webui -> Path:
$JAVA_TOP/oracle/apps/oie/webui
 Extension Naming Convention
– adding company name as a prefix
– e.g. Package pag.oracle.apps.ap.oie.webui ->
Path $JAVA_TOP/pag/oracle/apps/oie/webui

Setup – Java Packages

 Download class files & server.xml
– Save to <JDEV_USER_HOME>myclasses
– E.g.
C:JDeveloper9ijdevhomejdevmyclassesoracleappsapo
iewebui*
– Some important classes:
 $JAVA_TOP/oracle/cabo/*
 $JAVA_TOP/oracle/jbo/*
 $JAVA_TOP/oracle/svc/*
 $JAVA_TOP/oracle/apps/fnd/common/*
 $JAVA_TOP/oracle/apps/fnd/framework/*
 $JAVA_TOP/oracle/apps/fnd/wf/*

Setup – Page / Region XML Files

 Download xml files
– Path: <APPLICATION_TOP>/mds/*
– e.g. $AP_TOP/mds/oie/webui/*.xml
– Save to <JDEV_USER_HOME>myprojects
– e.g.
C:JDeveloper9ijdevhomejdevmyprojectsoracle
appsapoiewebui*
– (Note: does not have to create "mds" folder)

Setup – DBC File

 Contains all the information (except
password) required to establish a database
connection
 Download From $FND_SECURE
 Save to
<JDEV_USER_HOME>dbc_filessecure

Setup – Profile Option

 Personalize Self-Service Defn
– must be set to Yes for personalizations to be
performed
 FND: personalization region Link Enabled
– enable personalization links at region level.
 FND: Diagnostics
– An About this page link appears at the bottom of
every OA Framework page

Methods

 “About this Page”
 Personalization
 Extension
– CO Extension
– VO Extension and Substitution
– EO / AM Extension
 Modification of existing classes (not preferred)

Deployment

 Page / Region XML Files
 VO Substitutions
 .class files (e.g. CO Extension)

Deployment - Page / Region XML Files

 Step 1 – import.bat
– cd C:JDeveloper9ijdevbinjdevbin
– import
C:JDeveloper9ijdevhomejdevmyprojectsoracleappsapoie
webuiOIEMAINPAGE.xml -username apps -password apps
-rootdir C:JDeveloper9ijdevhomejdevmyprojects
-dbconnection
"(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL
=TCP)(HOST = pagdisc.local)(PORT=1523)))
(CONNECT_DATA=(SERVICE_NAME = UAT)))"

Deployment - Page / Region XML Files

 Step 2 – Clear MDS Cache
– Login as Functional Administrator

Deployment - VO Substitutions

 Step 1 - jpximport.bat
– cd C:JDeveloper9ijdevbinjdevbin
– jpximport.bat
C:JDeveloper9ijdevhomejdevmyclassesPAGO
IE.jpx -username apps -password apps
-dbconnection
"(DESCRIPTION=(ADDRESS_LIST=(ADDRESS
=(PROTOCOL=TCP)(HOST = pagdisc.local)
(PORT=1523)))
(CONNECT_DATA=(SERVICE_NAME = UAT)))"

Deployment - VO Substitutions

 Step 2 – Bounce mid-tier
– $COMMON_TOP/admin/scripts/adstpall.sh
apps/<apps_password>
– $COMMON_TOP/admin/scripts/adstrtal.sh
apps/<apps_password>

Deployment - .class files

 Step 1 – Upload .class files
– Upload .class files to $JAVA_TOP (e.g.
$JAVA_TOP/oracle/apps/ap/oie/webui)
 Step 2 – Bounce apache
– $COMMON_TOP/admin/scripts/
$TWO_TASK*/adapcctl.sh stop
– $COMMON_TOP/admin/scripts/
$TWO_TASK*/adapcctl.sh start
