  1. 1. OAF Development Guide
  2. 2. Concept Controller (CO) Application Module (AM) View Object (VO) Entity Object (EO) Page, Region & Region Items
  3. 3. 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
  4. 4. 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
  5. 5. Concept - View Object (VO) query data from database can be SQL or EO based
  6. 6. 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
  7. 7. 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.
  8. 8. Tools JavaDecomplier JDeveloper Browser (with Developer Mode)
  9. 9. Tools - Java Decomplier Decompile java .class files (CO / VO / EO etc.) E.g. Cavaj http://cavaj-java-decompiler.en.softonic.com
  10. 10. Tools - JDeveloper Determinethe right version of JDeveloper Metalink Note: 416708.1
  11. 11. Tools - Browser IE - Developer Mode
  12. 12. Tools - Browser Firefox – Firebug Plug-in
  13. 13. Setup Environment Variable Java Packages Page / Region XML Files DBC File Profile Options
  14. 14. Setup – Environment Variable JDEV_USER_HOME E.g. C:JDeveloper9ijdevhomejdev
  15. 15. 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
  16. 16. Setup – Java Packages
  17. 17. 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/*
  18. 18. 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)
  19. 19. 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
  20. 20. 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
  21. 21. Methods “About this Page” Personalization Extension – CO Extension – VO Extension and Substitution – EO / AM Extension Modification of existing classes (not preferred)
  22. 22. Deployment Page / Region XML Files VO Substitutions .class files (e.g. CO Extension)
  23. 23. 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)))"
  24. 24. Deployment - Page / Region XML Files Step 2 – Clear MDS Cache – Login as Functional Administrator
  25. 25. 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)))"
  26. 26. 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>
  27. 27. 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
