VO substitution steps in oaf

In this post , I will share VO substitution steps in oaf. What it means vo substitution oaf. VO substitution means to put the customize VO in place standard VO. So this customize VO will substitute that Standard VO in each place where It was using earlier in the OAF pages. Now after the VO substitution , the new customize VO will be work in place of Standard VO. This process is called VO substitution. vo substitution Requirment comes when we have an requirement to show some additional information's in the OAF page , for which our standard VO is not have that information's so for this case we creates our customize VO and then substitute this Customize VO with the Standard VO so that this customize VO can work on the OAF pages in place of the Standard VO. vo substitution oaf has some rules ,which we need to follow while doing vo substitution other wise we can get errors during runtime of the OAF page in application. Here below is the Detail VO substitution steps in oaf.

VO substitution steps in oaf:-

1.Indentify that Which VO we need to Extend
2. Download the VO from Oracle Java_Top Location to Your Local Desktop under My Projects folder of Your JDev setup.
3.Then We create New view Object(VO) which extends the Standard View Object.
4.Then We substitute the New Custom View Object with the Standard View Object.
5.Then we upload the New Custom View Object to Oracle Java_Top Location.
6.Then we Register the New View Object in the Oracle application Through XML Importer script.
8.After Import/Register , We add the new field in the OAF page through Personalization and then give reference in this Field for the New Custom View Object(VO).

Step1:- First Go to your OAF page in the application , in which you will do View Object Extension.
This is the Page in which we will do View Extension. Here I want to display the DFF attribute5 in this Track Submitted Expense Reports Status Window.

Step2:- To see the Properties of this Page and to know which View Object is working behind this Page. for this we need to go to 'About this Page' in the Bottom of the Page.

Step6:-
 Now you get to know that where is your Standard View Object is Placed in the Oracle application Under Java_Top.

Then you Need to go to Server Under Java_Top then Under Java_Top follow the same path 'oracle/apps/ap/oie/webui/' and copy the 'TrackExpesneReportsVO' from Server to your Local Desktop.

One Important Thing.

You need to create the same path in your JDev folder under' 'jdevhome'
Under JdevHome there is MyProjects' folder under this folder you have to Create same folder structure like oracle/apps/ap/oie/server/' and then this copied file 'TrackExpesneReportsVO' in this Location.

The rule is you have to create same folder structure like the Folder Structure created for The Standard Controller in the Application server Java_Top.
