Part1 Controller Extension In OAF :How to add code in Controller Extension on Button Click Event

 

We will do today controller Extension in Oracle Application OAF pages. We need Controller Extension when we want to add custom Validations and to add extra monitoring in the Standard process or to Control the Standard Page behavior  then we do Controller Extensions to achieved this requirement. We can control the functionality of the Page through Controller codes and if we want to control the Standard OAF pages then we do OAF Controller Extensions.

 

Test Case:- In this example , I will do Controller Extension in the Expense Reports Home Page. Suppose your Business requirement is  that When ever user will withdraw his expense report then it will create history in the Custom table that how many times this particular Expense Report's  Withdraw and on which date. So lets start to do this.

Step4:- Now you know the Controller Name but you also need to get  the Location of the Controller in Oracle Application to so Controller Extension.

This is the Location of the Controller under Java_Top under which you will do Extension.

Step5:- Now you get to know that where is your Standard Controller 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 'TrackExpesneReportsCO' 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/webui/' and then this copied file 'TrackExpesneReportsCO' 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.

Step10:- Now Give the Name of the Project same like OA workspace.

Package Path:- Choose the same like Standard Controller but choose the application Top start with xx like this this change 'xxap'.
