Calling a PL/SQL function from ADF using JDeveloper 11G TP4



I will go over how to call a PL/SQL function from Jdeveloper 11G Tp4


First create a function that you will use , for this I used JDeveloper's database editor


Then create an ADF project and an Application Modulu within the new project. Follow the wizard until the Java screen, there we need to
check the first check box to generate the Java class file for the application module.
























Once you are done with the wizard you will see that a Java file was created under the application module.






Edit this file and add the a public method to call the PL/Sql API. For more information you can check the developer's guide documentation.












Now we need to expose this function .
To do this edit the application module and go to Java tab. There click the pen for client interface. You should the newly created function on the left side. Select it and move it to right.














After completing the previous step you
should be seeing your function under Data controls.


Everything is ready now. We need to create a page and drag and drop the data control on to the page




While dropping the data control on toyour page select ADF Parameter Form from the coming menu as in the left picture.This will create the form to call your function.




Once the form is created there is one more thing to do. We need add a field to see the result of the
function. To do this drag and drop the String item on the data control on your page as an output field as on the left.




Now we can run our page and test it.

There is no straight way to that. You may create a transient view object and define your LOV there.

Hi Soyer,
Thanks for the hint!
But it is possible to do that using EJB3/JPA?

Thanks,
