You create the View Row methods that you want to export in its containing View Object's .java file. Follow these general steps:
In the Navigation pane, right-click the View Object name, and select Edit. In the Java tab, select Generate Java file and Generate accessors for the View Row class. Click Apply.
In the Client Row Methods tab, select the accessor methods you want to expose. Click Finish. JDeveloper creates a remote interface, named for the View Row, that contains the signatures of the exported methods.
(Optional) In the generated Java file that implements your View Row, you can add business logic to the row accessor methods you will expose to the client.
Include the methods in a remotable Application Module.
Once you have the remotable Application Module, deploy it to the application tier.
