### Using an Existing Application View Control

All controls follow a consistent model. Therefore, most aspects of using an existing Application View control are identical to using any other existing control. To use an existing Application View control:

1. Click Add on the Controls tab to display a list of controls that represent the resources with which your business process can interact.

Note: If the Controls tab is not visible in WebLogic Workshop, click View —> Windows —> Data Palette from the menu bar.

2. Choose Integration Controls to display the list of controls used for integrating applications.
3. Choose ApplicationView to display the Insert ApplicationView dialog.
4. In the Variable name for this control field, type the variable name used to access the existing Application View control instance from your business process. The name you enter must be a valid Java identifier.
5. In the Step 2 pane, choose the Use an ApplicationView control already defined by a JCX file radio button.
6. Click Browse to browse for existing Application View controls. The Select dialog is displayed. When you find the control you want to use, select it and click Select.
7. Click Create.

### Customizing an Application View Control

There are properties that are specific to the Application View control. If you choose to copy and customize an existing Application View control, the properties you may wish to modify are:

- av-identity
  For more information, see @jc:av-identity Annotation.
- av-service
  For more information, see @jc:av-service Annotation.

### ApplicationViewControl Interface

All Application View controls are subclassed from the ApplicationViewControl interface. The interface defines methods that may be called on Application View control instances from a web service.
