### Using an Existing WLI JMS Control

All controls follow a consistent model. Therefore, most aspects of using an existing WLI JMS control are identical to using any other existing control. To use an existing WLI JMS 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 WLI JMS to display the Insert Control - WLI JMS dialog.
4. In the Variable name for this control field, type the variable name used to access the existing WLI JMS 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 a WLI JMS control already defined by a JCX file radio button.
6. Click Browse to browse for existing WLI JMS controls. The Select dialog is displayed. When you find the control you want to use, select it and click Select.
7. Click Create.
