To create a subscription

3. Click Add.

4. In the Add New Subscription wizard, type a name in the Subscription Name text box.

5. (Optional) Type a description in the Subscription Description text box.

6. In the Notification drop-down list, select a notification, then do one of the following:.

Click Next and follow the instructions in the wizard to customize the subscription view locations and name, managed bean name, managed bean scope, and Java attributes.

Click Finish to accept the remaining configuration parameters as defaults.

7. Save your changes.

8. After you click Finish, the wizard creates a subscription bean and a subscription provider, and opens a template subscription view in the editor. You can customize this view to your own needs, as described in Configuring the Default Subscription View. The view contains these components:
