Using the Application Builder, a user can configure the Weblet (contained in a Bundle) that implements the Application's specific behavior. Initially, an Application will have no Weblet associated with it. An Application without a Weblet is of no value (does nothing). So to add a Weblet to the Application, click the "Add" button. This will allow you to associate a new Weblet to the Application. Adding a new Weblet will take you to the Weblet Add screen where you will set the necessary Weblet attributes and save them. This includes choosing the specific Weblet Bundle implementation. Once saved, you will be returned to the Configure Application screen. The "x" button will delete the current Weblet from the Application and allow you to associate a different Weblet to the Application if you so choose.
