After you create your slot component, you can use Scenarios to determine under what circumstances a gear will be displayed in a slot. The Creating Scenarios chapter in the Personalization Guide for Business Users provides information about how to create a scenario.

For example, you could create a scenario that adds a poll to a portal user’s home page upon login, and removes the poll after the user has voted in the poll. To do this, create a new scenario with the Logs in event followed by the Add items to slot action segment, and the Poll vote event followed by the Remove items from slot action segment:

The following JSP example shows how you might use a slot to render a gear. It assumes you’ve created a slot named /com/acme/slots/MyGearSlot. The TargetingFirst servlet bean is used to display the appropriate gear.
