public class D2WCustomComponent
extends D2WComponent

The D2WCustomComponent class is a component that allows you to use a WebObjects reusable component as a property-level component. You can use the Web Assistant to specify the name of the reusable component to embed.

D2WCustomComponent passes two bindings to the reusable component:

• object -- the object containing the property to modify or display
• key -- the key for the property to modify or display.

See the "Customizing a Direct to Web Application" chapter in Developing WebObjects Applications With Direct to Web for more information about this component.
