Siebel source definitions represent Siebel metadata. You can import Siebel source definitions through the Java Data Bean API. When you import a Siebel source definition through the Java Data Bean API, the Designer extracts the metadata from the business components on the Business Objects Layer.
Use the Import from Siebel Wizard to import Siebel business components. When you import a Siebel source definition, the Designer displays business objects for the active application object manager. You can select a business object and then a business component to import from the list of business components.
