Oracle Service Bus defines proxy services and business services in terms of two WSDL ENTITIES:

• The abstract WSDL interface, which defines the operations in that interface and the types of message parts in the operation SIGNATURE
• The binding WSDL interface, which defines the binding of the message parts to the message (packaging), and the binding of the message to the transport 

WSDLs can be imported into the WSDL repository USING the Oracle Service Bus Administration Console. The Oracle Service Bus Administration Console can also be used to resolve the references in the WSDLs, to ensure all schemas and WSDLs are linked correctly. After WSDLs are stored in the repository, they are available for use when adding proxy services and business services. Oracle Service Bus USES its own REPRESENTATION of the interface for messaging services.
