Binding components such as web services make SOA composite applications accessible to the outside world. There are two types of binding components in an SOA composite application: services and references.
The binding component for a web service contains the following:
You add a web service to an SOA composite application by dragging it from the Component Palette into the Exposed Services swimlane of the SOA Composite Editor. This provides the entry point for messages sent from the outside world to the SOA composite application.
This invokes the Create Web Service dialog for creating a binding component service that provides a SOAP protocol entry point into the SOA composite application for the outside world. You create the WSDL file and port type for the service by selecting the Generate WSDL from schema(s) icon to invoke the Create WSDL dialog. This dialog enables you to create a standard WSDL file that describes service capabilities.
