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.

  • Services advertise and provide an entry point for messages sent from the outside world to the SOA composite application. Services are created in the Exposed Services swimlane of the SOA Composite Editor.
  • References enable messages to be sent from the SOA composite application to external services. References are created in the External References swimlane of the SOA Composite Editor.

The binding component for a web service contains the following:

  • A Web Services Description Language (WSDL) file that describes service capabilities
  • The binding connectivity that describes the protocols that can communicate with the service (a web service using the simple object access protocol (SOAP))

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.

drag web service into editor

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.
