Service

Chapter 19 Working with Sybase Unwired Orchestrator

Service

A service is an interface to an external business process. WSDL is used to describe this service. The WSDL file contains the description of the entire web service expressed by several port types. Each port type defines different operations.

Unwired Orchestrator supports the following types of web service operations:

OneWay (Send) operation that only sends messages
Notification (Receive) operation that only receives messages
RequestReply operation that sends requests to a database and receives results sets

Unwired Orchestrator allows you to browse through web services, visualize WSDL files and extract documents description from WSDL files. However Orchestrator always copies WSDL files in the project.

Mapping

You design an Orchestrator service, port type and operation the following way:

Unwired Orchestrator concept	PowerDesigner concept
Service	Service provider
Port type	Interface
Operation	Operation

The following stereotypes are available to define the service type on a service provider object:

<<Database>>
<<Messaging>>

Extended attributes

The following extended attributes are available:

Extended attribute	Description
ImportedWsdlContent	Contents of the original reversed WSDL file
Namespaces	List of namespaces defined in the header of an imported WSDL file
prefixForUse	XML Prefix used by the process to reference the service provider
prefixSchemaNspc	prefix for schema namespace

Insert Map
You can easily insert a Map between two services by right-clicking the flow between them and select Insert Map from the contextual menu. For more information on maps, see section Assign and map activities.
