How Siebel C/OM Can Be Used with SOA

Siebel customer order management can be used as a service by any SOA application though the process flow illustrated in Figure 4. In this flow:

• The external application UI first identifies (through a business process extraction layer) the right set of Web services that it needs to call to support the business process event.
• The external application layer then:
  • Identifies the right sequence of Web service invocations.
  • Prepares the input to these Web services, and generates the SOAP message appropriately.
• The Siebel Business Application server Web service listener will receive the soap message, and if needed, facilitates session management and converts the SOAP message to a native property set.
• The signal service invokes a COM signal, or calls the native service and invokes the COM order management workflow or business service to complete the task.
• Once the task is completed in the Siebel Business Application, the Siebel application returns a SOAP message back to the calling application which in turn extracts the output and updates the UI.
