Create a service with appropriate inputs to call the undercover agent (UCA) to send the event.

Before you begin

To perform this task, you must be in the IBM® Process Designer desktop editor, which is deprecated.

About this task

The next step in completing this sample inbound integration is to create an Integration service to call the UCA to send the event when the inbound web service (that you create in the following section) is called.

Procedure

  1. Open the desktop Process Designer (deprecated).
  2. Open a process application in the Designer view.
  3. Create an Integration service and name it Inbound WS Handler or something similar. (If you need detailed instructions, see Building an Integration service.)
  4. Drag an Invoke UCA component from the palette, name it My UCA and place it between the Start Event and End Event in the service diagram.
  5. Use the Sequence Flow tool to connect the service components on the diagram.
  6. Click the Invoke UCA component in the diagram.
  7. Click the Variables tab, and then click the Add Input button to add the someString variable as an input variable.
  8. Save the changes.
  9. Select the Implementation option in the properties.
  10. Click the Select button next to the Attached Undercover Agent field and pick the Undercover Agent that you created in the preceding procedure, My UCA.
  11. Select the Data Mapping option in the properties.
    The Input Mapping is automatically set to the someString variable from the UCA.
  12. In the field next to the variable, type tw.local.someString. This sets the input value of the UCA to the local value of the someString variable, which enables you to test the implementation in the Inspector as instructed in Testing the integration.
    The value is used in the business process definition correlation mapping that is created in the initial task.
    Note: The someString variable is available only if you create the attached service as instructed in Creating an attached service and the UCA as instructed in Creating an undercover agent before performing the steps in this procedure.
  13. Save your work.
