31.1.3 Adding the send service to the process model

Now that you have validated the WBICSend service, you can add it to the

process model by following these steps:

1. Copy the WSDL files for the WBICSend service to the

maintenance.processes package.

2. Open the process MaintenanceProcess in the BPEL editor.

3. Drag the WSDL WBICSendService.wsdl to the canvas.

4. Add a new invoke activity to the process and call it InvokeWBICSend.

activities.

8. In the From section, select Fixed Value and type some informative text in the

edit field.

9. In the To section, select Variable or Part. Select the contents of the process

output variable.

10.Connect the invoke activity to the Assign activity and the Assign activity to the

Reply node.

11.You need a transform activity to prepare the variable that is used in the

activity InvokeWBICSend. Call this new transformer PrepareWBICSend.

12.Add an extra connection from the InvokeAdapter_Progress to the

PrepareWBICSend activity.

Note: When the document has been sent to WebSphere Business Integration

Connect, we finish the process. When RedContract responds via WebSphere

Business Integration Connect, we trigger a new process (developed in 31.3,

“Building the receive process” on page 821) which invokes the adapter to

indicate completion of the maintenance request.
