WorkflowRuntime workflowRuntime = new WorkflowRuntime(); ExternalDataExchangeService dataExchangeService; dataExchangeService = new ExternalDataExchangeService(); workflowRuntime.AddService(dataExchangeService); PaymentProcessingService paymentProcessing; paymentProcessing = new PaymentProcessingService(); dataExchangeService.AddService(paymentProcessing);
With the code above, our application can use paymentProcessing.RaiseXXXXEvent to interactive with the workflow instance. My question is : What's the principle to implement such a mechanism. I think this is a kind of Event Driven
Pattern, but how can I implement this mechanism and why ? Please point me the direction or any references are appreciated.
By the way, is there the mechanism in jBPM ? Does jBPM include sequence workflow and state machine workflow like window workflow foundation ?
