To view the discussion, visit: http://community.jboss.org/message/561037#561037 -------------------------------------------------------------- Does jBPM include sequence workflow and state machine workflow like window workflow foundation ? If someone is familiar with windows workflow foundation, please have a look at the following problem: 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. Any similar implemented in jBPM ?     -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/561037#561037] Start a new discussion in jBPM Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
