These scenarios show how the service-oriented integration business patterns can be implemented. These business patterns are as follows:
In the scenario shown in the following diagram, the process integration business pattern is implemented using BPEL.
Trigger:
An application places a message in the queue.
Primary flow:
A variant of the previous scenario has the business rules externalized in a rule engine, in order to simplify the condition logic in the integration process. This corresponds to the external business rules variant of the process integration business pattern, and is shown in the form of a scenario in the following diagram:
Trigger:
The JEE application sends an SOAP request.
Primary flow:
In this variant, the integration process is initiated by a time-based event. In this case, a job scheduler added before the BPEL process triggers an event at a specified time, which starts the process instance. The process is started by the scheduler via a web service call. The following diagram shows the scenario:
Trigger:
The job scheduler building block does a web service request at a specified time.
Primary flow:
In this scenario, additional user interaction is added to the integration process scenario. As a result, the integration process is no longer fully automated. It is interrupted at a specific point by interaction with the end user, for example to obtain confirmation for a certain procedure. This scenario is shown in the following diagram:
Trigger:
An application places a message in the queue.
Primary flow:
