Understanding COM Connector Guaranteed Events

The COM connector events solution uses the Microsoft COM+ Events Service. COM+ Events Loosely Coupled Events, which matches and connects publishers and subscribers, is part of the Microsoft Windows Component Services. The EventClass is a COM+ component that contains interfaces and methods that are used by the publisher to initiate events. The EventClass manages the connection between publisher and subscribers. The EventClass.dll, which contains the IOWEvent interface, is provided. The COM servers and COM clients must implement this interface so that when an event is initiated, this interface is called by the COM+ Events Service and the implementation is executed. The implementation decides what the delivered event and the event data should do. This implementation is COM server or COM client specific.

To support guaranteed event delivery for JD Edwards EnterpriseOne, the COM connector uses XML. This illustration shows the COM connector architecture for guaranteed events:

Note: You should have a basic understanding of the COM+ Events Service.COM+ events supports Z events, real-time events, and XAPI events. COM+ Events Service is not dependent on JD Edwards EnterpriseOne setup for event generation.
