More from the event processing vendors Blogs. This time from SAP. Its ESP product. SAP event processing Blog notifies on a new feature in the product that enables a derived event to trigger WSDL that prompts the user for requesting a predefined web service. In the EPN terminology, this WSDL is an event consumer. There are also other products that cross the borders and provide actions as part of the event processing product. As integration with adjacent systems is a major issue, there are already several solutions which extends event processing to the consumer side, with built-in actions. It is also useful to extend to the producer side -- the instrumentation process. I'll write about the producer side in another post.
