A method, system and product is provided for the implementation of business to business event handling mechanisms for use in coarse grain components allowing communication of event information among providers and interested subscribers across a network. Provision of a flexible method for resolution of business event model dependencies allows a business component to define its own business event model independently and further may also allow changes to that model. This provision may be used to allow a client without an event handling server to place a dependency on another business component for the provision of event handling services. Further, using a web services architecture network implementation for communications, provides the capability of a business event handling system as a web service.
