1. A method in a data processing system for integrating components with different interfaces in an enterprise application integration environment, the method comprising: responsive to an attempt to wire a first application component to a second application component, determining whether an interface reference on the first application component does not match an interface of the second application component; and responsive to determining that the interface does not match an interface of the second application component, interposing an interface mediation component between the first and second application components to enable wiring of the first application component to the second application component, wherein the interface mediation component comprises an interface matching the interface reference on the first application component and an interface reference matching the interface on the second application component, and wherein the interface mediation component binds a first operation in the first application component to a second operation in the second application component and performs a parameter mediation of parameters in the first operation to parameters in the second operation.
