Abstract: Methods, systems, and products are disclosed in which port type agnostic proxy support for web services intermediaries is typically provided by receiving in a web services intermediary a request for execution of a web services operation, wherein the request includes parametric information from which an endpoint for a target service that supports the operation can be identified; identifying, in dependence upon the parametric data, the endpoint for a target service that supports the operation; creating a target service request for execution of the operation on the target service; and issuing the target service request to the target service. Exemplary embodiments typically also include the return path of request-response processing: receiving in the intermediary a response from the target service; creating in the intermediary, in dependence upon the response from the target service, a response from the intermediary; and returning the response from the intermediary to the requesting client.
