Dynamic invocation of web services
First Claim
1. A system for dynamically invoking an operation in a remote instance of a Web service, the system comprising:
- a set of port selection rules for selecting one of a set of ports through which a remote instance of a Web service can be invoked;
a Web services container configured to service requests for Web services by invoking remote instances of said requested Web services;
a port resolution processor disposed within said Web services container, said port resolution processor having a configuration for dynamically selecting, according to said port selection rules, an individual port from among said set of ports through which said Web services container can invoke said remote instances of said requested Web services; and
a Web service discovery processor able to query a remote registry of Web services to identify sets of Web service implementations accessible by a preferred communication protocol.

Abstract
A method for dynamically invoking a Web service. The method can include assembling a collection of references to remote implementations of the Web service based upon a common port type. One or more ports bound to the remote implementations of the Web service can be identified, and a set of port selection rules can be applied to the identified ports to select a particular one of the ports. Finally, the Web service can be invoked through the selected port. Notably, the identifying step can include parsing a Web service implementation document for each referenced remote implementation in the collection. The parsing can produce a list of ports through which the remote implementations can be invoked. Also, the method can further include compiling the set of port selection rules according to at least one of high-availability concerns, quality of service concerns and economic concerns.

5. A method for dynamically invoking a Web service comprising the steps of:
-
assembling a collection of references to remote implementations of the Web service based upon a common port type; identifying a plurality of ports bound to said remote implementations of the Web service;
applying a set of port selection rules to said identified ports to select a particular one of said ports; and
