Claim 11

A server application for use in a computer system, the computer system including at least one processor executing said server application and at least one client application, the server application comprising: an execution unit; an input unit operatively coupled to said execution unit and said server application; and an output unit operatively coupled to said execution unit and said server application; wherein said execution unit executes a plurality of operations, each operation of said plurality of operations being identified by at least one operation identifier of a plurality of operation identifiers, each operation identifier of said plurality of operation identifiers identifying one or more operations of said plurality of operations; wherein said input unit receives a first request from said at least one client application, said first request requesting said server application to perform a selected operation of said plurality of operations, said first request identifying said selected operation by a first operation identifier, wherein said first operation identifier is one of said plurality of operation identifiers, wherein said first operation identifier identifies said selected operation; wherein said execution unit executes said selected operation when said first operation identifier identifies only said selected operation; and wherein said output unit transmits a notification to said at least one client application notifying said at least one client application that said first operation identifier was ambiguous and that said selected operation was not performed when said first operation identifier identifies more than one operation of said plurality of operations.

Claim 12

A server application for use in a computer system, the computer system including at least one processor executing said server application and at least one client application, the server application comprising: an execution unit; an input unit operatively coupled to said execution unit and said server application; and an output unit operatively coupled to said execution unit and said server application; wherein said execution unit executes a plurality of operations, each operation of said plurality of operations being identified by at least one operation identifier of a plurality of operation identifiers, each operation identifier of said plurality of operation identifiers identifying one or more operations of said plurality of operations; wherein said input unit receives a first request from said at least one client application, said first request requesting said server application to perform a selected operation of said plurality of operations, said first request identifying said selected operation by a first operation identifier, wherein said first operation identifier is one of said plurality of operation identifiers, wherein said first operation identifier identifies said selected operation; wherein said execution unit executes said selected operation when said first operation identifier identifies only said selected operation; and wherein said output unit transmits a notification to said at least one client application notifying said at least one client application that said first operation identifier was ambiguous and that said selected operation was not performed when said first operation identifier identifies more than one operation of said plurality of operations.

Claim 13

The server application of claim 10 wherein said input unit receives a second request from said at least one client application for said server application to perform said selected operation when said client application receives said notification from said server application, said selected operation being identified by a second operation identifier in said second request, wherein said second operation identifier is one of said plurality of operation identifiers, wherein said second operational identifier identifies said selected operation, said second operation identifier being a different operation identifier than said first operation identifier.

Claim 14

The server application of claim 11 wherein said plurality of operation identifiers include a plurality of short operation identifiers and a plurality of long operation identifiers, each operation of said plurality of operations being identified by a short operation identifier from said plurality of short operation identifiers, each operation of said plurality of operations further being identified by a long operation identifier from said plurality of long operation identifiers, wherein, for each operation of said plurality of operations, the short operation identifier that identifies the operation is shorter than the long operation identifier that identifies the operation.
