Abstract: Certain example embodiments concern a gateway server system including a gateway server for making at least one SOAP and/or XML-based web service accessible to at least one RPC client using at least one mapping file. The at least one mapping file includes definitions for translating at least one first RPC request message from the at least one RPC client to at least one web service call. The gateway server includes a configuration interface to receive and store the at least one mapping file. The gateway server is configured to create at least one first sub-program for processing the at least one first RPC request message in accordance with the at least one mapping file. The configuration interface is further configured to receive at least one updated mapping file and overwrite the corresponding at least one stored original mapping file, without affecting the processing of the at least one first subprogram.

Abstract: The present invention concerns a gateway server system comprising a gateway server (1) for making at least one SOAP/XML-based web service (2) accessible to at least one RPC client (3) in accordance with at least one mapping file (10), the at least one mapping file (10) comprising definitions for translating at least one first RPC request message (30) from the at least one RPC client (3) to at least one web service call (20) of the at least one SOAP/XML-based web service (2), the gate-way server (1) comprising: a. a configuration interface (4) adapted for receiving and for storing the at least one mapping file (10) in a storage medium (6); b. wherein the gateway server (1) is adapted for creating at least one first sub-program (60) adapted for processing the at least one first RPC request message (30) in accordance with the at least one mapping file (10); and c.
