Techniques for extending a Web services system are provided. One or more Web service applications (WSA) execute on a device. Each WSA provides at least one service. A WSA implements a particular version of a Web Services (WS) specification that is previous to a current version of the WS specification. In one technique, an orchestration module is added that coordinates the interaction between the WSA and one or more extension modules. While processing the request, the WSA calls the orchestration module. The orchestration module, based on one or more attributes of a request, determines whether an extension module, that comprises logic, should be called to process a portion of the request. The logic corresponds to a difference between the previous version and the current version. After an extension module finishes processing the portion of the request, the WSA is caused to further process the request.
