<P>PROBLEM TO BE SOLVED: To provide a technology for updating software components on a multi-function peripheral (MFP) of a Web Services (WS). <P>SOLUTION: The MFP sends a multi-cast discovery message that conforms to a WS-Discovery protocol. An update server receives the discovery message and responds with a discovery response message that also conforms to a WS-Discovery protocol. The MFP sends to the update server an event subscription message that conforms to a WS-Eventing protocol. The event subscription message indicates one or more software components for which the MFP seeks an update. When update of a subscribed-for software component is available, the update server sends to the MFP an event notification message that conforms to the WS-Eventing protocol. In response to a message that requests the updated component, the update server sends to the MFP the updated software component. <P>COPYRIGHT: (C)2010,JPO&INPIT |
