This paper presents the design and implementation of an application program an error sharing agent for collaborative multimedia distance education system which is running on RCSM (Reconfigurable Context Sensitive Middleware) for ubiquitous networks. RCSM provides standardized communication protocols to interoperate an application with others under dynamically changing situations. It describes a hybrid software architecture that is running on situationaware middleware for a web based distance education system which has an object with a various information for each session and it also supports multicasting with this information.
