JavaSpaces

JavaSpaces

An application that provides a unified environment for sharing, communicating and coordinating within a Jini network. It functions like a virtual bulletin board, enabling information to be posted and responded to by the appropriate (object-based) application. For example, sellers could post items for sale, and buyers could respond. See Jini.
