JavaSpaces

JavaSpaces is a service specification from Sun Microsystems that provides a simple yet powerful infrastructure for building distributed applications. The JavaSpaces specification defines a reliable distributed repository for objects, along with support for distributed transactions, events and leasing. In the JavaSpaces programming model, applications are viewed as a group of processes, cooperating via the flow of objects into and out of spaces.

The JavaSpaces API provides software developers with a simple and effective tool for solving coordination problems in distributed systems, especially in domains like parallel processing and distributed persistence. The developer designs the solution as a flow of objects instead of a traditional request/reply message-based scenario.
