JavaSpaces is a service specification. It provides a distributed persistence and object exchange mechanism for Java objects. It can be used to store the system state and implement distributed algorithms. In a JavaSpace all communication partners (peers) communicate by sharing state. It is an implementation of the Tuple spaces idea.
JavaSpaces is used when someone wants to achieve scalability and availabilty and at the same time reducing the complexity of the overall system.
JavaSpaces technology is descended from the Java Jini technology, which has not been a commercial success. However some vendors are now (2004) offering JavaSpaces-based products as a way to provide distributed reliable persistence for non-Jini environments.
