ActiveCluster

ActiveCluster is a framework for writing cluster-based applications, monitoring the available nodes in a cluster and communicating with them. ActiveCluster consists of an API together with a default implementation.

The API is simple and small which reuses a few of the standard JMS APIs for Message, Destination, MessageListener and adds a few simple interfaces for working with clusters representing nodes in the cluster, replicated node state and listeners to nodes joining, leaving or updating their state.
