Nirvana and Matrix

Nirvana is a Java based message oriented middleware package supporting the publish subscribe model. It supports message persistence and XML DOM Documents as well as straight TCP communications and HTTP/HTTPS tunneling. Nirvana supports a federated namespace and instances can be joined together. Matrix is a connector framework providing "out of the box" connectors for most commonly used middleware products. Matrix supports a "many 2 many" configuration in a single instance and allows the user to define transactions that define relationships between source and destination systems.
