POJ - Equinox (jini.org)

Equinox (equinox.jini.org) is a new project to develop a Jini-based container for the Spring framework.
The Spring framework, originally targeted at JEE applications, can dramatically simplify code and improve component design by "keeping the container out of the code".
Applications that use Spring can eliminate explicit dependencies on the JEE container and typical JEE boilerplate code, introducing a new dimension of portability.
The Equinox container will host new and existing Spring-based applications in a dynamic Jini environment.
The container implementation will transparently leverage Jini's service discovery, transaction management and fault tolerance, and will facilitate the application's use of characteristic features like JavaSpaces.
