The SprintStack project marries the elegance of node.js with the power of the JVM.
$ git clone git://github.com/sprintstack/sprintstack.git $ cd sprintstack $ ant $ ./bin/sprintstack $ > console.log("Hello, SprintStack!");
Check out the wiki for more information on how to get up & running.
SprintStack gives developers a node-compatible environment with all the benefits of the JVM, such as idiomatic support for concurrency, solid garbage-collection and a huge range of existing libraries.
If you want your node.js applications to take advantage of a fast, mature VM and the state-of-the-art in fault-tolerant & distributed programming then give SprintStack a try!
