Rack port to Java?

Do you know i开发者_JS百科f Rack was ported to Java? To be more specific, I am aware of jruby-rack but I am looking for a native Java (re)implementation of Rack, if any?!

Thank you in advance, - florin

I came across JRack at some point, though I don't really know anything about it.

Here's a blog post about JRack: http://blog.approvaltests.com/2009/09/hello-jrack.html

Looks like it's been at version 0.0.001 since September 09, so use at your own risk.
