 I was playing with JRuby and wondered how hard it would be to consume
 Clojure from JRuby.

 It turns out that it was not hard at all.

 For anyone interested, I attached a working interface.

Rack talk by Christian Neukirchen   06 Dec 07

We use rack at personifi. Highly recommended simple elegant and fast!

Developing general web frameworks and frameworkless web applications is difficult because lots of different ways to connect to web servers need to be implemented. Since Ruby is popular for writing web applications, we try to address this problem by proposing a lightweight abstraction mapping HTTP requests onto a simple Ruby API. This makes it possible to combine all kinds of web servers with different web applications without further change. Furthermore, our solution enables new functionality by combining and composing web applications, as well as better testability. Talk given at the European Ruby Conference (Euruko) 2007.
