- ring-servlet - construct Java servlets from Ring handlers
- ring-jetty-adapter - a Ring adapter that uses the Jetty webserver
To include one of the above libraries, for example
the following to your

This project borrows heavily from Ruby's Rack and Python's WSGI;
thanks to those communities for their work.
