ESXX

ESXX, pronounced Essex, is a Web application server that executes Web applications written in JavaScript (AKA ECMAscript) on the server-side. It's written in Java and has no external dependencies except for J2SE 6.0. Everything else that's required is packaged in one single, executable JAR file, ready to be tested in Linux, Mac OS X, Solaris, Windows or any other platform where Java 6 is available.
