PUBLIC MARKS with tags jython & javascript

When I wrote Java, Groovy and (J)Ruby, Owen Densmore and Lawrence Oluyede suggested that I should include Jython as well. Here it is.... JavaScript and Jython for Java programmers. Note that while I am reasonably comfortable with Java and JavaScript, I don't know much about Jython. If you find anything wrong here, please let me know. I used Jython version 2.1. For JavaScript, I used Rhino 1.6R2 that is co-bundled with JDK 6. The jsr-223 script engine for Jython and many other languages are avaiable at http://scripting.dev.java.net
