What is Jython?

     Jython, lest you do not know of it, is the most compelling weapon 
the Java platform has for its survival into the 21st century:-)

     —Sean McGrath, CTO, Propylon

Jython is an implementation of the high-level, dynamic, object-oriented 
language Python seamlessly integrated with the Java platform. The 
predecessor to Jython, JPython, is certified as 100% Pure Java. Jython 
is freely available for both commercial and non-commercial use and is 
distributed with source code. Jython is complementary to Java and is 
especially suited for the following tasks:

     * Embedded scripting - Java programmers can add the Jython 
libraries to their system to allow end users to write simple or 
complicated scripts that add functionality to the application.
     * Interactive experimentation - Jython provides an interactive 
interpreter that can be used to interact with Java packages or with 
running Java applications. This allows programmers to experiment and 
debug any Java system using Jython.
     * Rapid application development - Python programs are typically 
2-10X shorter than the equivalent Java program. This translates directly 
to increased programmer productivity. The seamless interaction between 
Python and Java allows developers to freely mix the two languages both 
during development and in shipping products.

There are numerous alternative languages implemented for the Java VM. 
The following features help to separate Jython from the rest:

     * Dynamic compilation to Java bytecodes - leads to highest possible 
performance without sacrificing interactivity.
     * Ability to extend existing Java classes in Jython - allows 
effective use of abstract classes.
     * Optional static compilation - allows creation of applets, 
servlets, beans, ...
     * Bean Properties - make use of Java packages much easier.
     * Python Language - combines remarkable power with very clear 
syntax. It also supports a full object-oriented programming model which 
makes it a natural fit for Java's OO design.
