Title: What is Jython?
<h3>What is Jython?</h3>
<P>Jython is an implementation of the high-level, dynamic,
object-oriented language <A HREF="http://www.python.org">Python</A>
seamlessly integrated with the
<A HREF="http://www.javasoft.com">Java</A> platform.
The predecessor to Jython, JPython, is certified as
<A HREF="http://www.javasoft.com/100percent/">100% Pure Java</A>.
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:</P>
<UL>
<LI><B>Embedded scripting</B> - 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.
<LI><B>Interactive experimentation</B> - 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.
<LI><B>Rapid application development</B> - 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.
</UL>
<P>There are numerous
<A HREF="http://grunge.cs.tu-berlin.de/~tolk/vmlanguages.html">
alternative languages</A>
implemented for the Java VM. The following features help to separate
Jython from the rest:</P>
<UL>
<LI><B>Dynamic compilation to Java bytecodes</B> - leads to
highest possible performance without sacrificing interactivity.
<LI><B>Ability to extend existing Java classes in Jython</B> -
allows effective use of abstract classes.
<LI><B>Optional static compilation</B> - allows creation of
applets, servlets, beans, ...
<LI><B>Bean Properties</B> - make use of Java packages much easier.
<LI><B><A HREF="http://www.python.org/doc/Summary.html">
Python Language</A></B> - 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.
