LinuxProgramming: First alpha release of Jython-2.1

“Jython is a Java implementation of the Python programming
language. It allows users to compile Python source code to Java
byte codes, and run the resulting bytecodes on any Java Virtual
Machine. It is a very seamless and smooth integration with Java:
from Python you have complete access to all Java libraries, can
build applets, can integrate with Java beans, and can subclass Java
classes in Python and vice versa. Like Python, and unlike Java,
Jython can also be used interactively: just type some Jython code
at the prompt and see the results immediately.”
