Jython: Java-Based Python Interpreter Hits Version 2.2

The first stable release of Jython for six years implements version 2.2 of the Python language. The release also includes new features from the Jython developer version 2.1 including new style classes, new import hooks (based on PEP 302), and the integration of Java lists. Other new features include iterators, generators and SSL support. For a comprehensive list of changes and bugfixes, see the changelog.

Jython is an implementation of the Python language that was written completely in Java, whereas the traditional Python interpreter is a C program. Jython compiles Python classes to build Java byte code which can be run on a Java Virtual Machine. Jython thus builds a bridge between the two languages: Python applications can use Java's class libraries, and Java applications can use Python scripting.

The reworked Jython installer is available for downloading as a typical Java Jar archive; the source code is available from the project's CVS.
