Tools for scripting Java using Python

This page lists tools for Java/Python interoperatbility.

The purpose of this page is to provide:

Project status is categorized as


Active Projects


[http://jepp.sourceforge.net/ Jepp] embeds CPython in Java. It is safe to use in a heavily threaded environment, it is quite fast and its stability is a main feature and goal.

[http://jpype.sourceforge.net/ JPype] is an effort to allow python programs full access to java class libraries. This is achieved not through re-implementing Python, as Jython/JPython has done, but rather through interfacing at the native level in both Virtual Machines.


Inactive Projects


[http://www.jython.org/Project/index.html Jython] (formerly: JPython) is a Python-to-Java bytecode compiler. It is written in Java. Most Python scripts should run with little or no modification on Jython. The exception is scripts that use Python extensions written in C. Some modules in the standard library may not be available in Jython.


Discontinued Projects


[http://jpe.sourceforge.net/ JPE] (Java-Python Extension) uses JNI to provide a bridging mechanism between Java and a Python interpreter (including use of C extensions for Python).

[http://www.ndim.edrc.cmu.edu/dougc/jpi/Home.html JPI] was a two-way Python-Java Interface.
