Python bridge for the Java Native Interface.

jni

Python bridge for the Java Native Interface.

Overview

jni is a complete bridge between Python and Java JNI.

It is an effort to allow python programs full access to Java JNI API.

PyPI record.

Documentation.

jni is a lightweight Python package, based on the ctypes, or cffi library, or Cython wrapper (currently under development).

It is done by implementing whole JNI API functionality in a clean Python instead of C/C++.

jni also contains a JNI wrapper in pure C based on Python C-API (currently under development) - mainly for performance reasons.

What is jni:

jni is an effort to allow python programs full access to Java JNI API.

This is achieved not through re-implementing Python, as Jython has done, but rather through interfacing at the native level in both virtual machines.

Known Bugs/Limitations :

• Because of lack of JVM support, you cannot shutdown the JVM and then restart it.
