Python bridge for the Java Virtual Machine.

Project description

jvm

Python bridge for the Java Virtual Machine.

Overview

jvm is a bridge between Python and JVM, allowing these to intercommunicate.
It is an effort to allow Python programs full access to Java class libraries.

PyPI record.

Documentation.

jvm package is closely based on the jni Python package.

What is jvm:

jvm is an effort to allow Python programs full access to Java class libraries.
This is achieved not through re-implementing Python, as Jython has done, but rather through interfacing at the native level in both virtual machines.

Eventually, it should be possible to replace Java with python in many, though not all, situations. JSP, Servlets, RMI servers and IDE plugins are good candidates.

Once this integration is achieved, a second phase will be started to separate the Java logic from the Python logic, eventually allowing the bridging technology to be used in other environments, I.E. Ruby, Perl, COM, etc …

Known Bugs/Limitations :
  • Java classes outside of a package (in the <default>) cannot be imported.

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

  • Some methods rely on the “current” class/caller. Since calls coming directly from python code do not have a current class, these methods do not work. The User Manual lists all the known methods like that.

Installation

python -m pip install --upgrade jvm

To ensure everything is running correctly you can run the tests using:
