Project Description

python-javaobj is a python library that provides functions for reading and writing (writing is WIP currently) Java objects serialized or will be deserialized by ObjectOutputStream. This form of object representation is a standard data interchange format in Java world.

The javaobj module exposes an API familiar to users of the standard library marshal, pickle and json modules.

About this repository

This project is a fork of python-javaobj by Volodymyr Buell, originally from Google Code and now hosted on GitHub.

This fork intends to work both on Python 2.7 and Python 3.2+.

Compatibility Warning: object transformer

As of version 0.2.0, the notion of object transformer from the original project as been replaced by an object creator.

The object creator is called before the deserialization. This allows to store the reference of the converted object before deserializing it, and avoids a mismatch between the referenced object and the transformed one.

Compatibility Warning: bytes arrays

As of version 0.2.3, bytes arrays are loaded as a bytes object instead of an array of integers.

Features

  • Java object instance unmarshaling
  • Java classes unmarshaling
  • Primitive values unmarshaling
  • Automatic conversion of Java Collections to python ones (HashMap => dict, ArrayList => list, etc.)
  • Basic marshalling of simple Java objects

Requirements

  • Python >= 2.7 or Python >= 3.2
  • Maven 2+ (for building test data of serialized objects. You can skip it if you do not plan to run tests.py)

Usage

Unmarshalling of Java serialised object:

import javaobj

jobj = self.read_file("obj5.ser")
pobj = javaobj.loads(jobj)
print(pobj)

Or, you can use Unmarshaller object directly:

import javaobj

marshaller = javaobj.JavaObjectUnmarshaller(open("objCollections.ser"))
pobj = marshaller.readObject()

self.assertEqual(pobj.value, 17)
self.assertTrue(pobj.next)

pobj = marshaller.readObject()
