+ +*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](http://code.google.com/p/python-javaobj/) and now hosted on +[GitHub](https://github.com/vbuell/python-javaobj). + +This fork intends to work both on Python 2.7 and Python 3.4+. + +## Compatibility Warnings + +### New implementation of the parser + +| Implementations | Version | +|-----------------|----------| +| `v1`, `v2` | `0.4.0+` | + +Since version 0.4.0, two implementations of the parser are available: + +* `v1`: the *classic* implementation of `javaobj`, with a work in progress + implementation of a writer. +* `v2`: the *new* implementation, which is a port of the Java project + [`jdeserialize`](https://github.com/frohoff/jdeserialize/), + with support of the object transformer (with a new API) and of the `numpy` + arrays loading. + +You can use the `v1` parser to ensure that the behaviour of your scripts +doesn't change and to keep the ability to write down files. + +You can use the `v2` parser for new developments +*which won't require marshalling* and as a *fallback* if the `v1` +fails to parse a file. + +### Object transformers V1 + +| Implementations | Version | +|-----------------|----------| +| `v1` | `0.2.0+` | + +As of version 0.2.0, the notion of *object transformer* from the original +project as been replaced by an *object creator*.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. + +### Object transformers V2 + +| Implementations | Version | +|-----------------|----------| +| `v2` | `0.4.0+` | + +The `v2` implementation provides a new API for the object transformers. +Please look at the *Usage (V2)* section in this file. + +### Bytes arrays + +| Implementations | Version | +|-----------------|----------| +| `v1` | `0.2.3+` | + +As of version 0.2.3, bytes arrays are loaded as a `bytes` object instead of +an array of integers. + +### Custom Transformer + +| Implementations | Version | +|-----------------|----------| +| `v2` | `0.4.1+` | + +A new transformer API has been proposed to handle objects written with a custom +Java writer. +You can find a sample usage in the *Custom Transformer* section in this file. + +## Features + +* Java object instance un-marshalling +* Java classes un-marshalling +* Primitive values un-marshalling +* Automatic conversion of Java Collections to python ones + (`HashMap` => `dict`, `ArrayList` => `list`, etc.) +* Basic marshalling of simple Java objects (`v1` implementation only) + +## Requirements + +* Python >= 2.7 or Python >= 3.4 +* `enum34` and `typing` when using Python <= 3.4 (installable with `pip`) +* Maven 2+ (for building test data of serialized objects. + You can skip it if you do not plan to run `tests.py`) + +## Usage (V1 implementation) + +Un-marshalling of Java serialised object: + +```python +import javaobj + +with open("obj5.ser", "rb") as fd: + jobj = fd.read() + +pobj = javaobj.loads(jobj) +print(pobj) +``` + +Or, you can use `JavaObjectUnmarshaller` object directly: + +```python +import javaobj + +with open("objCollections.ser", "rb") as fd: + marshaller = javaobj.JavaObjectUnmarshaller(fd) + pobj = marshaller.readObject() + + print(pobj.value, "should be", 17) + print(pobj.next, "should be", True) + + pobj = marshaller.readObject() +``` + +**Note:** The objects and methods provided by `javaobj` module are shortcuts +to the `javaobj.v1` package, for Compatibility purpose. +It is **recommended** to explicitly import methods and classes from the `v1` +(or `v2`) package when writing new code, in order to be sure that your code +won't need import updates in the future. + + +## Usage (V2 implementation) + +The following methods are provided by the `javaobj.v2` package: + +* `load(fd, *transformers, use_numpy_arrays=False)`: + Parses the content of the given file descriptor, opened in binary mode (`rb`). + The method accepts a list of custom object transformers.

From c1b54d1161ecbf4b911678ad311a2b3018349454 Mon Sep 17 00:00:00 2001 From: Thomas Calmant Date: Wed, 12 Aug 2026 00:35:26 +0200 Subject: [PATCH 190/200] Switched to setuptools for a universal wheel, added publish.yml javaobj still supports Python 2.7 (v1/v2), so this release ships a single py2.py3-none-any wheel instead of one that only pip on 3.x can even select. hatchling has no equivalent of setuptools' universal flag, so the build backend moved there (setup.cfg's old [bdist_wheel] flag now lives in pyproject.toml's [tool.distutils.bdist_wheel], and setup.py gained the dual-path pattern jsonrpclib uses: pyproject.toml on Python 3, explicit metadata parsed from javaobj/__init__.py on 2.7, whose setuptools can't read [project]). Verified locally with podman, not through the new workflow: python -m build under Python 3.14 produces the py2.py3-none-any wheel and passes twine check --strict; a fresh Python 2.7 container installs correctly both from source (setup.py install) and from that exact wheel, with javaobj.__version__ resolving to 0.6.0 from outside the source tree either way. Along the way, setuptools>=77 rejected the old License classifier now that a SPDX license expression is set (fixed), and check_version.py caught javaobj/v2/main.py missing its version docstring entirely (fixed). Added check_version.py, release_notes.py and sbom_artifacts.py (ported from jsonrpclib, which released a universal wheel the same way), docs/changelog.md as the source of truth for release notes, and publish.yml itself: build, SLSA provenance attestation, CycloneDX SBOM, PyPI Trusted Publishing, GitHub release. Not exercised for real: no tag pushed, no workflow_dispatch run. The PyPI trusted publisher and the pypi/testpypi GitHub environments still need to be configured before a real release can go through.

From f3e0bac7d25df2781daecef522a2bec1ef7f85c8 Mon Sep 17 00:00:00 2001 From: Thomas Calmant Date: Wed, 12 Aug 2026 16:15:23 +0200 Subject: [PATCH 194/200] Fixed the reading of LinkedHashMap in v1 and v3 The entries of a LinkedHashMap are written in the block data of the HashMap it extends, which the unmarshaller already stores in the annotations. v1 read that block data a second time and desynchronized the stream, v3 looked for the entries under the LinkedHashMap level and always returned an empty map. Fixes #30.
