A python module for unpacking and inspecting Java Class files, JARs, and collections of either.

It can do deep checking of classes to perform comparisons of functionality, and output reports in multiple formats.

• python-javatools on GitHub
• python-javatools on PyPI

If you have suggestions, please use the issue tracker on github. Or heck, just fork it!

• Python 2.6 or later (now with Python 3 support!)
• Setuptools
• M2Crypto is used for cryptographic operations

In addition, the following tools are used in building and testing the project.

• GNU Make
• Pylint

All of these packages are available in most linux distributions (eg. Fedora), and for OSX via MacPorts.

This module uses setuptools, so running the following will build the project:

python setup.py build

to install, run:

sudo python setup.py install

Tests are written as unittest test cases. If you'd like to run the tests, simply invoke:

python setup.py test

There is also a custom pylint command, which can be use via:

python setup.py pylint

If you'd prefer to build an RPM, see the wiki entry for Building as an RPM.

• classinfo - similar to the javap utility included with most JVMs. Also does provides/requires tracking.

• classdiff - attempts to find differences between two Java class files

• jarinfo - prints information about a JAR. Also does provides/requires tracking.

• jardiff - prints the deltas between the contents of a JAR, and runs classdiff on differing Java class files contained in the JARs

• jarutil - creates JAR, signs JAR, verifies JAR signature

• manifest - creates and queries JAR manifests

• distinfo - prints information about a mixed multi-jar/class distribution, such as provides/requires lists.

• distdiff - attempts to find differences between two distributions, deep-checking any JARs or Java class files found in either directory.

• Oracle's Java Virtual Machine Specification Chapter 4 "The class File Format"
• Java Archive (JAR) Files
