a C++ code generator for calling Java from C++/Python

Project description

For changes since earlier releases, see:

JCC is a C++ code generator for producing the code necessary to call into Java classes from CPython via Java’s Native Invocation Interface (JNI).

JCC generates C++ wrapper classes that hide all the gory details of JNI access as well Java memory and object reference management.

JCC generates CPython types that make these C++ classes accessible from a Python interpreter. JCC attempts to make these Python types pythonic by detecting iterators and property accessors. Iterators and mappings may also be declared to JCC.

JCC has been built on Python 2.3 to 2.7, on Python 3.6, and has been used with various Java Runtime Environments such as Sun Java 1.5 and 1.6, Apple’s Java 1.5 and 1.6 on Mac OS X, open source Java OpenJDK 1.7 builds as well as Oracle Java 1.7 and 1.8.

JCC is supported on Mac OS X, Linux, Solaris and Windows.

JCC is written in C++ and Python. It uses Java’s reflection API to do its job and needs a Java Runtime Environment to be present to operate.

JCC is built with distutils or setuptools:

python build
sudo python install

Setuptools is required to build JCC on Python 2.3.

JCC’s file needs to be edited before building JCC to specify the location of the Java Runtime Environment’s header files and libraries.

The svn sources for JCC are available at:
