C++ code generator of wrappers for Java libraries

JCC is a C++ code generator that produces a C++ object interface wrapping a Java library via Java's Native Interface (JNI). JCC also generates C++ wrappers that conform to Python's C type system making the instances of Java classes directly available to a Python interpreter.

When generating Python wrappers, JCC produces a complete Python extension module via the distutils or setuptools packages.
