JCC is a code generator for producing a Python extension providing access to a set of Java classes. For every Java class, JCC generates a C++ wrapper class that hides the gory details necessary for accessing methods and fields from C++ via Java's Native Invocation Interface. JCC can also generate C++ wrappers that make it possible to access these classes from Python. When generating Python wrappers, JCC produces a complete Python extension via the distutils package that makes it readily available to the Python interpreter. JCC is a project maintained by the Open Source Applications Foundation.
