Re: [Jython-users] How to interact with jython program from C++

[<jem...@fr...>]

To invoke your Jython program from C++ you have two options:

1)  Easy -  Invoke jython as a separater process: for example,
system("jython yourpythoncode.py inputfilename outputfilename");
2)  Hard - Use JNI to embed a Java runtime in your C++ program,
instantiate the runtime, tell it to execute the Jython interpreter with
your files.
