Usage of Py4J

[Evelyn]

Hello, 

I am very unfamiliar with Java, but comfortable with CPython. I have several C-based Python scripts, with several dependencies each, which need to be used with a piece of software that only interprets Java-based Python (Jython) and not CPython. Obviously, re-writing these scripts would take years. Is Py4J something could aid in this project?

Hi Evelyn,

At a high level I would say that yes Py4J would do the trick. Py4J makes it relatively easy to interoperate between a CPython and Java process and do remote calls (RPC) between them, especially if there is a Java API you are trying to access from Python. 

However, if you don't have the source for the Java side and the Java side doesn't have a published API, this may be difficult. 

Are you looking to run Jython scripts, or access other things on the Java side?
