In my company some data science components are written using Python scripts. But our web application is Java. Now, I need to call these Python scripts from my web application supplying some data and run time parameters. What is the best way to make such calls.

Our data scientists are thinking of opening their Python APIs as ZeroRPC based endpoints and expect me to write a Java client to call their APIs. (I Googled and there is not a lot of information on this). Is this the right way? What are the typical/standard ways to interact with Python code?

unusual question ... (for a ZK forum) I guess the simplest way would be to execute a new process and consume the output stream

https://docs.oracle.com/javase/8/docs/api/java/lang/ProcessBuilder.html


as for remote calls (RPC) it depends on the protocol used, if you find a Java api to call zerorpc

I found this 5 year old implementation: https://github.com/jamescarr/zerorpc-java

the code for the client implementation doesn't look complicated and easy to reuse:

https://github.com/jamescarr/zerorpc-java/blob/master/src/main/java/org/zerorpc/ZeroRPCClient.java

I haven't tried this but it looks like it's based on 2 other libraries jeromq and msgpack (which still seem active up to today)
