Hi folks, Due to the discussion in Running Julia from Java - What is crazier? , I am introducing a new project for calling Julia from within Java. Despite it is in its early stages, the package implements basic external calling of Julia from Java and a skeleton of JSR 223 (Java scripting interface) …

Hi, I’ve been digging into JuliaCaller a bit as I am comparing the various Julia-from-Java solutions out there and had a quick question: what made you go for tcp/json as opposed to “basic” process to process communication?

I wanted to try what I did in the RCaller project which is library for calling R from within Java using the s…

Hi , Thanks for the reply I mean I have a multiple .jl files that needs to be executed using java How can I achieve that ?
