What is the easiest way to call a Julia function from Java? And if such possibility is not straightforward, will it be implemented in further versions of Julia (or maybe this requires a new library for Java)? I feel that such a popular language as Java deserves some kind of interface to Julia.

From [this comment on the old mailing list](https://groups.google.com/forum/#!topic/julia-users/uutK5viQMjw) it looks like the easiest option would be to use JNI to interact with Julia via its C API, combined with [JavaCall.jl](https://github.com/JuliaInterop/JavaCall.jl) on the Julia side to handle the conversions (this is roughly analogous to how pyjulia works, using PyCall.jl on the Julia side).

As I mentioned on [another thread](https://discourse.julialang.org/t/julia-and-python-conda/18339/3):

> Unfortunately, bindings _from_ external languages aren’t the most popular thing for people to voluntarily work on, since “people who like to write Julia code” don’t directly benefit themselves from that work

Hi I am trying to run the julia scripts using simple java service. Since it’s been 2 years, any update on how can we achieve this ?
