If you do any Java programming you can use the JT400 remote command call

Wouldn't Java and JT400 be a roundabout way of calling an IBM i program
from another? Wouldn't you be lengthening the call path significantly? What
value would the middleware bring to the table?

Richard has already responded, but I have my own reading of that comment:

Notice that he first includes the qualifier "if you do any Java
programming". So, from where I'm sitting, at least a good chunk of the
value of JT400 is that *for a certain audience*, it's going to be an
easy-to-implement solution.

It's always easiest to use what you know. I often marvel at the hoops
RPG programmers jump through to accomplish things that *I* find vastly
easier in Python. But if you already know RPG but not Python, and
especially if you have good RPG tooling and what I call "RPG
infrastructure", then it may well be easier for you to write 1000
lines of RPG rather than 30 lines of Python.

I don't dispute that the "call path" may be much longer for some
approaches than others. But depending on the application, that might
not matter very much.
