Install process app with command line tools - how?

I have jBPM v7 full installation.
I have .jar with the process app inside.
I successfully deploy it via KIE Workbench (upload artifact, then deploy it on kie server and start it).
Now I want to do the same from linux console.
I tried jboss-cli - no luck. I can't find which node should I use do make the app running.
I tried to dig in the workbench rest API (in hope to use curl later) - no luck at all. I failed even to get any rest service called - 404 all the time.

So the question is - how to install the app .jar on jBPM without using web UI of the workbench?
