Java Runtime execution not working in cron job @reboot showing error "Unable to connect to X server"

I have a bash script to be executed using a jar file, Im using the Runtime method as given below:

`Process proc = Runtime.getRuntime().exec("bash /location/to/");`

The script executes well when the jar file is run from the terminal but when It comes to cron (sudo) it’s not executing the Script.

I tried logging the process.ErrorStream(); and got an error “unable to connect to X server”.

I tried using ProcessBuilder in java but it’s still not working.

I tried How to Autorun Application at the Start up in Linux (
section GRAPHICS, but It’s not coming out from the # wait for weston loop.
I’m a newbie… can someone help to come out from this issue?
