You don't embed JREs into jar files. The JRE should be installed on the client machines.
It's the one that runs the jar file so if it's not there the .jar will not run.

if the client user has no java installed in the computer then do i had to install jre or the whole jdk as we usually done.

The client will only need the JRE for running the program.
The JDK is for development.
You could create a launcher program for the target OS that detects if Java is installed and asks the user to install Java if they don't have it or just launch your Jar file if Java is detected.
