Set up java environment variable value using bat command permanently

Question

I write a bat script to set java path in envirnment variable. I use following command to set path -

setx PATH=%jdkDirDest%\bin;%PATH%.
setx PATH=%playDirDest%;%PATH%.
set PATH=%jdkDirDest%\bin;%PATH%.
set PATH=%playDirDest%;%PATH%.

It works fine when I am working with current session But what happen if I closed current command prompt and again open and run following command

java -version
javac etc.

It shows no java version is intall in this system

Can any one sugest me what code I use to set these environment path permanently to my matchine using bat command.

** I need bat command.

You have to use setx without the '=', and set with it. Also use quotes for the values of the environment variables

setx PATH "%jdkDirDest%\bin;%PATH%"
setx PATH "%playDirDest%;%PATH%"
