Pass return code from Java application to a .bat file.

System.exit(<your return code - as an int - here>);

I tried that, but it doesn't return the value...

In my Java app, I had System.exit(returnCode) and in the '.bat' file

I have
@echo off
java <myApp>
set returnCd=%?%
echo %returnCd

and it didn't return any value. What should I specify in set returnCd=%?% instead of ?

Got it. It should be ERRORLEVEL.
