Question

How to limit the validity days for executable jar file?

Answer 1

First of all a .jar file isn't executable. It's basically a .zip file containing the .class files in a specific directory structure. If you want to limit how long the application will be valid for, you will need to code some system into the application you're bundling as a .jar. This system will need to be able to accurately determine how long the application has been in use.

Basically, there is no quick short cut specific to .jar files.
