I've added a jar in the extension folder of my JRE (
lib/ext) in order to provide an extension code to my applications.
Now I want to delete this jar, but I cannot. The error message says:
Cannot delete. It is being used by another person or program
BTW. My Java program is not running at the same time I want to delete the jar.
How can I remove this jar from the
ext directory of the JRE?
