I have downloaded a .jar file and I run it with openJDK.
But Ubuntu says "The file '/home/mahdi/Downloads/something.jar' is not marked as executable. If this was downloaded or copied form an untrusted source, it may be dangerous to run. For more details, read about the executable bit."
I just wanna run it. Any help?
