I have a jar which is deployed and then executed on some machine. When the process ends, I would like to delete that jar automatically. What is a best way to do so? Can a jar delete itself when the process exits?

Couldn't you just find the directory of the jar internally, then delete it? Possibly inside a finalize method. – Carcigenicate Jun 29 '15 at 19:00

but how can finalize method delete a jar which contains that finalize method? – Tad Jun 29 '15 at 19:44

Also, there are hundreds of jars uploaded there so I can't just get the directory. the process is: jar gets uploaded, executed, then i want it to be deleted – Tad Jun 29 '15 at 19:45

I've never done it in Java, but there should be a way to get the path to the current process. And wouldn't the jar be for the most part in the RAM by that point? You may get a error saying that the resource is in use, but I'm sure there's a way around that. – Carcigenicate Jun 29 '15 at 19:48

http://stackoverflow.com/questions/28418807/how-to-delete-the-executable-jar-file-by-it-self Looks like on Windows, a jar can't be deleted of it's currently being used by the JVM. You could have a separate clean up program that feels with this. – Carcigenicate Jun 29 '15 at 19:54
