I need to programmatically edit, write or delete protected files. In Windows, if i do it manually, it asks for permission and in Unix systems i need “sudo”.
How can I ask in Java for higher privileges during execution?
If your program requires high level access it is best to advise the user that they need to run it as root / a privileged account in order to work.
Otherwise the best option is to start a new ‘proxy process’ that is initialised using “sudo” and then a program doing what you want, eg “sudo cp File1 File2” that will perform your dirty work for you.
Unfortunately this is not cross platform and requires the users password.
There is simply no way you can just bump the JVM to a higher user during execution as this would pose a huge security risk.
