How to run sudo command without password from java program? [duplicate]

Answer 1

Grant your user the permissions by using sudo. Have a look here: http://www.ducea.com/2006/06/18/linux-tips-password-usage-in-sudo-passwd-nopasswd/

For example:

/etc/sudoers
admin    ALL = NOPASSWD: ALL

Answer 2

If you can get it to run that would mean a security flaw.

Said so...

1. Grant your user permissions (become sudoer)

2. Invoke your java program with sudo

   $ sudo java JavaCommandProg

This will prompt you for introducing sudo password when running jvm and then you can invoke sudo from inside your Java program.
