Changing running permission to Root

Hi

I want to write a simpe Java application that has a Root permission (like modifying the /etc/hosts file).

I want to run this application with a X user that that user will have abilities to modify the /etc/hosts file.

Is it possible to do that in Java ?

I know that in C,C++ I can do that.

Thanks,

Liron

I didn't followed you.
Let's say that I have a application called: My.class
This application needs to execute the command "mv /etc/hosts /etc/hosts.sav"

I'm running this application under user: lirong.

In order to execute the move, I need to execute it in a root permission.
How do I do that ?
