如何在 Java 中以 root 权限运行 shell 命令

我需要以 root 权限在 Java 中运行 shell 命令（在我的例子中是 ipfw）。我使用 ProcessBuilder 来运行没有特权的命令：

Process p = new ProcessBuilder("ls","/").start();

BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream()));

String s;
while((s=br.readLine()) != null) {
    System.out.println(s);
}

此代码工作正常，但我需要运行类似 sudo 的东西 root 命令。我该怎么办？

我需要在 Eclipse、Mac OS X 10.6.8 中运行这个程序

编辑：现在我从终端使用 sudo java nameclass 但这样我必须手动添加所有引用的类。

原文

I need to run shell commands (in my case ipfw) in Java with root privileges. I use ProcessBuilder to run commands with no privileges:

Process p = new ProcessBuilder("ls","/").start();

BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream()));

String s;
while((s=br.readLine()) != null) {
    System.out.println(s);
}

This code work fine but I need to run something like sudo root command. How can I do?

I need to run this program in Eclipse, Mac OS X 10.6.8

Edit: for now I use sudo java nameclass from terminal but in this way I have to manually add all the referenced classes.
