Mac firewall setting with java

I'm going to add some rules in my firewall with java, I'd like to execute this command with java:

String [] cmd = {"sudo ipfw delete 100 "};
Runtime.getRuntime().exec(cmd);

But I get this error

Cannot run program "sudo ipfw delete 100 ": error=2, No such file or directory

Any suggestion?

This is common error output for Runtime.exec on *nix platforms. Ensure that both sudo and ipfw are on your path in your runtime environment.

Alternatively you could specify the full path locations:

String [] cmd = {"/path_to_sudo/sudo", "/path_to_ipfw/ipfw", "delete", "100"};

Wrt the password for sudo, you could have the password in your command although there is a clear security risk with this(!)

One solution is to read the password from your application.

I would try the full path to ipfw /sbin/ipfw and possibly sudo as well.

One question would be how do you plan to deal with entering the password like this?
