My stupid webmanager, write a java applet, and the applet wants to open tcp 443 port. in Linux machine, only root can use tcp 443 port. so he lets us use "sudo firefox". it's very bad idle. so I try to write a wrap, this wrapper helps user to get root permission when runs the applet. than firefox is normal user's process. wrapper is easy to write, but how can I customer java path. BTW, I want only firefox to use this wrapper.
