thanks, but what I´m trying is :

I´ll have one computer that controls a system by serial port.
I´ll have to control the system by web.

So I´m trying to send a value by an applet to a web server, if the applet 
could open a socket, I´ll comunicate by sockets with th computer system.

It´s very simple, but I saw on sun´s java site that I just can open a 
socket comunication on the same computer where´s the applet.

The RMI´s isn´t solution to because the serial port.

If you have any sugestion, thanks.
