Just off the top of my head, the following (pseudo code) is how I'd stab at it; should point in the right direction anyway. If you want a response you'll need to create the corresponding DataInputStream.

import java.net.*

//create a Socket object connected to port 514 (shell/cmd port used by rsh)

Socket mySock = new Socket("destination host",514);

//get the output stream for the socket

DataOutputStream outStream;

outStream = new DataOutputStream(mySock.getOutputStream());

//construct the command string

String rshStr = "whatever command you want to send"

//send it on its way

outStream.writeBytes(rshStr);

outStream.write(13);

outStream.write(10);

outStream.flush();

This assumes you have rsh set up on the host and you send an appropriate username with the command if required.
Hope this helps.
