Clear text password - how to send it from java.

Question

I am trying to reset the password of a user from java.
So I have to open a socket connection to Unix box and send a packet in following format
"<adminUserid> <adminPassword> PASSWORD <target-userId> <new-passwd>\n"
So they say that user credentials are to be send in cleartext
Please tell me how i can send above string as cleartext
thanks in advance.

But this is not working for me , UNIX gurus please help
import java.net.InetAddress;
import java.net.Socket;
import java.net.UnknownHostException;
import java.io.BufferedWriter;
import java.io.OutputStreamWriter;
import java.io.IOException;
public class TestUnix {
public static void main(String args[] ) {
     try {
             InetAddress addr = InetAddress.getByName("x.x.x.x");
             int port = 6546;
          System.out.println("Address IP : "+addr);
             // This constructor will block until the connection succeeds
             Socket socket = new Socket(addr, port);
          BufferedWriter wr = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));
          String command = "<Admin><admin-pwd>PASSWORD<user><user-pwd>\n";
          System.out.println(command);
                 wr.write(command);
             wr.flush();
          socket.close();
          System.out.println("Finished executing");
         } catch (UnknownHostException e) {
